Frequently Asked Questions
AlgaeCal sells the world’s only calcium supplement that increases bone density.
Since 2002, AlgaeCal has the worldwide exclusive rights to Mesophyllum Superpositum, an organic South American sea algae. This sea algae is milled into an organic powder called AlgaeCal Plus – AlgaeCal’s flagship product.
AlgaeCal Plus contains plant calcium, magnesium, boron, manganese, silica, selenium, copper, nickel, strontium, phosphorus, potassium, vanadium and zinc. These naturally-occurring minerals are milled into an organic powder and combined with vitamins C, D, and K2.
AlgaeCal Plus is the only supplement shown to increase bone mineral density in human clinical trials.
In addition to AlgaeCal Plus, AlgaeCal also sells Strontium Boost, AlgaeCal, and Triple Power Omega 3 Fish Oil.
AlgaeCal Plus
What is AlgaeCal Plus?
AlgaeCal Plus is a plant-based calcium supplement made from a unique South American marine algae called Mesophyllum superpositum. These USDA-certified organic algae are sustainably hand-harvested from the ocean, gently sun-dried, and milled into a fine powder.
Unlike traditional calcium supplements, which are typically derived from rocks like limestone or marble, AlgaeCal Plus is a whole-food source of all 13 essential bone-supporting minerals: calcium, magnesium, manganese, phosphorous, nickel, silica, copper, vanadium, potassium, zinc, boron, selenium and strontium. And because it comes from a living plant, this natural mineral matrix is easier for your body to absorb and utilize.
In addition to these 13 minerals we also add full clinical doses of vitamins C, D, and K.
Clinical research published in three peer-reviewed scientific journals shows that the 16 nutrients in AlgaeCal Plus don’t just slow bone loss; they can actually help increase bone density in adults. No other calcium supplement can make this claim. Because AlgaeCal is the ONLY one that’s clinically supported to increase bone density.
How many AlgaeCal Plus capsules should I take and when should I take them?
To maximize your bone-building, take 4 capsules of AlgaeCal Plus a day. (This was the dosage that led to the most significant bone density increases in clinical trials).
We recommend splitting the daily 4 capsule dose into 2 servings of 2 capsules throughout the day. Your body can only absorb 500mg of calcium at a time, so taking more than 2 AlgaeCal capsules in one serving would lead to unabsorbed calcium.
And finally, it’s best to take your AlgaeCal Plus with food. That’s because taking calcium with food increases how well you absorb it. When you eat, your stomach produces acid that dissolves the minerals in AlgaeCal Plus so they can be properly absorbed when they reach your intestinal tract.

What ingredients are in AlgaeCal Plus?
AlgaeCal Plus contains 16 nutrients clinically supported to increase bone density.
In fact, AlgaeCal is the only calcium supplement in the world with human clinical studies showing actual increases in bone density—not just a slowdown in bone loss.
These nutrients work together to build new bone and protect the bone you already have:
Plant-Based Minerals (from the USDA-certified organic Mesophyllum superpositum.)
- Calcium – the main structural mineral that gives bones their strength and hardness.
- Magnesium – activates vitamin D and supports the formation of new bone tissue.
- Boron – enhances absorption of calcium and magnesium and helps regulate bone-protective hormones.
- Zinc – essential for collagen synthesis and bone tissue repair.
- Copper – works with zinc to create strong collagen cross-links for flexible, resilient bones.
- Manganese – aids the production of bone cartilage and connective tissue.
- Selenium – powerful antioxidant that protects bone cells from oxidative stress.
- Strontium – naturally occurring trace mineral that supports bone formation and slows bone breakdown.
- Silica (Silicon) – helps initiate bone mineralization and supports collagen production.
- Vanadium – assists enzymes involved in bone growth and mineral metabolism.
- Nickel – required in tiny amounts for enzymes that support bone and cartilage formation.
- Phosphorus – partners with calcium to form the mineral crystals that harden bone.
- Potassium – helps neutralize excess acids in the body that can draw minerals out of bones.
Added Bone-Building Co-Factors
- Vitamin D3 – enhances calcium and magnesium absorption so minerals reach your bones.
- Vitamin K2 (MK-7) – directs calcium into bone and keeps it out of arteries.
- Vitamin C – stimulates collagen production, creating the flexible framework where minerals attach.
AlgaeCal Plus is dairy-free, soy-free, gluten-free, non-GMO, and contains only naturally occurring trace minerals—no synthetic fillers or artificial additives. While we don’t third-party test for these allergens, none are added during manufacturing.
Do I have to take both AlgaeCal and Strontium Boost?
You don’t have to, but if you’re dealing with bone loss, taking AlgaeCal Plus together with Strontium Boost delivers the fastest results.
Clinical studies show:
- AlgaeCal Plus alone can increase bone density by an average of 1.3% per year.
- AlgaeCal Plus + Strontium Boost together produce an average 3% increase in just one year. And most people see results within the first 6 months.
So when you add Strontium Boost to your AlgaeCal Plus you’re going to build bone faster. That’s right. You’ll build more bone in less time.
And when you take both products together, you’re also covered by our Stronger Bones For Life Guarantee. So when you take AlgaeCal Plus and Strontium Boost, as directed, you’re guaranteed to see measurable bone density increases within six months – or your money back!

How much elemental calcium is in AlgaeCal Plus?
Each serving of AlgaeCal Plus provides 360 mg of elemental calcium in two capsules. That’s 720 mg per day when you take the full four-capsule daily dose.
This is the exact amount used in clinical studies that showed measurable increases in bone mineral density.
You don’t need more calcium, you need the right kind of calcium. Unlike ordinary rock-based calcium (from limestone or marble), AlgaeCal Plus delivers plant-based, whole-food calcium with 12 essential bone-building minerals + vitamins C,D,& K. These 16 nutrients are easy for your body to absorb and—most importantly—are clinically supported to increase bone density, something other calcium supplements simply can’t do.
