4. Boosts Bone Health
Vitamin D is an essential nutrient that helps the body absorb calcium and phosphorus, which are critical for maintaining strong bones. Vitamin D also plays a role in immune function and cell growth.
A lack of vitamin D can lead to bone loss and other health problems. For example, children who do not get enough vitamin D may develop rickets, which causes softening and weakening of the bones. In adults, a vitamin D deficiency can lead to osteoporosis, a condition that causes bones to become thin and fragile.
