Strontium

mineral

Strontium is an alkaline earth metal that shares chemical similarities with calcium, leading to its uptake by the body, particularly in bone tissue. While strontium ranelate is a prescription medication used to treat osteoporosis in some countries, strontium citrate is available as a dietary supplement. It is believed to work by stimulating osteoblast (bone-building cells) activity and inhibiting osteoclast (bone-resorbing cells) activity, thereby promoting bone formation and reducing bone breakdown. This dual action can contribute to maintaining bone mineral density.

Impact

Situational effect

Typical dose:340–680 mg

Strontium gets incorporated into bone tissue and appears to have a dual effect on bone turnover. While it has been shown to increase BMD measurements, it is a lower priority because its effect on actual fracture risk reduction is less clear compared to foundational nutrients.
