OD. Calcium is important to overall health.
Vitamin D's best known trait is probably the role it plays
in maintaining healthy bones. Vitamin D sends chemical
messages to your intestines to increase the absorption of
calcium, an important nutrient in creating healthy bones. It
not only helps to form and maintain bones by promoting
calcium absorption, it also works with other vitamins,
minerals, and hormones to promote bone mineralization,
Without Vitamin D, bones can become thin, brittle, and
deformed. Having enough Vitamin D in your diet prevents
skeletal diseases that weaken bones. Vitamin D also helps
prevent the onset of osteoporosis, a disease that weakens
bones. Vitamin D helps stop osteoporosis if it has already
started.
