Vitamin D is required by our bodies to regulate a number of important functions, much like a hormone. Vitamin D supplements usually contain Vitamin D3 (Cholecalciferol). While all mammals can synthesize adequate Vitamin D from sufficient sunlight, taking a D3 supplement may help to prevent Vitamin D deficiency and associated symptoms, especially in Winter or for those working indoors.
Most of us are aware that we produce vitamin D through exposure to sunlight. Varying factors such as the latitude you live at, the time of day you spend in sunlight, changing seasons, your age, culture and your type of skin pigmentation all have a major influence on how much vitamin D you produce through the skin. Studies show at least 40% of us have insufficient levels of this important vitamin, while 3- 4% are clinically deficient.
Vitamin D is one of the fat soluble vitamins and in its bioactive form (1,25 D) is required by our bodies to regulate a number of important functions, much like a hormone. It is an essential factor in calcium absorption, maintaining normal blood levels of calcium and phosphorus, bone formation and strength, muscle integrity and immune function. It has a significant role in reducing inflammation. Most importantly, 1,25 D controls the development of many serious diseases by its proven role in inhibiting the conversion of healthy tissue to diseased tissue.
