Maybe you’ve heard that more people have calcium deficiency than not. So now you’re ready to get down to brass tacks and figure out how you can be among the minority of people who are getting all the calcium they need.

Smart move — especially considering that one study suggests as much as 68% of the American population suffers from calcium deficiency1.

Considering calcium is arguably the most important nutrient in your body, this is alarming and problematic.

More than 99% of your calcium is stored in your bones and your teeth, which supports skeletal function and structure. 

The rest of the calcium in your body is used for other critical functions such as:

  • muscle contraction 
  • hormone secretion
  • blood vessel contraction and expansion 
  • sending messages through the nervous system
  • activating the enzymes involved in glycogen metabolism
  • activating a number of the vitamin D-dependent hormones clotting factors

What Happens When Your Calcium Levels Are Low

In fact, calcium is so important your body will pull a Bonnie and Clyde on you and steal it to beef up the supply. You see, if your body doesn’t get enough calcium to keep its base functions running smoothly, it will leach calcium from your bones to make up for the shortfall (yikes!).

If this goes on for long enough, your bone mineral density will deplete to the point of developing disorders like:

Osteopenia

Bone loss or bone thinning beyond the normal range is known as osteopenia. It’s a precursor to osteoporosis and is officially marked with a T-score between -1 and -2.49. T-scores are calculated as a part of DEXA scans, which measure bone mineral density.

Osteoporosis

Excessive bone density loss resulting in a T-score of -2.5 or lower is categorized as osteoporosis. Bones become weak and brittle and put you at an increased risk of fracture.

Both osteopenia and osteoporosis are signs of calcium deficiency disease.

The FDA states that “Adequate calcium and vitamin D throughout life, as part of a well-balanced diet, may reduce the risk of osteoporosis.”

What Is Hypocalcemia?

Calcium deficiency disease, known as hypocalcemia, can develop when the blood has low levels of calcium. Unfortunately, it has become a global health problem. People around the world are simply not getting enough calcium from their diets.

What Causes a Calcium Deficiency?

As you know, calcium deficiency doesn’t happen overnight. It creeps in and snatches calcium as you go about your business. Left undetected, it’ll do this for years. But you’re on to that fiend. You even know its root causes, so you’re ahead of the game. Right? Well, if a reminder wouldn’t hurt, here are the causes to keep in mind:

Age

Infants and children absorb as much as 60% of the calcium they consume2. But once you reach adulthood, your absorption slowly decreases to about 25%.

Lack of Calcium

This is a bit of an obvious one, but low calcium intake over a long period of time is a primary cause of calcium deficiency. It’s recommended that adults over the age of 19 consume between 1,000–1,200 mg every day, depending on your gender.

Prescription Medications

Certain medications can interfere with your body’s ability to absorb nutrients. And they may decrease calcium absorption3. For a more thorough look at drugs that can cause bone loss, check out our article on the top 12 prescription drugs that cause osteoporosis.

Hormonal Changes

A decline in estrogen during menopause causes women to lose bone density more rapidly. Postmenopausal women have about one-tenth of the estrogen levels that premenopausal women have. Genetic factors, dietary intolerance, and malabsorption can also contribute to calcium deficiency. Since calcium is so critical throughout the body, low calcium symptoms can show up anywhere. And they can manifest in many different ways.

Malabsorption

Calcium absorption refers to the amount of calcium absorbed from the digestive tract into your body’s circulatory system. Another term for this is calcium bioavailability. Calcium absorption can be affected by the amount of calcium in your body, your vitamin D, and K2 levels, your magnesium and trace mineral status, age, pregnancy, and even certain plant substances in your diet. The amount of calcium consumed at a time can also affect absorption. For example, the efficiency of calcium absorption decreases as the amount of calcium you consume at a meal increases.

Vitamin D

Calcium and vitamin D work really well together. When you take vitamin D, you increase your body’s ability to absorb calcium effectively. Lara Pizzorno, the author of Your Bones, says, “Less widely known is that vitamin D also boosts the expression of the vitamin K-dependent proteins. So when you take supplemental vitamin D, you are increasing the amount of calcium available in your body and, therefore, your need for vitamin K.” In other words, vitamin D increases the amount of calcium you absorb, but in turn, also increases your need for vitamin K.

Vitamin K2

Don’t mix this up with vitamin K1. Vitamin K2 has nothing to do with blood clotting factors. And it’s very difficult to get without supplementation. It’s not in leafy greens like K1 and is found only in tiny amounts in eggs and cheeses. Its main role is to regulate calcium deposition. Meaning, vitamin K2 cleans calcium deposits from your arteries and moves it to your bones.

Magnesium

It’s reported that as many as 80% of Americans are magnesium-deficient! Deficiency of this mineral affects bone building, bone fragility, and alters calcium metabolism and the hormones that regulate calcium.

What Are Some Signs of Calcium Deficiency?

