Description
Vitamin D refers to a group of fat-soluble secosteroids responsible for increasing intestinal absorption of calcium, iron, magnesium, phosphate and zinc. Vitamin D is produced by skin exposed to ultraviolet B radiation or obtained from dietary sources, including supplements. Average daily vitamin D intake in the population and current dietary reference intake values are often inadequate to maintain optimal vitamin D levels. Virtually every cell in our body has receptors for Vitamin D, meaning that they all require “sufficient” level of Vitamin D for adequate functioning.
Vitamin deficiency has been linked to various serious diseases: osteoporosis, multiple sclerosis, cardiovascular diseases, pregnancy complications, diabetes, strokes, autoimmune diseases, infectious diseases, etc.