What if I have trouble swallowing the capsules?
AlgaeCal Plus comes in size zero soft vegetarian capsules which are easy to swallow.
However, if swallowing capsules is difficult, you can gently pull them apart and sprinkle the tasteless powder into food or drinks. Semi-solid foods such as smoothies, applesauce, or yogurt work best.
Avoid mixing the powder into hot liquids above 120°F (49°C), as high temperatures can reduce the potency of vitamins C, D, and K2.
Because the powder contains a wide range of natural minerals, it is only partially water-soluble, so it won’t completely dissolve in liquid.
Does AlgaeCal Plus cause side effects like kidney stones or calcium deposits in the arteries?
No. AlgaeCal Plus is safe and without adverse side effects. Here’s why:
- Plant-based, not rock-based: Unlike traditional calcium supplements made from limestone or marble, AlgaeCal Plus is a food-source calcium similar to the calcium found in vegetables like broccoli and kale. So your body recognizes it as food and absorbs it accordingly.
- Balanced with co-factors: Each serving provides additional magnesium, boron, vitamin K2, and vitamin D3. These nutrients work together to move calcium into your bones where it belongs, and away from soft tissues like arteries, kidneys, or eyes.
- Clinically effective at a lower dose: AlgaeCal Plus increases bone density with only 720 mg of calcium per day, the exact amount used in human clinical studies. Traditional calcium supplements often recommend 1,200 mg or more—and still only slow bone loss.
Because AlgaeCal Plus delivers the right kind of calcium, in the right balance, it strengthens bones without the risks of kidney stones or arterial calcification.
Does AlgaeCal Plus cause constipation, gas or bloating?
No. AlgaeCal Plus is gentle on the stomach. The digestive discomfort many people experience with regular calcium supplements comes from their rock-based source (limestone or marble), which the human body struggles to break down.
AlgaeCal Plus is different. It provides plant-based calcium naturally balanced with magnesium and other supportive minerals, making it easy to digest and absorb, without the constipation, gas, or bloating common to traditional calcium.
For best results, split your daily dose: take two capsules with breakfast and two with dinner. Taking AlgaeCal Plus with food further improves absorption and helps keep your digestive system comfortable.
I’m petite. Do I still need the full dose?
Yes. Even if you’re small-framed, your bones require the same essential nutrients to stay strong.
In fact, being petite can actually increase your risk of bone loss because you start with less skeletal mass. So giving your body the full daily dose of AlgaeCal Plus is especially important to help protect and rebuild your bones.
Is AlgaeCal Plus tested for contaminants? Does it contain lead or other heavy metals?
Don’t worry. Every batch of AlgaeCal Plus is thoroughly tested for purity and safety.
Like all plants that grow in soil or water, the marine algae from which AlgaeCal Plus is sourced naturally contains dozens upon dozens of trace minerals, including tiny amounts of lead. But this isn’t unique. Carrots from your garden, broccoli from your local store, and the kale in your salad all contain these same trace amounts. That’s because lead is a naturally occurring element found in soil, water, and air. Plants absorb tiny amounts of it as they draw in minerals to grow. The key point is the amount: these trace levels are extremely small, far below regulatory safety limits, and your body is well equipped to clear them daily through normal processes like urine, stool, and sweat.
To ensure exceptional safety and quality:
- Every lot of AlgaeCal is third-party tested for heavy metals, mineral content, and microbial activity.
- The finished product is manufactured in an FDA-registered, GMP-certified facility that follows the highest quality standards.
- AlgaeCal Plus has 20 years of market use, three human clinical studies, and a full toxicology study demonstrating extraordinary safety.
In fact, a 7-year clinical trial found no-adverse side effects among any of the 172 study participants.
So you can feel confident knowing that AlgaeCal Plus delivers pure, plant-based nutrients, clinically supported to increase bone density and rigorously tested to meet or exceed all safety guidelines.
Can I take AlgaeCal Plus if I’m on bone medications?
Yes. All prescription bone medications require adequate calcium to give your body the raw materials it needs to build new bone. And AlgaeCal Plus provides a clinically supported, plant-based calcium that works beautifully alongside these treatments.
That said, it’s always important to check with your healthcare provider before making any changes to your supplement routine or medical care, especially if you’re currently taking prescription medications.
Can I take AlgaeCal Plus with my prescription medication?
Yes. But timing matters. To avoid any potential interactions and to ensure the best absorption of both your supplements and medications, it’s best to take AlgaeCal Plus at least 2–3 hours apart from prescription drugs. Some medications may require a 3–4 hour separation, so always check with your doctor or pharmacist for your specific situation.
Special note for blood thinners:
If you are taking an older anticoagulant (such as warfarin or Coumadin), vitamin K2 is not recommended because these drugs use the same absorption pathway and can block each other. Newer anticoagulants—called Factor Xa inhibitors (e.g., apixaban, rivaroxaban) and Direct Thrombin inhibitors (e.g., dabigatran)—do not interfere with vitamin K2 and may be safer for your bones. Ask your doctor if one of these newer options is appropriate for you.
As always, consult your healthcare provider before adding any supplement or making changes to your medication routine.
Does my doctor know about AlgaeCal?
Many doctors, especially those open to natural treatments, are already familiar with AlgaeCal. But every healthcare provider is different, and it’s always best to give them the full details yourself.
To make it easy, we’ve created a “Take It to Your Doctor” information sheet that outlines the clinical research, ingredients, and dosing. Print it out or share it at your next appointment so your doctor can give you the best, personalized guidance for your bone health.
Should I be concerned about iodine if I have a thyroid condition?