Want in on a little secret? Okay — lean in. Your body’s a snitch. That’s right. It’ll tell your business in a minute. Hungry? Your tummy grumbles. Tired? Your mouth yawns. Your body constantly sends you signals to clue you in on what’s happening inside. And when it comes to calcium deficiency, your body sends a host of warning signs. If left untreated, calcium deficiency symptoms in adults will vary from mild to severe.

Minor symptoms can include:

  • Numbness
  • Tingling fingers
  • Muscle cramps
  • Lethargy
  • Poor appetite
  • Weak or brittle fingernails
  • Difficulty swallowing
  • Fainting

More severe symptoms can include:

  • Mental confusion, irritability, depression, and anxiety
  • Tooth decay
  • Insufficient blood clotting
  • Bone fractures
  • Osteopenia or osteoporosis
  • Growth and development delays in children
  • Heart problems involving blood pressure and heart rhythms

So all these signs are nice to know, but they still don’t tell you if you have a calcium deficiency. Talk to your doctor about testing your calcium levels so you’ll have an idea of how much more you need. Armed with that info, you’ll be a step closer to serving an eviction notice on calcium deficiency.

How Is Calcium Deficiency Diagnosed?

Considering many calcium deficiency signs are obvious, your doctor will first make a clinical assessment of any symptoms, such as:

Next, your doctor will look at your blood work to check your calcium, vitamin D, and parathyroid levels. 

Hey, no one likes needles. But if you want to let calcium deficiency know its days of breaking bones and taking names are over, roll up that sleeve. When that’s over, your doctor will get into the less-than-sexy stuff and ask about your medical history. Hereditary conditions can play a role in developing Hypocalcemia and osteoporosis. They may also recommend a DEXA scan to assess your bone mineral density.

How to Prevent and Address Calcium Deficiency

Now if all this talk about calcium deficiency makes you wish you could time travel back to your 20s, don’t despair. It’s not difficult to raise your calcium level. 

Generally it involves adding more calcium to your diet. But your calcium deficiency treatment plan will ultimately depend on the severity of your deficiency. So it should be discussed with your doctor.

As far as prevention goes, it’s never too early to start. Focus on eating calcium-rich foods with plenty of bone-friendly nutrients. And definitely check out the recipe section of our blog for quick, easy, and delicious bone-healthy recipes the whole family can enjoy. 

Beans

And if you’re really serious about kicking calcium deficiency to the curb, take a daily calcium supplement like AlgaeCal Plus. It’s a plant-based calcium that naturally contains all 13 essential bone-building nutrients. AlgaeCal Plus is specially formulated with magnesium, vitamin D3, vitamin K2, and boron. As you may know, vitamin D3 enables our active absorption of calcium (which accounts for 85% of the calcium we absorb). And magnesium helps the body properly absorb and utilize calcium and vitamin D. Moreover, vitamin K2 activates the enzymes that usher calcium into our bones and keep it out of our arteries. And boron optimizes the use of the estrogen women still produce after menopause.

So when combined with Strontium Boost, AlgaeCal Plus skyrockets your bone-building potential to the next level. Both are formulated to work together perfectly as a team to increase bone density, year after year. Basically, it’s like time travel in a bottle — well, at least for your bones.

    Hi Nadia,

    Thank you for taking the time to comment! You’re absolutely correct; most women reach peak bone mass by the age 30. We are referring to the next stage in bone health – where around the age of 40, we start to lose 1% of our bone density each year.

    We appreciate you bringing this to our attention, we can definitely see how the way it was written may have been confusing, and we will make sure that is corrected. Please let us know if you have any questions!

    Hi Karen,

    Good question. The majority of calcium supplements are rock-based, so it’s no wonder they are not well tolerated and can cause stomach irritation! AlgaeCal is different. It does not cause an upset stomach because it is plant-based calcium, so our body recognizes it as food, similar to broccoli, spinach, and other leafy greens.

    If you’d like to learn more about the difference between rock-based & plant-based calcium, check out this blog post: https://blog.algaecal.com/plant-based-calcium/.

    Hi Juliet,

    Good question! While you can take AlgaeCal on an empty stomach, we recommend taking it with food for the best results. Having food in your stomach helps to stimulate stomach acid production and increase solubility. For more information about how to take AlgaeCal go here.

    We hope that helps!

    Hi Monica,
    A well written article. Thank you. I ve been using Algae Cal and the Strontium Citrate you all sell as well for the past six months. I hope to see increases.

    Regarding Parathyroid Hormone having too much cause depletion of bones as well. I had two parathyroid tumors removed in 2015. Tumors produce too much hormone and cause bone destruction. Good thing is we have four parathyroid glands and when two bad ones were removed the sleeping one wakes up and produces just the right amount of hormone.
    I was always supplementing calcium since age 30 and still saw bone density decrease. Now that tumerous glands removed I have seen increase in hips two years later. Dr Norman in Florida has a great website parathyroid.com which has great video education and pages of twenty years of data. Fourth year after surgery is critical for me as that will max time for
    Bone building with supplements and if my -3’lower Back has not improved I may have to get prescription from doctor. I am trying to keep my Algae Cal supplement regime and exercise too. Thank You Again for communication it helps alot!

