Strontium is a trace mineral which concentrates in the skeletal system where it supports the function of osteoblasts (the cells which form new bone) while reducing the differentiation and activity of osteoclasts (the cells which resorb old bone). Strontium Support II helps support bone mineral density. Supports Bone Mineral Density - Stimulates bone growth while slowing bone loss - Reduces the risk of fractures - Clinically effective dose & safe for long-term use Amount: 1 Capsule Strontium (citrate) Non-medicinal ingredients: Capsule: hypromellose. Suggested Use: (Adults 50 years and older): Take 1 or 2 capsules daily on an empty stomach at least two hours before or after consuming food calcium or milk since these can significantly reduce strontium absorption if taken together. Ensure an adequate daily intake of calcium and vitamin D. Cautions : May cause temporary transient increases in levels of creatine kinase that are unassociated with any disorder.
