Vitamin D

Vitamin D is a fat-soluble vitamin that promotes strong and healthy bones. As your body is exposed to natural sunlight, vitamin D is created internally. Low levels of vitamin D can lead to increased risk or susceptibility to infection. Vitamin D has also been shown to combat depression, and to maintain heart and lung health.
