Vitamin D

About 20% of calcium is contained in the bones, which gives them the necessary strength, the rest of the calcium is contained in tissues and body fluids. If the body does not have enough calcium in the diet, it drains it from the bones. They then lose strength and break easily. Bone thinning (osteoporosis) occurs.

Vitamin D contributes to the normal absorption and utilization of calcium and phosphorus, to the maintenance of normal bones and teeth, to the activity of muscles and to the normal function of the immune system.
