Aside from helping power the immune system—which begins to degrade as we get older—Vitamin D helps the body absorb calcium, which can build bone density. As the body ages, it needs assistance there: The bone-weakening condition known as osteoporosis affects approximately 44 million Americans—nearly half of everyone over age 50. Vitamin D is also important to muscle metabolism, which declines with age. Good food sources of vitamin D include fatty fish like salmon, eggs and fortified milk and cereals. But it may be difficult to get sufficient amounts of the vitamin from food, so supplementation may be a good idea.
