Reviews

Great results from Dexa Scan

"My latest results from my Dexa Scan were really great. All three places scanned had significant increases in density. Very pleased."

Debbie W. (5/5)

Just do it! It works!

"I started using AlgaeCal bone builder pack a little over four years ago. Since then I've had two DEXA scans, both showing improvement in bmd. This last one a few months ago my doctor exclaimed that this just isn't seen in women my age and declared he is going to recommend AlgaeCal to his other patients. What else can I say? It really works!"

Chris R. (5/5)

My latest bone density scan

"My latest bone density scan came back showing I have osteopenia, and my doctor told me about the bone builder pack. She has other patients who are taking with good results. I have been on it for a few months. I am feeling good while on it. I will be taking my next bone density in November so I am hoping for improvement in my bone density."

Margeo H. (5/5)

After taking the bone builder

"After taking the bone builder pack for a year I went for my bone density test and it has improved significantly. My doctor told me I no longer had osteoporosis, it was osteopenia now. She told me to continue taking what I was taking. So yes there has definitely been an improvement and I am so glad I heard about this product because I was definitely against taking the shots my doctor had spoke to me about."

Gretchen M. (5/5)

A good product!

"I started taking the Bone Builder pack at my naturopath’s recommendation for osteoporosis about a year and a half ago. I was hoping to at least hold steady but was very pleased when my bone density scan showed a decent improvement a year later."

Susan B. (5/5)

Great improvement

"Just got my latest Dexa score back. Have improved from osteoporosis in my AP spine to osteopenia- a 13% improvement! MY hips have improved 9. 2%, but I have lost 1. 8% in my femoral neck and left forearm, which is weird. I am ramping up more heavy weight exercise for my forearms, but don’t know how to improve the femoral neck scores. Overall, very happy with the improvement."

Pam (5/5)

The product really works

"Very pleased with the results so far. After just 9 months, my scores improved significantly. Had a Dexa scan in March 2025, then another in Dec. 2025. Lumbar Spine Level went from T-Score -2. 6 to 1. 8 Fermoral Neck: T-Score -3. 8 to -3. 6 Left Hip (where I have osteoporosis) T-Score -3. 3 to -3. 0 Looking forward to seeing more improvement in 2 years."

Coren W. (5/5)

Grateful

"I started using the Bone Builder Pack just over 2 years ago (2024) when my bone density went from osteopenia to osteoporosis. My PCP had referred me to a physician assistant specializing in orthopaedics and bone density concerns. The PA recommended medication but I told her I wanted to try AlgaeCal. I had a dexa scan after both one and two years on the product with "statistically significant improvement" documented both times. When I saw the PA specialist after my 2025 dexa scan results she still referred to my condition as osteoporosis although my T scores had improved to the osteopenia range. She also told me not to expect my gains to last. I am grateful for continued improvement at statistically significant levels in 2026! That PA was sent my results again this year but I don't plan to check in with her again. My PCP is supportive of my path and pleased with my results."

Sarah R. (5/5)

2 years ago i was

"2 years ago i was diagnosed with Osteopenia. I started taking the bone builder pack and my last Dexa scan came back as normal. I no longer have osteopenia. I am absolutely thrilled! I take these supplements religiously. Without Algae Cal, i would probably have osteoporosis now!"

Carri W. (5/5)

I'm so glad I found this!!!

"I'm 54, when I was diagnosed for the first time, my dexa was L1-L4 of -4! This was 2 years ago. The pcp, endocrinologist, reumatologist, gyn, all talked me into the meds. . . i told them "give me a year to do this, and exercise, change diet, and if it doesn't work, I'll succumb to the meds" Now, me personally I don't "feel" anything different, but the dexas show the result, my worst number now is -3. 4! Everybody is different i know, and others might have underlying causes, but let me tell you, definitely it's working!! I use the builder pack, the D3, and the collagen. I'm glad it works for me!! You have to give it a try!"

Q&A

I use AlgaeCal Plus and am having positive results. My friend is on blood thinner and should not have the Vitamin K. She recently had a serious bone break so she's trying to figure out how to increase her bone strength. What do you recommend for her?
Thanks for your question, Vivian, and we're sorry to hear about your friend's bone health. It really depends on the specific blood thinner she is taking, as some may not interfere with AlgaeCal, while others do. As for discussing the right fit for her, we would love to chat with her to ask her a few questions and offer our personalized support! She is welcome to give us a call at 1-800-820-0184 (USA & Canada toll-free) and our friendly and knowledgeable Bone Health Consultants would be happy to help. :) - Coral
Why is the Strontium boost taken at night?
Great question, Kate! Strontium Boost can be taken at any time of day — the key is to take it at least 2 hours apart from calcium or calcium-rich foods, since calcium and strontium compete for absorption. Many people find that taking Strontium Boost before bedtime works well, as it’s typically when the stomach is empty. Plus, bone turnover is most active at night, making it a great time for your body to put it to good use. :) I hope this helps! Please feel free to give us a call at 1-800-820-0184 (USA & Canada, toll-free) or email support@algaecal.com with any follow-up questions! - Yoori
Hello - I'm interested in the Bone Builder pack. However, I have a food allergy - do any of the ingredients include either sunflower seeds or sunflower oils or a sunflower derivative - e.g., tocopherols, vitamin E, etc. I'm also allergic to coconut oil. Please advise. Thank you.
Thank you for reaching out, Laurie! Both the AlgaeCal Plus and Strontium Boost does not have any coconut oil, sunflower seeds, sunflower oils, or a sunflower derivative included. That said, for any severe allergies we do advise consulting with your doctor/allergist for their best recommendation. Here is our Doctor Information Sheet for your convenience: https://blog.algaecal.com/wp-content/uploads/Doctor-Info-Sheet-BBP.pdf. I hope this helps! - Yoori
I am newly diagnosed with Alpha Gal. The ingredients look vegan but just making sure there are no ingredients that are sourced from mammals. Thanks.
Thank you for reaching out, Paula. Please note that AlgaeCal Plus is not considered vegan, as it includes vitamin D3, which is derived from lanolin (sheep wool). We recommend consulting with your healthcare provider before trying any new supplement to ensure it aligns with your specific needs.

My sister turned me on to this product and submitted my email address and hers, but i am thinkinfg she may have given the incorrect Email address for me, as I have not yet heard from you! Her name is Jessie Morgan and I wanted to make sure she got credit for this, me too!
Thank you for reaching out, Lynn! I'm so glad to hear that your sister, Jessie, recommended AlgaeCal to you. :) I can confirm that Jessie received her 400 reward points for referring you! And I'm happy to share that you received a 10% discount on your first order, which amounted to a savings of $91.20. That’s actually a greater value than the standard $20 referral discount. Just a friendly note: referral discounts can’t be combined with the 10% discount we have offered you. :) I hope this helps, Lynn!
