A mineral chemically similar to calcium, sold in supplement form usually as strontium citrate.

Why it’s used

Taken by some for bone health support, based on its structural similarity to calcium.

What the evidence is for

bone mineral density changes, studied primarily with strontium ranelate, a prescription form.

What the evidence says

The strongest human evidence for strontium and bone density comes from trials of strontium ranelate, a prescription compound studied and used in some countries for osteoporosis, not the citrate form typically sold as a dietary supplement. Direct evidence for strontium citrate at supplement doses is much thinner.

Context

Ranelate trials such as the TROPOS study used a fixed prescription dose distinct from over-the-counter strontium citrate products, so results from that research do not directly translate to supplement labels.
