Vitamin D May Protect Against Viral Infections During the Winter

(Science Daily)  Vitamin D may be known as the sunshine vitamin, but a new research report… 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. Since vitamin D levels decrease during autumn and winter when days are shorter and sunlight is relatively weak, this may explain why people are more prone to viral infection during these times.
It also suggests that increased vitamin D intake, especially in older populations, could strengthen people's innate immunity against viral infections.