    In looking at my bone density report, there is a T score and a Z score. The T score compares to 20 and 30 year olds while the Z score compares to people closer to my age. I am 66 so being compared to 20-30 year olds—-I don’t see the point. I have ordered my algaecal and I am hoping I can get better scores on my next scan.

    Hi Skyring,

    Great question! We do provide some of our raw material for other companies to use in their own formulations, including Garden of Life.

    Although many of these formulations will have a similar makeup, including things like vitamin D3 and K2 along with their own blends of fruit and vegetable extracts; AlgaeCal’s proprietary blend of vitamins and minerals combined with our unique algae, make AlgaeCal the only calcium supplement on the market that has been supported time and time again to show a measured increase in bone density! We have 3 human clinical studies that have all been peer-reviewed and published in respected journals, and you can find them all here.

    In contrast, other calciums may simply slow down the rate of bone density loss. AlgaeCal is also the only calcium supplement guaranteed to increase bone density. You can learn about our guarantees here.

    Hopefully this helps in your research! If you have any further questions or concerns, you can always email us at [email protected] or call to speak with one of our Bone Health Consultants at 1-800-820-0184 🙂

  20. Jenna AlgaeCal

    July 16, 2018 , 3:22 pm

    Hi Janice,

    Changes in bone mineral density are based on before and after DXA scan (bone density scan) results.

    We recommend looking for a functional doctor through The Institute for Functional Medicine for an IFM certified practitioner in your area here – these are doctors who have gone the extra mile to do additional courses and certifications on top of their medical practice.

    You can also reach our Bone Health Consultants by calling 1-800-820-0184 or emailing [email protected]. Hope that helps!

    I was diagnosed with low bone density in my early 50s.(I’m 68 now) I started the AlgaeCal about 2 years ago. This supplement along with a better diet and weight training resulted in me going from -3.5 score to -2.4!!! My doctor was AMAZED! He was so sure that I was just going to get worse. Will never be without AlgeCal!

    Can you still take this algaecal with regular multi vitamin daily?

  25. Jenna AlgaeCal

    October 23, 2018 , 11:33 am

    Hi Karla,

    Yes, you can! But there are a couple things to keep in mind:
    • You’re getting all of the vitamins and minerals your bones need from AlgaeCal Plus and Strontium Boost. But you can still take a multivitamin if you’d like — just make sure it contains less than 300 mg of calcium (since you’re getting all the calcium you need from AlgaeCal and your daily diet).
    • A general rule of thumb is to take any other supplements containing calcium, magnesium, iron or zinc 2 to 3 hours before or after your AlgaeCal. This will help limit any potential interactions and ensure you receive maximum absorption from all your supplements.

    For more information on how to take AlgaeCal check out this post.

    Thanks for reaching out, Biju! So sorry to hear about your ongoing symptoms. It’s best to work with your doctor to determine what’s causing this for you as there are many different causes which need to be treated differently. For example, calcium deficiency can be caused by a lack of calcium, malabsorption, parathyroid issues, and more (listed in the article).

    Hopefully this information helps facilitate a discussion with your doctor!

    I just read your body condition today, I think it’s better if you find a doctor in Gastroenterologist specialist, it might be you are not only having calcium deficiency but you might be having nutrients deficiency, coming from the malabsorption of your digestive system. So if you take calcium alone, it might won’t solve your problem, you might need to take vitamins and minerals in high dose for a while. Hopefully you will getting better soon and have a wonderful life

    I have a pain one of my knees, I injured two years ago when I was playing football and I linked a doctor and he told me that I have meniscus injury and he gave me some injections and tables which remove all pains and swellings at that time.
    After I awhile, about year later I try to play again then I feel a pain like before when I try to kick the ball or suddenly change direction ( during running), when I rest about a minute the pain go out.
    I’m in somalia and we don’t have a specialist doctor in here, so what can you recommended me to do naturally, is there any diets/food or any natural remedies that restore my meniscus.
    Sorry my broken English.

    Thanks Jenna.

  36. Jenna AlgaeCal

    May 14, 2019 , 9:12 am

    So sorry to hear this, Nasir — that sounds very uncomfortable.

    The meniscus is made of cartilage, and AlgaeCal has been studied specifically for bone mineral density, not cartilage. However, there are nutrients that are important for both bone and cartilage development. For instance, protein and amino acids (often called the building blocks of protein) contribute to both cartilage and bone cells. And silicon is also needed by both. AlgaeCal Plus specifically contains 25.94 mg of silicon in the daily dose (4 capsules) which is significant for bone health — so it may be helpful for you.

    Hopefully that helps!

    Hi Husna,

    I’m sorry to hear about the back pain you’re experiencing. It’s important to first discover the underlying cause to this pain — have you had a chance to work with a functional doctor? We recommend looking for a functional doctor through “The Institute for Functional Medicine” and look for ones in your area that are IFM Certified Practitioners.

