Drug Interactions

Will AlgaeCal Interfere with my medication(s)?

Some medications and supplements require separation from AlgaeCal Plus to limit any potential interactions. For example, thyroid medication, antacids, and certain antibiotics should be taken at least 4 hours from AlgaeCal Plus. Iron supplements also should be separated correctly.

If you take a standalone iron supplement, please take it 2 hours from AlgaeCal Plus to avoid decreased absorption. If your iron comes from a multivitamin, you do not need to separate it from AlgaeCal Plus.

Vitamin K2, including the vitamin K2 in AlgaeCal Plus, may interfere with certain anticoagulant drugs and should be avoided unless otherwise directed by a physician.

For general guidelines about how to take AlgaeCal, please reach out to our Bone Health Consultants at [email protected] or by calling 1-800-820-0184. Always check with your doctor for details about possible interactions between AlgaeCal products and your medications.

Ingredients

The “Plus” in AlgaeCal Plus

Calcium 720 mg
(As AlgaeCal® L. Superpositum)
AlgaeCal is a unique calcium that contains all 13 essential bone-building minerals. Studies show these plant-based nutrients can stop bone loss – and even increase your bone density.
Magnesium 350 mg
(As Magnesium Oxide & AlgaeCal® L. Superpositum )
If you want better bones, then you need more magnesium. Clinical studies show people with healthy magnesium levels have better bone density than their magnesium-deficient counterparts.
Vitamin D3 1600 IU
(As Cholecalciferol)
Vitamin D is vital for your bone health. Without this essential nutrient, your body can’t absorb calcium, and that’s bad news for your bones. But don’t worry – every serving of AlgaeCal Plus has a generous 1,600 IU of this bone-building vitamin.
Vitamin K 100 mcg
(As K2 VITAL™ MK-7)
You need vitamin K2 because it collects calcium from your bloodstream and directs it into your bones - keeping them healthy and strong. You don’t want calcium getting into your soft tissue - where it can cause heart attacks, strokes, and even Alzheimer’s.

K2VITAL™ is a trademark of Balchem Corporation or its subsidiaries.
Boron 3.0 mg*
(As Boron Glycinate)
This essential nutrient helps your bones get the calcium, magnesium, and vitamin D they need to stay healthy and strong. It also helps your body make collagen, the main protein that holds your bone together.
Vitamin C 50mg
(As Calcium Ascorbate)
Vitamin C helps your body fight the root cause of bone loss. A 17-year study found that a high intake of this vitamin reduced the likelihood of hip and non-vertebral fractures.
Potassium Trace
(As AlgaeCal® L. Superpositum)
By helping to neutralize the acidic pH resulting from the Standard American Diet, potassium prevents the loss of calcium from bone to restore a more alkaline pH, thus conserving calcium within our bones and reducing its loss in urine.
Copper Trace
(As AlgaeCal® L. Superpositum)
Copper is essential in bone metabolism, activating enzymes like lysyl oxidase that incorporate both collagen and elastin into the organic component of bone.
Manganese Trace
(As AlgaeCal® L. Superpositum)
Manganese is critical in the formation of the extracellular matrix–the ground substance to which collagen adheres, and for the development of chondrocytes, the cells that secrete cartilage and become bone building- osteoblasts and eventually osteocytes, which regulate the entire bone renewal process. Without manganese, bone mineralization simply cannot start!
Silicon Trace
(As AlgaeCal® L. Superpositum)
Silicon plays a key role in bone formation by stimulating the production of bone-building osteoblasts and the synthesis of type 1 collagen, and by increasing calcium’s incorporation into bone.
Nickel Trace
(As AlgaeCal® L. Superpositum)
Nickel can affect the distribution of other nutrients in your body, including calcium. Given the obvious benefit calcium has on our bones, you can see why an adequate level of nickel is critical to maintaining healthy bone!
Phosphorus Trace
(As AlgaeCal® L. Superpositum)
Approximately 85% of the body’s phosphorus is found in your bones. It’s fundamental to growth, maintenance, and is necessary along with calcium and magnesium for proper growth and formation of bones.
Selenium Trace
(As AlgaeCal® L. Superpositum)
Selenium is the required cofactor for two groups of enzymes intimately tied to bone health: the selenoenzymes, which neutralize bone-destructive free radicals and the deiodinase enzymes, which are necessary for the healthy thyroid function that keeps our bone renewal metabolism running. For these reasons, low selenium can mean decreased bone mineral density.
Vanadium Trace
(As AlgaeCal® L. Superpositum)
In one study, vanadium compounds were shown to increase bone formation without any adverse health effects!
Zinc Trace
(As AlgaeCal® L. Superpositum)
Zinc is an essential mineral that plays a crucial role in bone metabolism by acting as a cofactor for specific enzymes. But that’s not all - studies have found that zinc can also help prevent bone loss, making it a vital nutrient for both men and women, especially those in their post-menopausal years.