AlgaeCal Plus contains only a tiny amount of naturally occurring iodine. This is well within the normal range found in many everyday foods. For example three medium-sized potatoes will contain roughly 180 mcg.
However, if you have a thyroid condition, it’s always wise to check with your doctor to confirm that this amount is appropriate for your individual needs.
For best absorption and to avoid any interaction with thyroid medications, take AlgaeCal Plus at least 4 hours apart from your thyroid prescription.
Can I take AlgaeCal Plus if I have a shellfish allergy?
Yes. AlgaeCal Plus contains absolutely no shellfish or shellfish-derived ingredients.
And many customers with shellfish allergies take AlgaeCal Plus safely with no adverse reactions. That said, if you have a severe allergy, it’s always best to consult your doctor or allergist before starting any new supplement.
Is AlgaeCal FDA approved?
The U.S. Food and Drug Administration (FDA) does not “approve” dietary supplements. It only approves prescription medications. Because AlgaeCal Plus is a natural supplement, it isn’t eligible for FDA approval.
However, AlgaeCal is registered with the FDA and holds GRAS status (Generally Recognized as Safe). GRAS means a qualified panel of independent experts has reviewed the science and determined the ingredient is safe for its intended use.
Is AlgaeCal Plus vegan?
No. AlgaeCal Plus is vegetarian. But not vegan. The calcium and other minerals come from plant-based marine algae, but the vitamin D3 is derived from lanolin (the natural wax found in sheep’s wool) which is an animal by-product.
Lanolin is sustainably harvested and does not harm the animals, but because it originates from an animal source, AlgaeCal Plus is classified as vegetarian, not vegan.
Is AlgaeCal Plus gluten-free and soy-free?
Yes. AlgaeCal Plus is completely free of gluten, soy, and dairy—and it’s non-GMO.
Why does AlgaeCal Plus use magnesium oxide?
AlgaeCal Plus provides magnesium from two sources:
- Naturally occurring magnesium from the organic marine algae Mesophyllum superpositum.
- A small amount of added magnesium oxide to achieve an optimal 2:1 calcium-to-magnesium ratio. This is the same balance found in healthy human bone and the exact ratio used in the clinical studies on AlgaeCal.
Research shows that this precise magnesium ratio, when taken within the AlgaeCal Plus protocol, is clinically supported to increase bone density.
Strontium Boost
I’ve heard that strontium isn’t safe. Is that true?
Some people have read scary headlines about strontium and worry it could cause heart problems or blood clots. But here’s the truth: those warnings come from a drug called strontium ranelate. Not the natural mineral we use.
The Source of the Confusion
- Strontium ranelate was a synthetic prescription drug used in Europe for osteoporosis.
- Early studies showed impressive bone density gains, but later trials revealed a small increase in heart attacks, strokes, and blood clots.
- Regulators restricted its use in 2014, and it was eventually pulled from the market in 2017.
- These events, and the media coverage around them, created the myth that all strontium is unsafe.
The Form We Use: Strontium Citrate
- Strontium citrate is completely different.
- It’s a natural mineral salt—strontium is already found in small amounts in vegetables like broccoli, carrots, and potatoes, and “citrate” is a natural agricultural product.
- This is the form used in Strontium Boost, and it has been studied for years with no cardiovascular risks.
- In one 7-year study published in The Journal of the American College of Nutrition, people taking strontium citrate with a plant-based calcium supplement gained bone density every year with no safety concerns on blood tests.
Bottom Line
Strontium ranelate (the drug) and strontium citrate (the mineral) may sound alike, but they couldn’t be more different.
- Strontium ranelate = synthetic drug, linked to heart risks, no longer on the market.
- Strontium citrate = natural mineral, clinically supported to safely support bone density.
When you see the name Strontium Boost, you can be confident it contains strontium citrate only—no drug ingredients and no ranelate.
Does Strontium Boost artificially inflate DEXA results?
Yes and no. Strontium acts a lot like calcium. So your body will naturally use some of it when building new bone. Over time, about 1 in every 10 calcium ions in your bones can be filled by strontium instead.
Here’s why that matters: strontium is heavier than calcium. A DEXA scan measures mineral weight to estimate bone density, so the extra weight of strontium can make the scan look about 8–11% higher than the true calcium content.
But that doesn’t mean the gains are fake. So if your scan shows a 10% increase, the “strontium effect” might account for a few percent of that overall increase. But that doesn’t change the fact that you’re still increasing bone density. Think of it this way: if your DEXA scan shows a 10% increase, and you adjust for the 8–11% overstatement caused by strontium’s weight, you’re still left with a real improvement of roughly 9%.
So yes, the numbers may be slightly inflated. But your bones are still getting stronger. And that’s exactly what you want.
Does Strontium increase bone density?
Yes. Strontium actively builds stronger bones and clinical studies support it.
When you take Strontium Boost, it supports bone in two key ways:
1. Stimulates bone-building cells (osteoblasts)
2. Slows bone-breaking cells (osteoclasts)
This double action—more building, less breakdown—means you build more bone in less time.
In human clinical studies, participants taking AlgaeCal Plus alone increased bone density by an average of 1.3% per year. However, when AlgaeCal Plus was combined with Strontium Boost, bone density increased by an average of 3% per year.
And the best part? Many study participants saw these increases in as little as six months.
AlgaeCal
Is AlgaeCal right for me?
AlgaeCal (as opposed to AlgaeCal Plus) is recommended for anyone who cannot take AlgaeCal Plus because of vitamin K2. If you’re using an older anticoagulant (blood thinner), such as warfarin or Coumadin, vitamin K2 can interfere with the medication, so AlgaeCal Plus isn’t suitable. In that case, regular AlgaeCal (without vitamin K2) is the safer choice.
However, many people today are prescribed newer anticoagulants, called Factor Xa inhibitors (e.g., apixaban, rivaroxaban) or Direct Thrombin inhibitors (e.g., dabigatran).
