Strontium is a trace mineral naturally present in small amounts in the human body, where it tends to concentrate in bones and teeth due to its chemical similarity to calcium. Research suggests that strontium may support bone health by influencing the balance between bone formation and bone resorption, and strontium ranelate has been studied extensively in clinical trials for its potential role in maintaining bone mineral density, particularly in postmenopausal populations. Strontium citrate is available as a dietary supplement in many countries, while strontium ranelate remains a prescription option in certain regions. Studies indicate promising associations between strontium supplementation and markers of bone strength, though researchers continue to explore its long-term effects and optimal use, and individual responses may vary based on overall health and nutritional status.
