Your body makes vitamin D when your skin is exposed to the ultraviolet B (UVB) rays in sunlight. About 5 to 30 minutes of exposure to the skin on your face, arms, back or legs (without sunscreen) two times every week is enough.

The Reference Daily Intake (RDI) is 400 IU of vitamin D per day from foods, but many health organizations recommend getting 600 IU (3).