Frequently Asked Questions

  • What is AlgaeCal Plus?

    AlgaeCal is a South American marine algae species, Lithothamnium superpositum (or Algas calcareas as the locals call it). This kiwi-fruit sized algae is sustainably hand harvested in the atlantic ocean, sun dried, then milled into a powder. There is no extraction process or additives used – just pure whole food calcium and minerals coming from a living plant. Watch the AlgaeCal Harvesting video here. AlgaeCal powder is the foundational ingredient in our products, AlgaeCal and AlgaeCal Plus. AlgaeCal powder has significant advantages over traditional calcium supplements that are pure calcium because AlgaeCal contains all 13 known essential bone supporting minerals: calcium, magnesium, manganese, phosphorous, nickel, silica, copper, vanadium, potassium, zinc, boron, selenium and strontium. Traditional calcium carbonate and calcium citrate supplements are made from limestone and marble – and your body does not absorb rocks very well – so plant-sourced AlgaeCal has the benefit of being body-friendly and better absorbed into your bones. In fact the superfood mineral combination naturally found in AlgaeCal has been clinically supported to increase bone density in adults – but traditional calcium supplements only slow annual bone loss a little. In other words, after age 40, we typically lose 1% of our bone density every year until death – so most will become osteoporotic if they live long enough. Traditional calcium supplements slow this annual bone loss from 1% to ¾% – so it only helps a little. But AlgaeCal Plus actually increases bone density – and if taken with Strontium Boost, the combination is even more effective at increasing 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.

    For more information on scheduling your AlgaeCal supplements with meals –– and any prescription medication or supplements you’re currently taking –– click here.

  • What ingredients are in AlgaeCal Plus?

    AlgaeCal Plus contains calcium from a marine, plant-based algae source called Lithothamnion superpositum. This algae belongs to the family of algaes known as Algas calcareas. So to make it easier to say, we just named it “AlgaeCal”! AlgaeCal has worldwide exclusive rights to this particular type of algae – and it is the only clinically backed calcium supplement in the world with human studies showing increases in bone mineral density. All other calcium has only ever been shown to slow down bone loss. In addition to this unique calcium, AlgaeCal Plus also contains magnesium, vitamin D3, vitamin K2 (in the form MK-7), vitamin C, boron and naturally-occurring trace minerals. In particular, AlgaeCal Plus contains all 13 bone-building minerals in their proper proportions that make up your bone matrix. AlgaeCal Plus is also dairy-free, soy-free, gluten-free and non-GMO! For an in-depth explanation of each ingredient go to AlgaeCal Ingredients.

  • Do I have to take both AlgaeCal and Strontium Boost?

    If you are suffering from bone loss, it is best to take both AlgaeCal Plus and Strontium Boost. Together they are clinically supported to increase bone density in as little as 6 months – at any age! They also increase your bone density at a faster rate than AlgaeCal Plus alone. For example, studies prove AlgaeCal Plus alone can increase bone density by an average of 1.3% per year, compared with an average bone density increase of about 4% per year with AlgaeCal Plus and Strontium Boost together. This is significant for those suffering from bone loss who may be experiencing more than 1% bone density loss per year. Taking the two together also gives the bone-building process a “kick start” to increase bone density safely and naturally, ensuring you have covered any potential losses.

  • How much elemental calcium is in AlgaeCal Plus?

    AlgaeCal lists the minerals in the elemental form on the supplement facts label. Therefore, AlgaeCal Plus contains 360 mg of elemental calcium in two capsules (that’s 720 mg of elemental calcium in a daily dose, AlgaeCal lists the minerals in the elemental form on the supplement facts label. Therefore, AlgaeCal Plus contains 360 mg of elemental calcium in two capsules (that’s 720 mg of elemental calcium in a daily dose, 4 capsules).

  • I have trouble swallowing pills. How big are the capsules? Is it OK to open the capsules and mix it with food/beverages?

