I agree with Denise about strontium citrate, because I am living proof also. I just got my Dexa report back with the added TBS report for bone quality , good normal bone density with normal TBS or bone quality.
I do not take algae cal, but I have taken strontium citrate for over 20 years. You may find strontium citrate at a good price point on many sites. Over 20 years of use with no side effects and no fractures.
