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.