    AlgaeCal Plus, AlgaeCal Basic, and Strontium Boost all use soft capsules which are ¾” long and easy to swallow. If you do have trouble swallowing them, the two-part capsules can be pulled apart. You can then sprinkle the tasteless powder into your favorite drinks and food. We recommend semi-solid foods such as smoothies, applesauce or yogurt and avoiding hot drinks as temperatures above 120 degrees Fahrenheit as it may reduce the potency of the vitamins C, D, and K2. Please note that the AlgaeCal powder is only partially water soluble due to the many natural minerals and therefore does not dissolve completely in liquid.

  • Does AlgaeCal Plus cause side effects such as deposits in kidneys or arteries?

    The vast majority of people who experience gastrointestinal side effects from regular calcium supplements have not experienced any adverse side effects from AlgaeCal. These stomach troubles usually derive from consuming rock-source calcium, which our bodies are not designed to digest. Plant calcium contains a variety of balancing minerals including magnesium, which make it more easily digested. We recommend that you split your daily dose into breakfast and dinner time. Taking AlgaeCal with food increases absorption and reduces chances of any gastrointestinal issues.

  • Does AlgaeCal Plus cause constipation, gas or bloating?

    The vast majority of people who experience gastrointestinal side effects from regular calcium supplements have not experienced any adverse side effects from AlgaeCal. These stomach troubles usually derive from consuming rock-source calcium, which our bodies are not designed to digest. Plant calcium contains a variety of balancing minerals including magnesium, which make it more easily digested. We recommend that you split your daily dose into breakfast and dinner time. Taking AlgaeCal with food increases absorption and reduces chances of any gastrointestinal issues.

  • I am petite, so do I need a full dose?

    The recommended daily dose is the same for each individual no matter their size because it is based on age, not weight. In fact, if you are petite, you are at a higher risk for bone density loss because you have less skeletal mass to begin with, so a full dose is recommended.

  • Is AlgaeCal Plus tested for contaminants? Does AlgaeCal contain Lead and other Heavy Metals?

    Great question! Actually, lead is a natural mineral like calcium or magnesium which is found in the earth, air and water. So every vegetable that grows in the soil or water has normal amounts of lead in it – the marine algae in AlgaeCal is no exception. Luckily, our bodies easily clear normal amounts of lead daily through urine, feces, and sweat.

    Every batch of AlgaeCal powder is tested by a third party laboratory for microbial activity, heavy metals, mineral content and more. The final product is made in an FDA-inspected GMP (Good Manufacturing Practice) plant where the highest standards are kept.

    AlgaeCal has FDA registration and Health Canada approvals. It has been on the market for 20 years and has 3 clinical studies and a toxicology study showing extraordinary safety!

  • Can I take AlgaeCal Plus if I am on bone medications?

    Absolutely.  All bone drugs require calcium supplementation to supply the needed calcium for bone building – and AlgaeCal Plus is the highest quality calcium available.

  • Can I take AlgaeCal Plus with my prescription medication?

    As a general rule of thumb, it is best to separate any prescription medication by at least 2-3 hours from when you take AlgaeCal Plus or Strontium Boost. This will help limit any potential interactions and ensure you receive maximum absorption from both your medications and supplements. However, some medications are recommended 3-4 hours apart. Please confirm with your doctor for your unique case. If you happen to be on an older anticoagulant prescription drug (blood thinner), vitamin K2 is not recommended. However, there are two newer types of anticoagulant drugs on the market called the XA Inhibitors and the Direct Thrombin Inhibitors. Ask your doctor about switching to one of these newer anticoagulants as the older ones are detrimental to your bone health – as they completely block the usage of vitamin K2 (the older anticoagulants use the same pathway of absorption as vitamin K2 so they cancel each other out). The newer types of anticoagulant don’t interact with vitamin K2 as they use different pathways for absorption in your body. As an extra precaution, please confirm any supplement or medication interaction with your doctor or physician before use.

  • If AlgaeCal Plus is so good why doesn’t my doctor know about it?

    An increasing number of doctors are aware of the significant science supporting AlgaeCal products and are referring their patients to them.  It is extremely difficult for doctors to keep up with the flood of new studies being reported in the journals. If you would like to provide your doctor with the science backed information on AlgaeCal, please refer to our Research Page. In addition, we also offer a convenient, one-page printout that you can take to your doctor: Take It To Your Doctor PDF.

  • Should I be concerned with the iodine level if I have a thyroid issue?

    AlgaeCal does contain a minute amount of iodine – but only 160 mcg of iodine per daily serving of AlgaeCal Plus. If in doubt, please discuss with your doctor whether the amounts in AlgaeCal are appropriate for you. Additionally, we have customers taking thyroid-specific medication who see increases in their bone density with the AlgaeCal program. For best results, we recommend that you separate your thyroid medication by at least 4 hours from when you take AlgaeCal or Strontium Boost.

