Vitamin D benefit

Vitamin D promotes absorption of calcium from the gut. Too much vitamin D may cause increased levels of calcium in the blood.

Calcium source

Getting enough calcium to keep bones from thinning throughout a person's life may be made more difficult if that person has lactose intolerance or another reason, such as a tendency toward kidney stones, for avoiding calcium-rich food sources. Calcium deficiency also effects the heart and circulatory system, as well as the secretion of essential hormones. There are many ways to supplement calcium, including a growing number of fortified foods.