These medications do not interact with vitamin K2, which means AlgaeCal Plus can often be taken safely alongside them.
If you’re on a blood thinner, talk to your doctor about which type you’re using and whether a newer medication might allow you to benefit from AlgaeCal Plus. If switching isn’t an option, AlgaeCal is your best alternative for plant-based calcium and minerals.
AlgaeCal is the ONLY calcium supplement clinically supported to STOP bone loss.
What’s the difference between rock-based calcium and plant-based calcium?
It all comes down to source and absorption.
Rock-based calcium
Most conventional calcium supplements are made by grinding up rocks such as limestone or marble. Chemically, this produces calcium carbonate or calcium citrate—forms that are essentially purified stone. And because humans are not designed to digest rock, these supplements:
- Absorb poorly in the digestive tract, especially if stomach acid is low (which becomes more common with age).
- Provide only calcium and little else, leaving out the dozens of trace minerals your bones need to increase bone density
- Often require high daily doses (1,000–1,200 mg) to have even a modest effect—and even then, clinical studies show they merely slow bone loss rather than increase bone density.
Plant-based calcium
Plant calcium comes from living organisms—for example, the marine algae used in AlgaeCal (Mesophyllum superpositum). This algae absorbs a wide spectrum of ocean minerals as it grows, creating a natural mineral matrix similar to human bone.
Key advantages include:
- Better absorption: Your body recognizes plant minerals as food, allowing more efficient uptake even at lower doses (the 720 mg in AlgaeCal was the exact amount used in clinical trials that stopped bone loss).
- Complete mineral profile: Along with calcium, the algae naturally provides magnesium, boron, silica, zinc, and other trace minerals proven to support new bone formation.
- Clinical evidence: Human studies show plant-based AlgaeCal not only slows bone loss, but can stop bone loss—something no other calcium has ever demonstrated.
Bottom line
Rock-based calcium is literally ground stone. Hard to absorb and incomplete. Plant-based calcium is food for your bones: easier to digest, naturally balanced with essential co-factors, and clinically shown to help your bones grow stronger
What is the difference between AlgaeCal and other algae-based calciums?
AlgaeCal isn’t just another algae calcium. It’s the only one of its kind.
- Exclusive Source:
AlgaeCal has the worldwide exclusive rights to a rare red marine algae called Mesophyllum superpositum. No other supplement company can use this species. This unique algae naturally absorbs a complete spectrum of 13 bone-supporting minerals in ratios that closely match human bone.
- Clinically Supported:
AlgaeCal is the only calcium supplement—of any kind—that is supported by published human clinical studies showing actual increases in bone density.
Other algae-based calciums may provide plant calcium, but none have peer-reviewed research demonstrating measurable bone gains.
Because of this exclusive species and unmatched clinical evidence, AlgaeCal stands alone as the only algae-based calcium that is both unique in source and supported to strengthen bones.
What is in AlgaeCal?
Every serving of AlgaeCal delivers a whole-food mineral complex harvested from the exclusive marine algae Mesophyllum superpositum—plus added vitamin D3 to help your body absorb it. Together, these nutrients create the complete mineral matrix clinically supported to stop bone loss:
Naturally Occurring Minerals (from the algae)
- Calcium – the primary structural mineral of bone
- Magnesium – helps activate vitamin D and supports new bone formation
- Boron – aids calcium and magnesium absorption and supports bone-protective hormones
- Zinc – essential for collagen production and bone tissue repair
- Copper – strengthens collagen cross-links for resilient bones
- Manganese – assists in cartilage and connective tissue formation
- Selenium – antioxidant that protects bone cells from oxidative stress
- Strontium – supports bone formation and reduces bone breakdown
- Silica (Silicon) – promotes collagen production and mineralization
- Vanadium – helps regulate enzymes involved in bone growth
- Nickel – trace mineral involved in bone and cartilage enzyme function
- Phosphorus – partners with calcium to form the mineral crystals that harden bone
- Potassium – helps maintain a pH balance that prevents mineral loss from bone
Added Nutrient
- Vitamin D3 – enhances calcium absorption so minerals reach your bones
How many AlgaeCal capsules should I take, and when?
For the best bone-health results, take 3 AlgaeCal capsules per day. This is the same daily amount used in the clinical studies where participants saw measurable improvements in bone density after one year.
How to take it
- Split the dose: Take one capsule three times a day (for example, with breakfast, lunch, and dinner).
- Always take with food: Calcium absorbs best when your stomach produces acid during a meal. Stomach acid helps dissolve the minerals in AlgaeCal so they can be fully absorbed in the intestines.
If you take prescription medications or other supplements, leave a 2–3 hour gap between AlgaeCal and your medication unless your healthcare provider advises otherwise.
What’s the difference between AlgaeCal and AlgaeCal Plus?
Take AlgaeCal to STOP bone loss. Take AlgaeCal Plus to INCREASE bone density. Both products begin with the same foundation: plant-based calcium from our exclusive red marine algae (Mesophyllum superpositum), which naturally provides all 13 essential bone-supporting minerals.
AlgaeCal is ideal for people who cannot take vitamin K2, such as those using older anticoagulant (blood-thinning) medications like warfarin or Coumadin, because it delivers the complete mineral matrix with vitamin D3 and without vitamin K2.
AlgaeCal Plus contains everything in AlgaeCal but goes a step further by adding vitamin C for collagen formation and vitamin K2-7 (MK-7) to guide calcium safely into bones and away from soft tissues, while also providing slightly more vitamin D3, magnesium, and boron for even stronger bone support.
Clinical studies show that AlgaeCal Plus produces the greatest improvements in bone density, so if you’re not on an older blood thinner—or if you’ve switched to a newer anticoagulant that doesn’t interact with K2—AlgaeCal Plus is the best choice for maximum bone-building benefits.