  • Can I take AlgaeCal Plus if I have a shellfish allergy?

    AlgaeCal Plus does not contain any shellfish – only calcium, minerals from organic algae and added vitamins. Many of our customers have shellfish allergies and take AlgaeCal safely with no adverse reactions. That being said, for any severe allergies we do advise consulting with your doctor/allergist for their best recommendation.

  • Is AlgaeCal FDA approved?

    The US Food and Drug Administration (FDA) only approves medications. Since AlgaeCal is a completely natural supplement, it’s simply not possible for AlgaeCal to have FDA approval. In saying that, AlgaeCal is registered with the FDA under GRAS status (Generally Recognized as Safe). GRAS status means a food ingredient is deemed safe by a qualified panel of experts.

  • Is AlgaeCal Plus Vegan?

    While AlgaeCal Plus and AlgaeCal are vegetarian, they aren't considered vegan because the vitamin D3 is sourced from lanolin, which is sheep's wool wax, so they are still considered an animal by product

  • Is AlgaeCal Plus gluten-free / soy-free?

    AlgaeCal Plus is soy-free, gluten-free, dairy-free and non-GMO.

  • Is AlgaeCal Heat Sensitive?

    All AlgaeCal products undergo stability testing where they are exposed to a variety of environmental factors such as light, humidity and extreme temperatures to establish its shelf life. In other words, there is no cause for concern when it comes to temperatures found in our product warehouse, during shipping to you, or in your home. Please note: stability testing is used to determine storage shelf life. We do not recommend you put AlgaeCal powder in hot drinks above 120 degrees Fahrenheit, as it may reduce the potency of vitamins D, C and K. Instead, pull apart the AlgaeCal Plus capsules and add the powder to cold or room temperature drinks or foods like smoothies and yogurt for best results.

  • Why does AlgaeCal Plus use magnesium oxide?

    AlgaeCal Plus contains naturally-occurring magnesium from the algae, plus additional magnesium oxide for an optimal 2:1 calcium to magnesium ratio. This ratio is the same ratio that is found in your body and has been clinically supported in human studies. Research shows magnesium oxide is as effective, if not more, than other forms of magnesium at maintaining and restoring magnesium in your bones and cells. For an in-depth explanation of why we chose this superior form, go here.

  • Will AlgaeCal Plus help with osteoarthritis?

    Anecdotal evidence suggests AlgaeCal Plus may help reduce pain and stiffness, while improving range of motion. Boron, one of AlgaeCal Plus’s key ingredients, has also been shown to decrease inflammation in osteoarthritis. Although many people suffering from osteoarthritis have reported relief with the AlgaeCal program, our published and peer-reviewed studies found here have been conducted to measure increases in bone density, specifically. There have not been any peer-reviewed studies conducted on AlgaeCal Plus and osteoarthritis. We recommend targeting arthritic inflammation through exercise, sleep, an anti-inflammatory diet, and our very own natural anti-inflammatory Triple Power Fish Oil! Triple Power’s formulation provides anti-inflammatory and antioxidant ingredients, shown to help manage joint pain and stiffness. Learn more about osteoarthritis and 5 natural remedies you can count on here.

  • Will AlgaeCal Plus help with rheumatoid arthritis?

    AlgaeCal Plus may help reduce pain and stiffness, while improving range of motion. Patients with rheumatoid arthritis are commonly deficient in vitamin C, vitamin D, calcium, magnesium, zinc, and selenium — all of which are found in our AlgaeCal Plus formulation. Although many people suffering from rheumatoid arthritis have reported relief with the AlgaeCal program, our published and peer-reviewed studies found here have been conducted to measure increases in bone density, specifically. There have not been any peer-reviewed studies conducted on AlgaeCal Plus and rheumatoid arthritis. 1 in 4 people with rheumatoid arthritis will also develop bone loss, and for them, Strontium Boost is recommended to complement AlgaeCal Plus for preventing excessive bone loss. Together the pair have been shown to triple the rate of bone building in a single year. Learn more by checking out the Bone Builder Pack here. We recommend targeting arthritic inflammation through exercise, sleep, an anti-inflammatory diet, and our very own natural anti-inflammatory Triple Power Fish Oil! Triple Power’s formulation provides anti-inflammatory and antioxidant ingredients, shown to help manage the pain and stiffness associated with arthritic conditions.