    Practitioners who go through the entire IFM certification process are truly dedicated – it takes a couple of years to complete, many in-person 4-5 day seminars, at least 1,000 hours of study, and a certification exam that rivals the exams docs take to get their medical license, plus the cost is high, both in terms of time spent and conference and seminar fees. And the doctors are doing this in addition to their medical practice! True dedication to providing the best care.

    Hi. My 2 sons, now 13 and 7, both have been having severe growing leg pain when they were younger. My youngest still does once in a while. Over all these years, I have observed that anytime I tried to give them high quality Vit D3, they both would have their growing leg pain, even though they are always on the low average in their vit D blood tests. So this made me almost impossible to supplement them with D3 during the winter. My eldest at such terrible pain, especially evenings and night, that I consulted with him Pediatric Ortopedists + lots of integrative/functional medicine Doctors. No one has a clue and we were dismissed so many times: not a big problem for the kid, just give him an ibuprofen (like 5 days a week? Really). I have observed that supplementing them with Magnesium has been reducing the frequency, but does not avoid the problem all completely. If taken early in the pain, turmeric would work and calm b4 the pain would be too difficult. Nevertheless, not a single doctor was able to give us the slightest idea. Only my own observations helped a bit, but I’m still looking out for solutions, as I realized I do too can’t take too much Vit D. Indeed, I realize I do too get some pain in the legs if I take vit D3.
    My guts are telling me there is somethong related with minerals deficiency. Our nails are always brittle since we all take magnesium each night. So I wonder. Not very much attention is brought for this subject, whereas I hear lots of parents getting some similar concerns. Just wondering if you’re able to connect some dots for me.

    Hi Mathilde,

    Thank you so much for reaching out and sharing your story with us. I reached out to Lara Pizzorno, Bone Health Expert and author of Your Bones, for her best suggestions:

    It sounds like this family’s genetics predispose them to osteomalacia due to vitamin D insufficiency, but supplemental vitamin D does not help.

    My guess is that this is because of genetic issues that affect their ability to metabolize and utilize vitamin D, possibly because it is being taken as a capsule, which is what I hope is the case because that’s an easy fix.

    In brief, I suggest they try taking their vitamin D in sublingual form to see if this helps. And please ask if they will keep us posted on how they are doing!

    Here is my reasoning for this suggestion:

    Osteomalacia, which typically presents as bone pain and muscle weakness, occurs when newly formed bone is not mineralized in time during modeling (bone formation) in children, or when existing bone is replaced by unmineralized bone matrix (osteoid) during remodeling in children and adults. The main causes of this defective mineralization are a lack of needed minerals (primarily calcium). Calcium insufficiency results from insufficient dietary intake or insufficient sun exposure (not sure where this family lives or if they don’t get sun exposure because of sunscreen and clothing that covers too much skin) or lack of supplemental vitamin D, which as you know is required for our active absorption of calcium in the intestines.

    In this instance, vitamin D levels are low, but vitamin D supplements have not been helpful.

    One potential reason for this is that the genetic inheritance of this mother and her sons includes slow, less effective versions of the enzymes that convert D3 to 25(OH)D and then those that convert 25(OH)D to 1,25-D. They may also have inherited poorly formed vitamin D receptors, so the 1,25-D they do manage to produce does not bind well to cells, which is what initiates all vitamin D’s beneficial actions, including calcium absorption.

    When vitamin D is taken in capsule form, it will be sent from the digestive tract into the portal vein and delivered to the liver, where it will be processed by liver enzymes before it gets out into the systemic circulation.

    The liver is the primary place in the body where D3 is supposed to be converted to 25(OH)D, but enzymes that make this conversion are present in cells all over the body.

    If the liver enzymes are ineffective, and D3 is taken in capsule form, this conversion will not take place effectively. And that means that little 25(OH)D will be sent into the bloodstream and flow through the kidneys, which is the primary place where the enzymes that convert 25(OH)D to 1,25-D, the active hormonal form of vitamin D that is the only form in which this nutrient helps us absorb calcium, is produced.

    Again, the enzymes in the kidney that do this job are found in far smaller amounts in cells throughout the body, although the kidney is the primary place where this conversion occurs.

    Also, other enzymes in the liver and kidneys have the job of clearing out vitamin D. It’s also possible that this family’s genetic inheritance includes fast versions of these – that would also greatly impair their ability to maintain optimal levels of vitamin D and to absorb and utilize calcium.

    I have five suggestions:

    Try taking sublingual vitamin D – here’s a link to the product we use and recommend: https://www.bioticsresearch.com/node/1570 Each drop provides 2,000 IU of D3. If they are taking AlgaeCal Plus, which is HIGHLY recommend since they need everything it contains, including the trace minerals, which are very important, they will be getting 1,600 IU of D3 daily from that (but in capsule form). Still, to err on the side of safety, I suggest they take just 2 drops of sublingual D3 for 2 months and then retest their 25(OH)D levels. This is the easiest, least expensive thing to try and may completely fix the problem.

