I take the amount which research studies has said works for osteoporosis. 680mg daily of strontium.
I take strontium last thing at night away from all calcium products. I take calcium all day long and check on cronometer to see if I need to supplement calcium in case my diet is lacking.

Calcium and strontium use some of the same receptors in the body and the body will ignore strontium in favor or calcium. This is the reason for taking them at different time periods.
