Longtime AlgaeCal customer

KarenDecember 1, 2025

I have taken AlgaeCal for over two years. The book "Healthy Bones Healthy You" (available at your library and/or Amazon) lays out the case for AlgaeCal much better than I can. I will say I closely followed the feedback on the Facebook page The AlgaeCal Community (for AlgaeCal users only) for almost a year before placing my initial order. That many ordinary people sharing improved DEXA scan results before and after at least one year on AlgaeCal eventually persuaded me that this product was worth the cost. I will have my first DEXA scan since beginning AlgaeCal soon and will come back and update. Here is information about the three studies done with AlgaeCal: "AlgaeCal has been studied in three human clinical trials conducted by researchers from leading institutions including Harvard Medical School, Georgetown University, and the University of Texas. The conclusion was the same across all three: AlgaeCal is the only calcium supplement ever shown to increase bone density‡" Read more

I HAVE CHANGED MY REVIEW TO 5 STARS cause of Customer Service

HunterJune 1, 2024

Like most of you, I paid extra money because this brand was involved in the calcium study. Then I went to the study and guess who sponsored the study? You guessed it - algaecal. If you read any studies then you know that the government makes the study mention if the study was sponsored. That is important because the company stands to make money on it as it can also be effective marketing. I don't have to tell you that $84 with tax was a huge waste of money for me. There are some pluses to like though. Easy to swallow pills, it's vegetarian. But I couldn't find a single study that says calcium from sea plants is better than calcium citrate. As both benefit your system. my only problem with this is that it's not worth eighty dollars. And that this company uses their own study to increase the price. Since other calcium companies that use kelp, algae are half this price. Here's what I did to get the best deal: SInce most supplements tend to not be what they say they are. All you have to do is watch journalist Johnny Harris on Y ou tube and he will tell you that supplements are not regulated by the us government. and that many supplements don't have any ingredients of what you buy at all. Any company can put any ingredients they want into a supplement since the FDA doesn't check. Although I don't believe this company has been dishonest in that regard. They are merely using their own study to up the price beyond what their supplement is worth. Here's how I bypassed supplements altogether. I went to my doctor and asked for a calcium citrate supplement. I went to my drug store and it cost about $4.00 for 1200 mg calcium daily for a 3 month supply with my rx card.. But here's the thing. It is 100% calcium citrate because the FDA does hold pharma companies accountable. And if this company is caught lying, no drug store or medical doctor will ever use it again. UPDATE --------------------- This company is so serious about their service, they actually emailed me and gave me my money back. I couldn't believe it. What I said before was true. However I would like to add that extracting calcium from the sea is a much more costly process. That's is why it's expensive. I still think it's expensive for me, but it it is high quality. Also, this company was very concerned about my satisfaction. They did not offer to give me my money back if I changed the review though. That is something that I did on my own. Read more

Worth the Money

Floyd A. ChildressDecember 13, 2025

I know I can't say *this is a miracle supplement* but it's so worth the money, and for me it has made such a significant difference in my bone strength. I had a knee replacement and my leg bone shattered so I ended up with screws and plates and years of PT...not ideal. I started taking Algecal Plus and my bones did fine with my next knee replacement. Plus my bone density tests show a big improvement in my hip bones which shocked my doctor. Yes Algaecal is pricey but to me it's worth every cent. Read more

Works For Me!

Laralea, BirminghamDecember 19, 2025

After an accident with literal bone crushing results, it was recommended that I take more calcium to strengthen my bones. Following surgery, on my first visit back to the orthopedist, I took with me a bottle of Red Algae Calcium for Bone Density to obtain an opinion from his perspective. After scanning the label and a little online research, he was impressed with my choice and encouraged me to continue. I can tell you now, it's physician approved and I am doing well. Read more
