@joycecates Have you used the search bar on Mayo Clinic Connect? It's very useful. You can find the search bar at the top of this page. There is a magnifying glass icon and the word "Search".

I typed "red algae" in the Search bar and found many Discussions where our members have shared about their experiences and thoughts about the use of red algae for bone health. I did not list those discussions here as they are numerous and I thought you might like to pick and choose what to read.

Are you taking a calcium supplement currently and deciding whether you'd like to switch over to red algae?
