Unlike other vitamins, vitamin D functions like a hormone, and every single cell in your body has a receptor for it.
Your body makes it from cholesterol when your skin is exposed to sunlight.
It's also found in certain foods such as fatty fish and fortified dairy products, though it's very difficult to get enough from diet alone.
Here are 6 common risk factors for vitamin D deficiency:
Having dark skin
Being overweight or obese
Not eating much fish or dairy
Living far from the equator where there is little sun year-round
Although sunlight exposure is one of the main ways to produce Vitamin D within the body, here are some Vitamin D rich foods to include in your diet, especially during the winter months when sunlight hours are reduced.