AlgaeCal Collagen
What type of collagen is AlgaeCal Collagen?
AlgaeCal Collagen delivers a unique blend of four clinically supported collagen peptides:
VERISOL®: Type I & III collagen shown to reduce wrinkles and improve skin elasticity.
FORTIGEL®: Type II collagen that supports joint cartilage and mobility.
UC-II®: Undenatured Type II collagen that helps maintain healthy joint function and comfort.
FORTIBONE®: Type I collagen clinically supported to stimulate bone-building cells and improve bone health.
Together, these collagens work from the inside out to support bones, joints, skin, hair, and nails, giving your body the same structural proteins it naturally relies on for strength, structure and flexibility.
How do I use this product?
Simply mix one scoop of AlgaeCal Collagen into your favorite hot beverage for a full clinical dose of the four collagens. The powder is completely flavorless and odorless, so it won’t change the taste of your drink, and it dissolves easily with no clumping. For best blending, add the powder to your cup before pouring in the liquid. You can also stir a scoop into a smoothie or sprinkle it over meals for the same bone, joint, and skin benefits.
Are there any allergens in this product?
AlgaeCal Collagen itself contains no known allergens. It’s completely free of dairy, gluten, soy, and shellfish. However, it is produced in a facility that also handles products containing common allergens. The facility follows strict Good Manufacturing Practices (GMP) to prevent cross-contamination, but the finished product is not specifically tested for every potential allergen. If you have a severe allergy, we recommend reviewing the ingredient list and consulting your healthcare provider before use.
How long does it take to see results from this product?
In clinical studies participants saw visible benefits from VERISOL® in as little as 28 days, with participants noticing improved skin elasticity and smoothness within the first month. Continued use delivers deeper changes—such as stronger hair and nails, reduced appearance of cellulite, and improved joint comfort and mobility—typically within 2 to 6 months. Individual results will vary, but consistent daily use is key to achieving the full spectrum of clinically supported benefits.
Can I mix this collagen supplement with hot beverages?
Yes! AlgaeCal Collagen is heat-stable, flavorless, and odorless, so you can safely mix it into hot drinks like coffee, tea, or hot chocolate without affecting taste or potency. It dissolves smoothly with no clumping, especially if you add the powder to your cup before pouring in the liquid. Whether it’s part of your morning coffee or an evening herbal tea, you’ll get the full clinical dose of all four collagens in every scoop.
Is this product suitable for children?
Collagen production naturally begins to decline around age 30, but research shows benefits for younger people as well. In fact, a clinical study of 147 young athletes (average age 20) found that FORTIGEL® collagen helped reduce activity-related joint pain. That said, for children or teenagers, it’s always best to consult a pediatrician or healthcare provider before starting any supplement to ensure it’s appropriate for their age and individual health needs.
Can AlgaeCal Collagen help with joint pain?
Yes. Clinical studies on two of the key collagens in AlgaeCal Collagen show meaningful support for joint comfort.
- In the FORTIGEL® clinical studies, participants experienced less activity-related joint pain than those taking a placebo, which reduced their reliance on over-the-counter pain relievers, ice packs, and physiotherapy.
- UC-II® clinical studies found significant improvements in joint flexibility and comfort during everyday movements such as climbing stairs, bending, and squatting.
Together, these results show that the patented collagens in AlgaeCal Collagen can help reduce joint discomfort and improve mobility when used consistently.
What are the benefits of AlgaeCal Collagen?
AlgaeCal Collagen combines four patented, clinically supported collagens VERISOL®, FORTIGEL®, UC-II®, and FORTIBONE®. Together these are backed by 25 human clinical trials (18 double-blind, placebo-controlled) to help reduce wrinkles, improve skin elasticity, smooth the appearance of cellulite, and increase hair thickness and shine. It also supports stronger, faster-growing nails, promotes knee cartilage health, enhances joint flexibility and comfort, reduces activity-related knee pain, and even helps improve bone health.
All that from just one scoop in your morning coffee!
Is this collagen product suitable for vegetarians or vegans?
No. AlgaeCal Collagen is neither vegetarian nor vegan. There is no such thing as vegan collagen. Our formula is made with collagen peptides sourced from pasture-raised bovine (beef) and cage-free chicken. If you follow a vegetarian or vegan diet, you may want to focus on nutrients that help your body produce its own collagen, such as vitamin C, zinc, and amino acids from plant proteins.
Can I take this product if I have a medical condition, am pregnant or nursing, or take prescription medication?
AlgaeCal Collagen is made from natural, food-based ingredients, but it’s always best to check with your healthcare provider before starting any new supplement—especially if you have a medical condition, take prescription medications, or are pregnant or nursing. Your doctor can review the ingredients and ensure it’s appropriate for your individual health needs.
How long can I take collagen?
Collagen is a naturally occurring protein in the body, and supplementing with it is considered safe for long-term, daily use. In fact, clinical studies on the key collagens in AlgaeCal Collagen have followed participants for up to four years with no safety concerns. As with any supplement, if you have a medical condition or take prescription medications, it’s always a good idea to check with your healthcare provider to make sure long-term use is appropriate for you.
Triple Power Omega 3 Fish Oil
Does Triple Power come in a capsule?
No. Triple Power is in a liquid emulsion, so it is taken by tablespoon. Emulsions have been shown to be 300% better absorbed than standard fish oil capsules. This form is also less prone to oxidation and is digested and metabolized more quickly and completely than standard fish oil capsules.
How many tablespoons of Triple Power should I take, and when?
For adults with healthy omega-3 levels, the recommended dose is 1 tablespoon daily with food to maintain optimal levels.
