Take a vitamin D supplement
Unless you’re in a sunny climate all winter long, chances are, you’re not going to be soaking up the sunshine this winter. Vitamin D is needed for a lot of things, including bone health, and possibly protecting against high blood pressure, cancer, and other diseases. The Recommended Dietary Allowance for adults is 600 for most adults through age 70 and 800 IU for folks over age 70, although some health experts believe people need much more. If you decide to take a supplement, look for the “D3” form of vitamin D rather than the “D2” form, as the D3 form does a better job at increasing blood levels of this vitamin.