    In addition to AlgaeCal Plus, they should be using Strontium Boost because strontium boosts calcium absorption, primarily due to its effects on the Calcium-sensing receptor – they can read about this—and a number of the other ways in which strontium improves healthy bone formation — in my post on strontium here. And, of course, at least 1,200 mg of calcium should be consumed daily – AP will be giving them 720 mg, so at least another 480 mg needs to be provided by their diet.

    Triple Power (TP) should also be taken – 2 TBS daily when pain is present. TP contains a significant dose of the active component in turmeric, which is called curcumin, in highly bioavailable, emulsified form. TP also provides EPA/DHA which are essential both for the resolution of inflammation and for the production of the mesenchymal stem cells that develop into osteoblasts.

    If they have not had their genomic profiles run, I urge them to do so! 23&me is one of the less costly options. They need to not just get the “ancestry” option, but have the full profile run. Once they have their “raw data” file, a number of AI tools are now available that can analyze the results – including our AI system, but we are not yet offering our system to the general public. I hope we will be doing so in 6 months as cost will be low, and it will become accessible to “normal” folks. At the moment, they can work with a doctor trained in genomics who can help them understand their raw data, but it’s expensive. Once they know which of the enzymes involved in vitamin D metabolism and/or the vitamin D receptor are not working well, treatment plans can be optimized.

    Discuss running the following labs with their doctor – these can help identify if osteomalacia is present AND after a few months of treatment, if what is being done is correcting it:

    1) PTH — serum calcium is usually normal in osteomalacia, so PTH is not typically checked, but high PTH is one indication for osteomalacia

    2) ALP in children and Bone ALP in adults, if elevated, indicate possible osteomalacia

    3) Serum 25OHD (if low, suggestive of osteomalacia if other factors are present)

    4) Urinary calcium (if low, suggestive of osteomalacia if other factors are present)

    Presence of the above features in the absence of renal/liver disease suggests a diagnosis of osteomalacia. https://www.ncbi.nlm.nih.gov/pubmed/30654108

    I’ve had leg muscle cramps all my life with a rich calcium diet
    , but when I started taking magnesium and also ate foods rich in phosphorus, they disappeared. I’m also eating more nutrient dense foods and keeping the sugar low (5 mg), which is just health common sense. I’ve also heard about people who just can’t absorb vitamin D3, but in cases like this, it’s good to know doctors have solutions!

    I saw your writing … my son, who is 15 now,
    experienced very painful growing pains when he was 7 years old. Sometimes the pains were so bad it was hard for him to walk. I took him to his pediatrician and she ran bloodwork. It all came back okay. When I asked about xrays she wanted to hold off since he was so young and didn’t want to expose him to the radiation. Less than a week later my son was at wrestling practice and was wrestling and fell to the ground screaming. He couldn’t move. We took him by ambulance to the ER. They took X-rays and he shattered his femur!!! They had to perform an emergency surgery. The orthopedic doctor found a bone cyst on his femur. She told me they don’t know what causes the bone cyst, but it is often found in boys between 7-15 years of age and is found on the major bones (hip, femur, arm, ankle bones). It’s not cancerous, but the bone cyst causes an air pocket in the bone. This air pocket weakens the bone and it’s just a time bomb waiting to happen. It could be something as simple as jumping of a curb that causes this trauma, which leads to the shattered break. The only way to find this bone cyst is by an X-ray or by the result of the trauma break. Please have your sons get checked!!! I never forgave myself for not insisting on the X-rays. If I had done that … he would have just had the surgery to remove the bone cyst. Instead he shattered his femur, had to have surgery to scrape the bone cyst off the bone, had to realign his shattered femur bone & had two metal rods inserted Into his femur to hold his femur bones in place. He was in a wheelchair for 3 months, then a walker, and then months of physical therapy. Then a year later had surgery to remove the rods and had to scrape the bone cyst away again because it started to grow back because they couldn’t get it all the first time due to the trauma of the shattered femur. Then had bone tissue grafted into the bone where the cyst was removed, then it was back to a wheelchair and then a walker. It was over 1 1/2 year process!! Please get your sons checked!!

    We wanted to clarify that we are not doctors or medical professionals and so cannot share medical advice! Having said that, your doctor may want you to take calcium supplements for a month to see if they help. If you don’t eat much calcium in your diet, it can be a good idea to take a calcium supplement regularly to help you meet your daily requirements.

    Hello! I have been taking AlgaeCal Plus+Strontium Boost for several months and have recently seen on YouTube an article by Ken D. Barry that Calcium is harmful to your health. Calcium can cause heart issues etc. He advises to throw out the Calcium and suggests taking a Vit. D supplement instead. He also recommends weight bearing exercises. What should I do? Thank you!