If your omega-3 levels are below the healthy range, we recommend a double dose—2 tablespoons daily with food—for 90 days. This “loading phase” helps quickly restore omega-3 levels and is a key part of our Triple Guarantee and 90-Day Oil Change Challenge.
After 90 days, you can return to the standard 1 tablespoon daily for ongoing support.
To confirm your omega-3 status, we recommend testing your blood levels. For more information on our guarantee and how to get tested, click here.
For children, please consult your pediatrician for appropriate dosing.
Does it taste fishy?
Not at all! Triple Power is guaranteed to be fresh, burp-free, and completely free of any fishy taste or smell. It’s naturally flavored with refreshing mango and lightly sweetened with xylitol, a plant-based sweetener found in fruits. The result is a smooth, pleasant flavor you’ll actually look forward to. No fishy aftertaste, and no “fish burps.”
Is one bottle of Triple Power a one-month supply?
Yes. One bottle provides a 29-day supply when taking the standard dose of 1 tablespoon per day. If you're following a double-dose protocol to raise your omega-3 levels (2 tablespoons per day), the bottle will last approximately 14 days. After the 90-day loading phase, you can return to the standard dose, and each bottle will once again last nearly a full month.
What types of fish are used in Triple Power? And what about heavy metals and contaminants?
Triple Power is made from fresh, wild-caught anchovies, sardines, and mackerel. These small, oily fish are sustainably sourced from cold Pacific waters near Peru. These fish are naturally rich in omega-3s and, because they’re lower on the food chain, they carry far fewer heavy metals and toxins than larger species like tuna or swordfish.
To ensure absolute purity, we go a step further by using molecular distillation, a process that gently removes any remaining contaminants. The result is an ultra-pure, refined fish oil with virtually no detectable heavy metals, PCBs, or toxins—making it one of the cleanest sources of EPA and DHA available.
This level of purity is especially important for women concerned about mercury exposure—particularly during pregnancy. That’s why molecularly distilled fish oil like Triple Power is considered one of the safest and most beneficial ways to support both maternal and fetal health.
What are the side effects of Triple Power?
Triple Power is well-tolerated and has not been shown to cause any adverse side effects or reactions. Unlike standard fish oils that often cause burping, bad breath, or a fishy aftertaste, Triple Power is formulated as a fresh, emulsified liquid that’s easy to digest and backed by our Triple Guarantee—which includes a burp-free promise.
If you have a medical condition, are taking medication, or are pregnant or nursing, we always recommend speaking with your healthcare provider before starting any new supplement.
Is Triple Power gluten-free and soy-free?
Triple Power is gluten-free, dairy-free, and non-GMO. However, it does contain a very small amount of mixed tocopherols (vitamin E compounds) derived from soy. These are added as natural antioxidants to protect the delicate fish oil from oxidation and preserve its freshness.
Importantly, the tocopherols go through a highly refined process that removes all soy protein, which is the component responsible for allergic reactions. This level of purification is standard in many high-quality fish oils.
If you have a severe soy allergy, we recommend consulting your doctor or allergist before use, just to be safe.
What is the “Triple Guarantee”?

Why is Triple Power sweetened?
To make it enjoyable, Triple Power is naturally sweetened with xylitol, a plant-based sweetener found in fruits and vegetables. Xylitol not only improves taste, but it also has oral health benefits and is gentle on blood sugar levels.
If you find Triple Power a little too sweet for your preference, you can easily mix it into foods like plain Greek yogurt or smoothies. Just avoid hot liquids, as heat may alter the delicate structure of the fish oil and reduce its effectiveness.
For more information on our sweetener of choice, check out our article on the benefits of xylitol.
Do I need fish oil?
Fish oil has been one of the most well-researched supplements over the past several decades, with studies consistently showing benefits for heart health, brain function, joint comfort, and inflammation management. It’s particularly valued for its content of omega-3 fatty acids (EPA and DHA)—nutrients that many people don’t get enough of through diet alone.
Triple Power delivers a full dose of these essential omega-3s, and goes further by including two highly studied antioxidants: curcumin (from turmeric) and astaxanthin. This combination supports a healthy inflammatory response, making it a smart choice for long-term health and everyday comfort.
Can I take Triple Power if I’m pregnant or breastfeeding?
Yes, absolutely! Omega-3 fatty acids are especially important during pregnancy and breastfeeding. They play a key role in supporting fetal brain and eye development, as well as the overall health of both mother and baby.
Because the body can’t produce omega-3s on its own, they must come from your diet. Typically through fatty fish or fish oil. However, health authorities recommend that pregnant women limit fish intake to no more than two 6-ounce servings per week due to potential exposure to mercury and other environmental toxins.
Triple Power is a safer alternative. It uses molecular distillation, a purification process that removes virtually all contaminants, including mercury, PCBs, and heavy metals—resulting in an ultra-pure, refined fish oil.
As always, we recommend checking with your healthcare provider before starting any supplement during pregnancy or breastfeeding.
What is the OmegaQuant Omega-3 Blood Test Kit?
OmegaQuant is a simple, at-home blood test kit that allows you to test your blood omega 3 levels in seconds! Red blood cell levels of omega 3s are representative of the levels found in your brain and heart, and low levels are linked to disease and early death. By testing your levels you will be able to supplement accordingly with the amount of omega 3 fatty acids optimal for YOU. Go here for more on the leader in omega 3 testing.
Magnesium Relax
How long does it take to feel a difference?
Clinical studies on key ingredients like Sensoril® Ashwagandha and magnesium show significant results in as little as 60 days‡*.
Will it make me feel groggy or drowsy the next day?
No. Magnesium Relax is non-sedating. It supports your body’s natural ability to power down at night — without knocking you out or leaving you foggy the next morning‡*.
What makes AlgaeCal Magnesium Relax™ different from other magnesium supplements?
