Do Doctors Recommend AlgaeCal?

Updated: February 14, 2024

If you’re suffering from bone loss, here’s great news:

Doctors have discovered a natural calcium supplement that’s clinically shown to not just stop bone loss…

But actually increase bone density.

That’s right—a safe, natural, and clinically supported way to INCREASE bone density…

The company that makes this bone-building supplement is called AlgaeCal…

And the supplement is called “AlgaeCal Plus”.

So, why do doctors love AlgaeCal Plus?

1. The only calcium supplement that increases bone density

16 nutrients for stronger bones

How does AlgaeCal increase bone density? By giving your bones all 13 minerals and 3 vitamins they’ve been losing for years.

Most calcium supplements contain only calcium (and maybe vitamin D). Yet even with the recommended amounts of those two nutrients, studies show we still lose bone.

But AlgaeCal contains all the essential vitamins and minerals your bones need to rebuild themselves.

We know this is true because AlgaeCal is…

2. Backed by medical studies


Three separate clinical studies show AlgaeCal increases bone mineral density. The shortest study was 6 months, and the longest was 7 years.1 2 3

Most women with inadequate calcium intake lose about 1% of their bone density each year after age 40. But in the AlgaeCal studies, the women taking AlgaeCal actually increased bone density.

These studies show AlgaeCal strengthens bones in as little as 6 months, and continues to build new bone year after year for at least 7 years. DEXA bone scans of the studies’ participants show this is true.

The studies are found in prominent peer-reviewed journals: Nutrition Journal, International Journal of Medical Sciences, and the Journal of the American College of Nutrition.

This is why we’re confident enough to announce that AlgaeCal is…

3. Guaranteed to increase your bone density—or your money back

When you take AlgaeCal Plus and Strontium Boost together, we guarantee you will see increased bone density in EVERY follow-up bone scan you have while using these 2 products—or we will refund every penny you paid for our products between your scans. This guarantee extends to every scan you have for the next 7 years.

Plus, our One-Year Money Back Guarantee either leaves you 100% satisfied, or you get your money back. Period. That means during the first year, you can get a full refund at any time, for any reason.

The best part is, you don’t have to wait long to see results. That’s because AlgaeCal…

4. Starts working immediately

The first day you take AlgaeCal, your bones will start healing and getting stronger. And measurable results usually show up in just 6 months.

So when you go back to your doctor’s office for your follow-up DEXA scan, don’t be surprised when they tell you your numbers look great. (Many AlgaeCal customers feel a sense of pride when their doctor asks what they’ve been doing to get such amazing results. That’s when you get to educate your doctor!)

But is AlgaeCal safe? Studies say “yes”. That’s because AlgaeCal is made almost entirely of…

5. Plant-based ingredients


Traditional calcium supplements are made from limestone—a lifeless rock. But AlgaeCal is a kiwi-sized South American marine algae—a living plant. This rare algae is hand harvested, sun dried, then milled into a powder. There is no extraction process, and no additives. The only “ingredients” are pure, whole-food calcium and other bone-building minerals.

These pure ingredients are what makes AlgaeCal easy for our bodies to digest. And they’re also the reason AlgaeCal is… 

6. Vegetarian, kosher, non-gmo, gluten-free, soy-free and dairy-free

AlgaeCal’s ingredients are safe, pure, and sustainably harvested. Plus, AlgaeCal is kosher, non-gmo, gluten-free, soy-free and dairy-free.

And because it’s made of safe, all-natural ingredients, none of the women in the three studies experienced any adverse effects.

But were the results of the studies typical? Will AlgaeCal work for you? Through more than 18 years watching women of all ages and backgrounds take AlgaeCal with amazing results, we’re confident in saying “YES!”

In fact, AlgaeCal…

7. Works no matter your age


We’ve seen women in their 40s with severe bone loss increase their bone density with AlgaeCal… and we’ve seen women in their 80s do the same.

AlgaeCal works no matter your age, because everyone’s bones—whether a person is 45 or 85—still need the same vitamins and minerals to grow stronger.

That’s also the reason why AlgaeCal…

8. Works no matter the current condition of your bones


Slight bone loss or severe, it doesn’t matter. For example: an AlgaeCal customer named Debby D’Arcy discovered she had severe bone loss when she fell and broke her wrist. Shortly after the fall, she started taking AlgaeCal.

Since then, Debby has gotten several DEXA scans, and every one of them has shown her bone density increasing.

Not only that, Debby has had two more falls since then… but no more broken bones!

Another example is Sandy Ham. Her situation was even worse, with a starting T-score of -4.0. But in just 6 months on Algaecal, she improved to a -2.2, even with a long family history of bone loss!

Those are just two examples of why women love AlgaeCal so much. Plus, by strengthening your bones, AlgaeCal also…

9. Restores your active lifestyle

Maybe bone loss has made you slow down your physical activities, or even forced you to stop them altogether.