  61. Megan AlgaeCal

    December 5, 2019 , 1:42 pm

    Hi Sara, thanks for reaching out with your concerns!

    Mr. Barry is right – when it comes to traditional calcium supplements. See, the majority of calcium supplements provide only calcium or calcium + vitamin D, which is why they were found to increase the risk of stroke in some studies. You want to look for a calcium supplement that provides all the necessary bone-building vitamins and minerals, including ones that assist in both the absorption and direction of calcium. For example, AlgaeCal Plus includes vitamin K2, which helps direct calcium where it needs to go – into your bones – and away from soft tissues like the heart!

    Weight-bearing exercises are definitely beneficial to your bones! Feel free to check out the exercise section of our blog to get started today.

    For breakfast in the mornings, I usually have Almond milk and Organic yogurt in my fruit smoothies or with whole grain oatmeal. Both of course, have Calcium Ingredients. I’m also taking Algae Cal Plus daily as directed.
    I try to eat vegetables with calcium in my diet as well.
    My calcium levels from the fasting labs Show a normal 10.1 mg/dL. I will give credit to Algae Cal.

    Am I consuming too much calcium in my breakfast diet along with the Algae Cal?
    What do you recommend?

    February 3, 2020 , 3:22 pm

    Hi Robbie, thanks for sharing!

    Sounds like you’re eating a very healthy diet – keep up the great work! ?

    To clarify, are you consuming AlgaeCal Plus along with your breakfast? If so, you’re likely taking too much calcium at once. Our bodies can only absorb around 500mg of calcium in one go, so it isn’t helpful to take more than 500mg. If this is the case, would it be possible to take AlgaeCal 2 hours before/after breakfast?

    does this mean deficiency of calcium.

    Hi Utkarsh, thanks for reaching out!

    We checked in with Dr. Emma Gasinski, Physical Therapist. She advises that if this is your only symptom, this alone would not mean that you are having a calcium deficiency. It is a good sign that you are not experiencing pain and it is quite normal to hear cracking in the knees or ankles from just air within the joint that is getting released when you perform the sit up! If you do have any other symptoms or if this cracking starts to cause pain, it is advised to get this check out by your local MD.

    Hi,

    First of all thank you for the information doc.

    Does (severe) calcium deficiency also cause hair loss? Since its known that a vitamin D deficiency causes hair loss or even alopecia, now lets say you have optimal vitamin D status but you are still calcium deficient(maybe from a lack in diet), will you still lose hair? As in, does vitamin D’s role in calcium homeostasis directly and significantly affect hairloss, or is it other factors like hormonal influence etc from vitamin D that affects it apart from the calcium?

    Thank you☺️

    Thanks for reaching out, Margaret!

    Traditional calcium supplements often come as 1000 to 1200 mg of calcium on their own (or calcium with vitamin D). This can lead to excessive levels of calcium supplementation – without the right balance of other bone-supporting nutrients. AlgaeCal provides 720 mg of calcium that is much more effectively absorbed and used. See, AlgaeCal contains a naturally occurring trace mineral complex similar to the composition of our bones. It also provides additional vitamins and minerals which help in the absorption and direction of calcium. For example, vitamin K2 helps direct calcium into your bones and away from soft tissues like the heart! We also take into consideration that people will be getting about 500 mg of calcium from their diet – this means that you’re reaching the recommended amount of calcium all through natural sources! Please feel free to reach out to us over the phone at 1-800-820-0184 (USA & Canada toll-free) 5am-4pm PST on weekdays and 6am-4pm PST on weekends. We would love to hear from you! ❤️

    I have taken a bone medication for seven years due to Osteopenia and recently stopped as my DEXA scans numbers are getting worse and I fell and broke my hip. Will this product help to build bone if you have been on Ibandronate Sodium or is the damage done? They are wanting me to start another bone medication and that scares me. Thanks for any insight or information.

    Hi, I’m nearly 40. I breastfed my elder child for over 3.5 years and am currently nursing my 2.5 month old. While I don’t have any of the described symptoms yet, I want to preempt bone density loss. Is this product for me ? If yes, which of the products? Also how long should I be consuming it? Can I have it while breastfeeding ? Thank you.

    Hi Nandini!

    Thanks for reaching out with your question! If you’re looking to maintain strong, healthy bones, we recommend AlgaeCal Plus. However, if you are breastfeeding we recommend consulting with your physician to see if AlgaeCal Plus is right for you at this time. We have an excellent information sheet you can share with your doctor here. Hope this helps!

    Hi, my 25 yr old son was diagnosed with osteoporosis, (-4.1 lumbar z score and -2,6/-2,.7 femoral neck). He is strictly tube fed, so altering his diet is out of the question, his daily intake of formula includes 2800 mg calcium (Calcium Phosphate, Calcium Pantothenate) plus a wide variety of other nutrients. We also add 6,000 iu of D3. Would love to see if there is anything else nutritionally we can supplement, but not sure he really needs anymore calcium at this point, as his labwork shows he is getting sufficient amounts and we cant exactly replace what is in his formula (called compleat pediatric, uses some real foods as part of the formulation). Is there any benefit that you can share for me to discuss with his team regarding adding this product to his regimen? Thanks!

