Mayo Clinic Minute - Do you need more vitamin D in the winter?

Vitamin D is a nutrient your body needs to keep your bones healthy and strong. It also has properties that support your immune system and neuromuscular health.

Dr. Jesse Bracamonte, a Mayo Clinic family medicine physician, says one of the main ways your body gets vitamin D is through direct sunlight on the skin. And during winter in the Northern Hemisphere, that can sometimes be a challenge.