If you’ve had to compromise with any activities you love—like walking, gardening, or playing with your grandchildren… 

Or if you’re worried about losing your independence and having to rely on other people to take care of you… 

You’ll be overjoyed when AlgaeCal strengthens your bones and allows you to do all those activities again, with confidence.
In fact, that’s the real reason women love AlgaeCal. It gives them their active lives back.

    Is there a USP label attached to Algae cal products?

  5. Manja

    May 17, 2023 , 12:52 pm

    Hi A Bak! Thank you for your question. AlgaeCal does not have a USP label. AlgaeCal is USDA Certified Organic which means the harvest area is inspected regularly for possible pollutants. AlgaeCal is also made in an FDA inspected GMP (Good Manufacturing Practice) plant where the highest standards are maintained.
    Let us know if you need any more information.

    I have a shell fish allergy… is there any ingredients that contains fish oil?

  7. Samantha AlgaeCal

    Great question, Mary! There are no shellfish in AlgaeCal, only minerals from organic algae and added vitamins. Many of our customers have shellfish allergies and take our products without a problem! That said, for any severe allergies we do advise consulting with your doctor/allergist for their best recommendation. We have an excellent information sheet you can share with them here! As always, feel free to call our Bone Health Consultants at 1-800-820-0184 (USA & Canada toll-free) for more information. 🙂

    Who gives Algaecal kosher certification?

  9. Samantha AlgaeCal

    May 31, 2023 , 8:15 am

    Great question, Irene! Strontium Boost and our raw algae powder are certified kosher by Natural Food Certifiers (NFC). NFC holds the highest kosher standards and in addition, the natural certification means that there is no GMO technology in the raw materials manufacturing supply chain or packaging and no use of chemicals, dyes or other ingredients that are not naturally occurring. I hope this helps! Please feel to reach out to any one of our Bone Health Consultants at 1-800-820-0184 (USA & Canada toll-free) if you have any further questions. 🙂

    Do you have to take strontium with Algaecal to increase bone density

  11. Yoori AlgaeCal

    September 12, 2023 , 7:48 pm

    Great question, Marcia! AlgaeCal on its own is clinically supported to increase bone density by an average of 1.3% per year. However, we naturally lose around 1% of our bone density per year after the age of 40, and sometimes more depending on other factors like hormonal changes, genetics, lifestyle, etc. AlgaeCal alone is not always able to overcome this accelerated bone loss, so we always recommend Strontium Boost – because it tripled the rate of bone building in our studies!

    Yes I believe so. I have heard strontium will give a falsely higher density reading. The density score will show denser but strontium is not building stronger bones. I won’t take strontium. For ever after, your DEXA won’t be actually accurate. Notice Algae Cal has not responded to your question. They don’t want to admit it.

  13. Yoori AlgaeCal

    September 26, 2023 , 3:05 pm

    Thank you for sharing your comment, Barbara! Strontium does weigh more than calcium, and its mass does impact DEXA readings…but only by a very small amount. The possible overestimation is not great enough to discount DEXA results showing improvements in BMD. Furthermore, strontium has been shown to reduce fracture risk independent of bone density!

    There were concerns several years (~ 6 y) ago about AlgaeCal and its lead content. Has this been addressed? Was the formula updated since then.

    Thank you,

    Hi Valerie!
    We completely understand the concern caused by the AlgaeCal lead content quoted in the past. Unfortunately, in 2015 there was a human error made in the reported quantity and we are deeply sorry for the lack of clarity this has created. 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 the information about our studies HERE. Hope this information helps, Valerie! If you have any further questions, don’t hesitate to reach out.

    Is it enough to heal osteoporosis with the Algaecal supplement but without strontium. Another question is, if taking strontium, for how long max you should take it? I heard it affects deep sleep (it shortens it)

  20. Samantha AlgaeCal

    February 9, 2024 , 11:56 am

    Great question, Magdalena! AlgaeCal on its own is clinically supported to increase bone density by an average of 1.3% per year. However, we naturally lose around 1% of our bone density per year after the age of 40, and sometimes more depending on other factors like hormonal changes, genetics, lifestyle, etc. AlgaeCal alone is not always able to overcome this accelerated bone loss, which is why we recommend Strontium Boost – because it tripled the rate of bone building in our studies!
    That said, we recommend taking both AlgaeCal Plus and Strontium Boost until you’re back into a healthy bone density range (all T-score above -1.1). At this point, we suggest taking AlgaeCal Plus alone for bone density maintenance.
    For most people, taking Strontium Boost at bedtime is ideal as it can actually help with sleep. However, some people may feel like Strontium Boost is keeping them awake at night. In such cases, taking Strontium in the afternoon is perfectly fine. I hope this helps! 🙂
