Vitamin D enables your body to absorb calcium from food. Exposure to sunlight is the most natural way to help your body make vitamin D but it is important to balance your sun exposure. Overexposure to sunlight could make some women vulnerable to skin cancer. Also, depending on where you live and the time of year, sunlight may not always be available. For these reasons, the medical community no longer recommends relying only on sunlight as the primary source for getting vitamin D. It’s wiser to also consider food sources such as yogurt, orange juice, fish (mackerel, salmon), and fortified cereals.