It’s not just magnesium. Magnesium Relax includes the active form of vitamin B6 (P5P), zinc, and Sensoril® Ashwagandha — clinically shown to reduce stress by up to 62%. Plus, the AlgaeCal Absorb™ blend helps your body actually absorb and use these nutrients.*
Is this safe to take daily?
Yes. The ingredients in Magnesium Relax play a crucial role in over 300 biochemical processes in the human body. Worryingly, almost 50% of adults are deficient in these essential nutrients. Replacing these nutrients helps to support your nervous system and helps your body––and brain––to relax.
Do I need AlgaeCal Magnesium Relax™ if I’m already taking AlgaeCal Plus?
Yes. While AlgaeCal Plus contains 350 mg of magnesium (as magnesium oxide) to support bone density, Magnesium Relax uses a different blend: Magnesium Bisglycinate (chelated), Magnesium Citrate, and Magnesium Malate. These forms are highly absorbable and specifically chosen to support relaxation, sleep, and stress relief — not just bones.
In short: AlgaeCal Plus primarily supports your bones. Magnesium Relax soothes your nervous system.
D3 Complete
I already take a multivitamin with vitamins A, E, and K. Will I be getting too much if I also take D3 Complete?
No. D3 Complete is carefully formulated to provide safe, effective levels of vitamins D, A, E, and K, even if you're already taking a standard multivitamin.
Most multivitamins contain relatively small amounts of these fat-soluble vitamins, while D3 Complete offers clinically relevant doses in a balanced ratio that supports optimal absorption and function. The nutrients in D3 Complete are designed to work together, helping your body use them more effectively and safely.
That said, if you have any medical conditions or are taking high-dose supplements separately, it’s always a good idea to check with your healthcare provider to ensure your total intake is appropriate for your individual needs.
How much Vitamin D should I take daily?
It depends. A variety of factors such as age, weight, skin color, and even geographical location affect the amount of Vitamin D a person needs. At the lower level, recommendations from The National Institutes Of Health and the Endocrine Society range from 400-2000 IU. Whereas a recent large-scale study from Germany recommends a much higher range. That’s why it’s best to discuss your Vitamin D needs with your healthcare provider, who has the full overview of your personal needs.
What are the symptoms of Vitamin D deficiency?
Most people with Vitamin D deficiency don’t notice any symptoms. That’s why it’s important to get tested. However potential signs of Vitamin D3 deficiency include muscle and bone pain, heightened sensitivity to pain, a tingling sensation in the hands or feet (often described as "pins-and-needles"), muscle weakness in areas close to the body's core such as the upper arms or thighs, a waddling gait caused by muscle weakness in the hips or legs, a history of previous bone fractures, muscle twitches or tremors, and muscle spasms.
There’s already vitamin D3 in AlgaeCal Plus. Do I need more to increase my bone density?
No. The nutrients in AlgaeCal Plus have everything you need to increase your bone density. This has been demonstrated in multiple clinical studies and thousands of DEXA bone scans.
That said, some customers choose to take extra vitamin D3 for reasons beyond bone health.
That’s because vitamin D3 also plays a role in supporting:
- Immune function
- Heart and cardiovascular health
- Cognitive performance
- Muscle strength and coordination
If you’re considering adding more D3 to your routine, it’s always best to check your vitamin D levels through a blood test and consult with your healthcare provider to determine the right dose for your individual needs.
What are the main benefits of Vitamin A?
Vitamin A is essential for several key areas of health:
- Vision: It’s critical for night vision and overall eye health. Vitamin A supports the production of rhodopsin—a pigment in the retina that helps you see in low light. Adequate levels help prevent night blindness and may reduce the risk of age-related macular degeneration.
- Immune Support: Vitamin A plays a central role in the development and function of immune cells. It helps your body defend against illness and infection.
- Skin Health: It promotes healthy skin by supporting cell turnover and collagen production. As an antioxidant, it also protects skin cells from free radical damage—helping to maintain a youthful, radiant appearance.
In short, Vitamin A supports your eyes, immune system, and skin—making it a vital nutrient for both daily function and long-term health.
I heard vitamin A is bad for you. Is that true?
Only if you get too much of it. Like many nutrients, vitamin A is essential in the right amount, but excessive doses can be harmful. Research shows that very high intakes may lead to symptoms like headaches, dizziness, nausea, and blurred vision.
But here’s the good news: The upper safe limit for vitamin A in adults is 3,000 mcg RAE per day. D3 Complete contains just 550 mcg RAE per softgel—well within safe limits, even if you're getting additional small amounts from food or a multivitamin.
So when taken as directed, D3 Complete gives you the benefits of vitamin A without the risk of overdoing it.
Where is D3 Complete made?
D3 Complete is proudly made in the USA, in a facility that meets the highest quality and safety standards. It’s produced in an NSF-certified, cGMP-compliant facility, which means every batch is manufactured according to the strictest guidelines for purity, potency, and consistency.
Why is D3 Complete a deep brown color?
The rich brown hue is completely natural. It comes primarily from the Vitamin E, which is sourced from the seeds of the Annatto plant. This is a natural botanical known for its deep, vibrant color. No artificial dyes or colors are added.
Why is this product not available in Canada?
Even though there is no Tolerable Upper Intake Level for Vitamin K due to its strong safety profile and wide range of benefits, Health Canada places limitations on the amount of Vitamin K included in health supplements. This is outside of our control. D3 Complete can be purchased in the US and internationally only.
What is a healthy range for Vitamin D?
There is some debate about the optimal level of Vitamin D in the blood. For example, a study from the Boston University School of Medicine found a range of 40-60 ng/ml was needed to achieve the full range of health benefits conferred by Vitamin D. And another study from the University of California, found that a slightly higher range of 60-80 ng/ml was associated with even greater benefits. But ultimately, your optimal levels will depend on your current health status and health goals.
