Why take a vitamin D supplement?
Once thought to only be important for bone health, scientists have now found that vitamin D has important actions in almost every cell in the human body, and controls the expression of over 200 different genes. Sufficient vitamin D is crucial to the proper function of many of our body’s tissues.
It is difficult (and potentially harmful) to get enough vitamin D from the sun. For most people, the main source of vitamin D is exposure to sunlight, which prompts vitamin D production by the skin. Very few foods naturally contain vitamin D, and achieving adequate vitamin D levels via sun exposure is difficult, considering that most of us have indoor jobs, and cover much of our skin with clothing, especially during winter.
