Thank you for this thorough post. My endocrinologist went as far as to say that she would no longer treat me if I were to use AlgaeCal, citing an FTC lawsuit (which mainly pertained to the marketing claims). You can do a simple search for case No. 12-12382-AA against "Garden of Life"

I am, however, interested in trying strontium citrate. I see the amount in AgaeCal is 680 mg. I am curious as to the dose you are currently taking, as this seems high?
