Vitamin D May Protect Against Viral Infections During The Winter

itamin D may be known as the sunshine vitamin, but a new research report appearing in the Journal of Leukocyte Biology shows that it is more than that. According to the report, insufficient levels of vitamin D are related to a deficiency in our innate immune defenses that protect us from infections, neoplasias or autoimmune diseases.

Skin ‘Sees’ UV Light, Starts Producing Pigment

In a new study, biologists report that melanocyte skin cells detect ultraviolet light using a photosensitive receptor previously thought to exist only in the eye. This eye-like ability of skin to sense light triggers the production of melanin within hours, more quickly than previously thought, in an apparent rush to protect against damage to DNA.

Poor Control Of Diabetes May Be Linked To Low Vitamin D