What are the main benefits of Vitamin D?
Vitamin D plays a critical role in several key areas of health:
- Bone Health: Vitamin D helps your body absorb calcium — a mineral essential for building and maintaining strong bones. Without enough vitamin D, calcium can’t do its job, increasing your risk of bone loss and fractures over time.
- Immune Function: Vitamin D supports a balanced immune response. It helps activate immune cells that detect and destroy harmful pathogens, while also keeping inflammation in check. This is why low vitamin D levels have been linked to increased susceptibility to illness.
- Muscle Function: Adequate vitamin D supports proper muscle contraction and strength. Research shows that it may reduce the risk of falls and support mobility, especially in older adults.
- Mood and Mental Health: Vitamin D receptors are found throughout the brain. Some studies suggest that low levels of vitamin D may be associated with mood disorders such as seasonal affective disorder (SAD) and depression.
In short, vitamin D is essential for more than just bone health. It supports your whole-body health every single day.
What are the main benefits of Vitamin K?
Vitamin K2 plays a critical role in maintaining optimal bone health by supporting bone metabolism and mineralization. It activates osteocalcin, a protein responsible for binding calcium to the bone matrix, which enhances bone strength and reduces the risk of fractures, osteoporosis, and age-related bone loss. Additionally, Vitamin K2 helps regulate calcium distribution throughout the body, preventing calcium from accumulating in arteries and soft tissues. Directing calcium towards the bones and teeth instead, it supports cardiovascular health, reducing the risk of arterial calcification and cardiovascular disease. Furthermore, Vitamin K2 promotes dental health by facilitating proper mineralization of teeth and preventing tooth decay. It also shows potential benefits for cognitive function, as studies suggest it may protect against cognitive decline. Lastly, Vitamin K2 possesses antioxidant properties that help combat free radicals. By modulating oxidative stress, Vitamin K2 contributes to overall health and well-being. Whereas Vitamin K1, or phylloquinone, plays a vital role in blood clotting, bone health, cardiovascular health, and acts as an antioxidant.
I take anticoagulant medication. Can I take this?
If you're taking an older blood-thinning medication (like warfarin or similar anticoagulants), it's important to be cautious with supplements that contain vitamin K or high doses of vitamin E (over 180 mg/day), as these can interfere with how your medication works.
D3 Complete contains balanced amounts of vitamins A, D3, E, and K2 — specifically designed to support bone and overall health. However, because vitamin K2 can impact blood clotting, you should consult your doctor or pharmacist before using D3 Complete to ensure it's appropriate for your individual needs and medication regimen.
Your healthcare provider can help determine what’s safe based on your dosage, bloodwork, and current treatment plan.
What are the main benefits of Vitamin E?
Vitamin E offers a range of important health benefits. Primarily known for its potent antioxidant properties, it helps protect against cellular damage caused by free radicals. When it comes to the skin, Vitamin E plays a vital role by moisturizing and nourishing the skin, aiding in wound healing, and combating the signs of aging. Moreover, Vitamin E supports a healthy immune system by enhancing the function of immune cells and bolstering our defenses against infections and illnesses. In terms of heart health, Vitamin E's ability to prevent the oxidation of LDL cholesterol (commonly referred to as "bad" cholesterol) can reduce the formation of arterial plaque, thus lowering the risk of heart problems. Additionally, Vitamin E contributes to eye health by shielding the eyes' cells from oxidative damage, potentially reducing the risk of age-related macular degeneration (AMD), a common cause of vision loss in older adults. Furthermore, emerging research suggests that Vitamin E may have a protective effect on cognitive function and help reduce the risk of cognitive decline. Overall, Vitamin E's antioxidant activity and various health benefits make it a valuable nutrient for maintaining overall well-being.
Are the capsules easy to swallow?
Yes. Very. D3 Complete comes in small, softgel capsules that are easy to swallow for most people. They have a smooth coating and are designed to go down easily, even if you typically have trouble with pills. For extra comfort, you can also take them with food or a glass of water.
Why did you only make 1000 IU of Vitamin D3?
The recommended daily intake of vitamin D3 can vary depending on individual needs.
Our 1000 IU softgels are designed to offer flexibility, allowing customers to adjust their intake according to their specific health goals.
For some individuals, taking a single 1000 IU softgel may be sufficient to meet their needs. However, others may choose to take additional capsules to supplement their vitamin D3 intake. This flexibility enables customers to tailor their supplementation based on their personal requirements and preferences.

What is the Stronger Bones For Life guarantee?
Your Stronger Bones For Life Guarantee. You need strong bones for the rest of your life to enjoy rather than endure your golden years. With our guarantee, you can continue enjoying your favorite activities for the rest of your days.
Measurable improvements will appear at 6 months from when you start your AlgaeCal Plus and Strontium Boost program. You may choose to wait for your next scheduled scan so that it is paid for by your insurance, or you may choose to pay out of pocket to check your results earlier. Either way is fine.
IMPORTANT: Your 3 Steps to Guaranteed Bone Density Increases
1. Have a DEXA scan that is not more than 30 days old to establish a baseline measurement. (If you had a DEXA scan more than 30 days ago, your guaranteed period will launch from your next scan onward. So don’t wait! Start building healthy new bones right now, before your guarantee begins!
2. Take AlgaeCal Plus and Strontium Boost at full dose as directed for a minimum of six months, or until your next DEXA scan. It doesn’t matter if it’s six, twelve, or even twenty-four months after you start - so long as you have continued to take your products at the full dose between scans.
3. Get your follow-up DEXA scan from the same clinic as your previous scan, and ideally, on the same machine, too. That way, every scan is directly comparable to the last.
If your follow up scan does not show an increase in either hip or spine bone density, we will refund every penny you spent on AlgaeCal Plus and Strontium Boost between those two DEXA scans.
