Vitamin D is necessary for building and maintaining healthy bones. That's because calcium, the primary component of bone, can only be absorbed by your body when vitamin D is present. Your body makes vitamin D when direct sunlight converts a chemical in your skin into an active form of the vitamin (calciferol).
Vitamin D isn't found in many foods, but you can get it from fortified milk, fortified cereal, and fatty fish such as salmon, mackerel and sardines.

The amount of vitamin D your skin makes depends on many factors, including the time of day, season, latitude and your skin pigmentation. Depending on where you live and your lifestyle, vitamin D production might decrease or be completely absent during the winter months. Sunscreen, while important, also can decrease vitamin D production.

Many older adults don't get regular exposure to sunlight and have trouble absorbing vitamin D, so taking a multivitamin with vitamin D will likely help improve bone health. The recommended daily amount of vitamin D is 400 international units (IU) for children up to age 12 months, 600 IU for ages 1 to 70 years, and 800 IU for people over 70 years.

Evidence
Research on vitamin D use for specific conditions shows:

Cancer. Research suggests that vitamin D, especially when taken with calcium, might help prevent certain cancers.
Cognitive health. Early research suggests that vitamin D might play a role in cognitive health. In one small study of adults age 60 years and older being treated for dementia, researchers found that taking a vitamin D supplement helped improve cognitive function.
Inherited disorders. Vitamin D supplements can be used to help treat inherited disorders resulting from an inability to absorb or process vitamin D, such as familial hypophosphatemia.
Multiple sclerosis. Research suggests that long-term vitamin D supplementation reduces the risk of multiple sclerosis.
Osteomalacia. Vitamin D supplements are used to treat adults with severe vitamin D deficiency, resulting in loss of bone mineral content, bone pain, muscle weakness and soft bones (osteomalacia).
Osteoporosis. Studies suggest that people who get enough vitamin D and calcium in their diets can slow bone mineral loss, help prevent osteoporosis and reduce bone fractures.
Psoriasis. Applying vitamin D or a topical preparation that contains a vitamin D compound called calcipotriene to the skin can treat plaque-type psoriasis in some people.
Rickets. This rare condition develops in children with vitamin D deficiency. Supplementing with vitamin D can prevent and treat the problem.
Generally safe
Without vitamin D your bones can become soft, thin and brittle. Insufficient vitamin D is also connected to osteoporosis and some types of cancer. If you don't get enough vitamin D through sunlight or dietary sources, you might need vitamin D supplements.

Safety and side effects
Taken in appropriate doses, vitamin D is generally considered safe.

However, taking too much vitamin D can be harmful. Children age 9 years and older, adults, and pregnant and breast-feeding women who take more than 4,000 IU a day of vitamin D might experience:

Nausea
Vomiting
Poor appetite
Constipation
Weakness
Weight loss
Confusion
Disorientation
Heart rhythm problems
Kidney damage
