I have been taking AlgaeCal since July 2018, occasionally Strontium and Triple Power 2X daily. I had three compression fractures in 2018. I tried Tymlos, (daily shots), but they knocked me out. Then my Endo Dr wanted me get the Prolia shot, and I said, No. He kept calling to convince me to take it. I now have a new Endo Dr, so far I like her, but only one apt. She wanted me to take fosamax, but I said, No. Told her I was sticking with the A/Cal; my next Dex Scan is next April, and hoping for bone growth and strengthening. I feel better, but also exercise a lot, and have changed my eating. Good Luck,
The AlgaeCal community has a fabulous onsite support group.

I am about to commence Algaecal and strontium. They claim amazing improvments in bone density and reference clinical research papers to back up their claims. I won't know effects until next bone density scan next year.

Have you looked up ingredents. Do . might tell you alot. I did and decided not to take it.

Hi; No bone scan until April, 2020, which is two years since the last scan. Feeling positive and hopeful tho.
Best of Luck with your decision.
