Under normal circumstances, two parts of calcium coexist in the body with one part each of magnesium and phosphorus. Skeletal Strength formula contains extra amounts of magnesium so that calcium is encouraged to remain in the bones. Phosphorus , when kept in balance, works in partnership with calcium. Vitamin A also promotes the efficient use of calcium. It's needed for the growth and maintenance of healthy bones, especially in post-menopausal women.
Vitamin D is required for proper bone mineralization.
It also works to increase intestinal absorption of calcium and phosphate. Vitamin B6 is involved in protein metabolism needed for strong bones, and assists in the production and function of new red blood cells. It also has a role in shortening bone fracture healing time. Trace minerals iron and manganese are essential for calcium absorption. However, your diet should include more than a trace of potassium, which aids proper muscle function, strength and control.