  102. Kirby Johnson

    December 17, 2021 , 2:47 pm

    Heidi,

    We’re so sorry to hear of your son’s diagnosis – thank you for providing us information on his circumstances. Aside from calcium, our formulation provides 13 minerals and 3 vitamins needed for healthy bones. This includes nutrients that help with proper calcium absorption and assists in placing calcium directly into your bones. This complete formulation is clinically supported in 3 human clinical studies to increase bone mineral density and we’ve helped thousands of people do so. While your son may not be able to take our supplements directly, we’d advise discussing certain components of our formulation with your doctors to determine if they would be appropriate to add to your son’s intake. You can read more about these ingredients HERE. Wishing you all our best – please don’t hesitate to let us know if you have further questions!

    I was skeptical about taking this product but knew I needed to get away from rock-based calcium, as my body was not absorbing it. I start 3 weeks after my bone density (2020). I have osteopenia, but because of my numbers, the location, and the difference between the numbers in different areas (if I am understanding what they are telling me) the dx is osteoporosis. I started algaecal and strontium, PLUS bone med infusions and walking 30 min x 5 days/week.
    I just got the results from my 2022 dexa – scan – 38% improvement!!!! YAY! I am reordering as we speak. :))

    I agree with almost everything you said and it’s nice that someone finally said it. The one issue I have is that vitamin k1 converts to k2. The problem with taking k2 is that k1 won’t need to convert so wouldn’t supplementation of vitamin k2 cause k1 to build up inside the body?

  110. Chelsea Dugas

    September 14, 2022 , 8:05 am

    Hi, Nancy!

  112. Chelsea Dugas

    September 14, 2022 , 1:51 pm

    Hi, Mary,

    Calcium bumps are definitely an unwanted side effect. Unfortunately, the majority of calcium supplements provide an excessive dose of calcium on their own (or calcium with vitamin D), without the many other nutrients needed for proper absorption into bone. AlgaeCal is a whole food source of calcium with a wide variety of naturally occurring trace minerals, plus added vitamins D3, K2, and C, and boron! This perfect balance of vitamins and minerals all work together to keep calcium out of soft tissue and deliver it straight to where it’s needed – our bones! The safety of AlgaeCal is confirmed in all three of our human clinical studies. To review the research, visit our website HERE.
    For further information and personalized support, feel free to contact our friendly Bone Health Consultants, 7 days a week, at 1-800-820-0184 (USA & Canada, toll-free) or email [email protected]. Hope this information helps! 🙂

    Hi Jane,

    AlgaeCal actually naturally contains a number of different forms of calcium, including calcium hydroxide, sulphate, chloride, phosphate, and carbonate, along with a very broad spectrum of trace minerals. We’ve also added essential bone-health nutrients such as vitamin D3, K2 and boron, which helps direct your calcium into your bones! This makes our formula a bone-health supplement, instead of just calcium!

    We’re also proud to say that AlgaeCal is the only calcium supplement shown to increase bone density in clinical research so far. To review the studies, visit our link HERE 🙂

  126. Kendra AlgaeCal

    September 26, 2022 , 2:36 pm

    Hi Irene,

    Great question! We would recommend you to take both our AlgaeCal Plus and Strontium Boost! This will ensure that you have the maximum support to improve your bone density 🙂 Once you’re at a healthy range in all areas measured on your DEXA scan, the Strontium Boost will no longer be necessary at that point! The AlgaeCal Plus on its own will be able to maintain your healthy bone density.

    We hope this helps!

    The nutrients provided by AlgaeCal will be primarily absorbed in the small intestine; however, some nutrients, such as the calcium and magnesium AlgaeCal provides will also continue to be absorbed along the length of the large intestine. Hope this answers your question! 🙂

    Hi Elizabeth!

    Great question! It is not common to experience constipation with AlgaeCal. Traditional calcium supplements often cause constipation because they supply only calcium or calcium and vitamin D. It takes a variety of nutrients for proper absorption of calcium, and AlgaeCal Plus provides all of these…in the right amounts! For more information on this topic, please visit our website HERE!

    Why do you think a person who is lactose intolerant and virtually never eats cheese or dairy would have a high normal calcium level and a very good decaf score? It just seems counterintuitive and I feel like crap. I often think it is a lack of bio available calcium or something. I do believe there is a connection.

  134. Brianne Bovenizer

    October 24, 2022 , 8:02 am

    Hi Paulee,

    Thank so much for reaching out, and I am so sorry to hear that you are not feeling well. There are many factors that can contribute to a higher than normal calcium level. I would suggest working more with your health care practitioner, and asking them to test your parathyroid, if they have not already. You could also try reaching out to a Functional Medicine Practitioner, who may be able to help investigate what is driving this, and you can find one in your area by clicking HERE!

