Vitamin D

Vitamin D helps your body absorb calcium, and the two nutrients work together to help you maintain healthy bones and teeth. Vitamin D also helps your muscles, nerves, and immune system work properly. It helps white blood cells recognize foreign invaders and may also influence the release of protective proteins when needed.

Moreover, vitamin D protects neurons to promote healthy cognitive function. This nutrient is in a class of its own, with receptors everywhere in the body – including the muscles and heart – a hint that it plays a role in many more physical functions than we know.
