Dietary Supplement Non-GMO Strontium has been prescribed in Europe for years to promote healthy bone aging. Strontium is a trace mineral whose metabolism is closely linked to that of calcium. (It resembles calcium at the molecular level.) Strontium concentrates in the skeletal system, where it plays a key role in supporting bone tissue density. The suggested daily serving of 3 vegetarian Strontium Caps supplies 750 mg of this vital trace mineral. Strontium Caps are part of a daily nutrient regimen for individuals in need of especially comprehensive bone health support.