    How many milligrams of calcium and magnesium should a 75 year young woman take daily. I take 2 pills (150 mg) each daily and 1 pill 650 mg of calcium a day. Am I taking the right amount?

  136. Brianne Bovenizer

    October 25, 2022 , 10:34 am

    Hi Marlene,

    This is a great question! We know from our clinical research, that the 720 mg of calcium (in AlgaeCal Plus), with your dietary calcium, which for most people is around 500mg per day, is the right amount to support your bones! Calcium and magnesium are best taken at a 2:1 ratio. That said, it is also important to remember that the bones need much more than just calcium and magnesium in order to be properly, and fully supported. So even though you may be taking the right amount of calcium and magnesium, you may still be missing out on some other, very important nutrients, like vitamin D3 and K2, just to name 2. For more information on this, click HERE.

    With all this said, we are proud to offer the only calcium supplement that is clinically supported to increase bone density! AlgaeCal Plus conveniently contains all 16 essential nutrients to support your bones, and for more information of this, click HERE!

    Hi Tina,

    So great to hear you are taking dairy, D3 and magnesium. Keep in mind that your bones need a total of 16 nutrients to be fully supported, which include all of these as well as vitamin K2, as you mentioned, boron and trace minerals. It’s so unfortunate that K2 is often forgotten, and it is so important to ensure calcium gets to where it needs to go – the bones! The good news is that AlgaeCal Plus contains all 16 essential bone supporting nutrients, all in one supplement! It is also the only calcium supplement clinically supported to increase bone density! 🙂

    Hi Jo-Ann,

    Thank you for reaching out! I’m sorry to hear that you’re living with bone loss and arthritis, and can certainly understand that you’re looking for a natural way to increase your bone density – AlgaeCal can do exactly that! As a plant-based calcium, it provides your body with all the essential bone building minerals, in the correct proportions to ensure optimal absorption and placement to the bone. 🙂

    With that in mind, our human clinical studies have shown that when taking AlgaeCal Plus and Strontium Boost, on average you’re able to see a 3% increase in bone density each year. Furthermore, our supplements are also clinically supported to be side-effect free! You can read more about our clinical studies HERE.

    Additionally, if you are currently taking prescription medications or plan on adding the above medications to your regimen, we would suggest checking in with your doctor or pharmacist for potential separation guidelines from our supplements!

    We would love to answer any other questions you have and get started on our program, so please feel free to reach out to our Bone Health Consultants at 1-800-820-0184 (USA & Canada toll-free) – we’re always happy to help!

    Great question, Marlene! If you’re experiencing accelerated bone loss, our Bone Builder Pack is the best option for increasing bone density. While AlgaeCal alone showed average bone density increases of 1.3% per year in our clinical studies, adding Strontium Boost tripled this rate! Also, while AlgaeCal has been studied specifically for improving bone mineral density and not arthritis, you may benefit from our product called Triple Power Fish Oil! It eases oxidative stress through a combination of EPA + DHA omega 3s, turmeric, and astaxanthin. We also have an article on natural remedies for arthritis you may find helpful here!

    You’re welcome to place an order on our website here. For the most personalized recommendations, we encourage you to give our Bone Health Consultants a call at 1-800-820-0184 (USA & Canada toll-free). They are super knowledgeable and always happy to help! 🙂

  157. Brianne AlgaeCal

    June 20, 2023 , 12:22 pm

    Great question, Gean! 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 is FDA registered and has Health Canada approvals. It has been on the market for 20 years and has 3 clinical studies and a toxicology study showing extraordinary safety. You can see more about our studies HERE!

    Great question Sara! Yes, our calcium supplement includes added magnesium and boron for a synergistic effect. Magnesium enhances calcium absorption and plays a crucial role in bone health. Boron, on the other hand, supports the utilization of both calcium and magnesium. Together, these minerals contribute to overall bone strength and health. If you have any more questions or would like further details, feel free to ask. We’re here to provide the best support for your well-being!

    Thank you for your question, Sally. It is not common to experience constipation with AlgaeCal. Most calcium supplements cause constipation because they supply only calcium or calcium and vitamin D. It takes a variety of nutrients for proper absorption of calcium, and AlgaeCal Plus provides all of these…in the right amounts! For more information on this topic, visit our website HERE. For further peace of mind, we provide full refund on any unopened and even partially used bottles within a year of your purchase date under our Risk Free Returns Policy, so this gives you a full year to safely test-drive our products!

    We are sorry to hear that your most recent DEXA scan showed a decline in your bone density, Sally. We recommend AlgaeCal as part of any bone health regimen. AlgaeCal is the only calcium supplement clinically supported to increase bone density (studies HERE), and it provides the vitamins and minerals that are needed for healthy bones! Beyond the studies, we have many customer success stories with before and after DEXA scans that you can take a look at HERE. If you would like to review this with your doctor, we suggest bringing THIS information sheet to your next appointment.
