It's the dark days of winter in the Northern Hemisphere in which the sun shines less and is lower in the sky. That means your body has less of a chance of making vitamin D, the sunshine vitamin. Vitamin D is an essential nutrient, meaning your body can't produce it on its own. In this episode, we discuss what vitamin D is and what it does in your body, how you can get vitamin D and how using sunscreen affects how much you have, and what vitamin D defficiency means to your health.
