Bests & Worsts Reviews from Amazon

This item made me sick to my stomach. Unfortunately I was just informed: Strontium has a long list of undesirable side-effects, commonly ranging from nausea to skin irritation, and less often (fortunately), blood clots and fainting. Since strontium is denser than calcium, it is difficult to assess actual bone improvement in a DEXA scan. Several studies conclude that strontium causes the outer cortical bone to become thicker, actually reducing tensile strength. This increases the risk of fractures. Strontium competes with calcium absorption. And to make matters worse this product is supposed to be guaranteed and I get message "no refund". Don't buy!
