Vitamin D3 promotes healthy immune function, strong bones and teeth.
The body can manufacture vitamin D when skin is exposed to ultraviolet light.
Season, time of day, length of day, cloud cover, smog and skin melanin content are among the factors that affect UV radiation exposure and vitamin D synthesis. Few food sources provide sufficient vitamin D, so sunlight exposure or supplementation is important. However, low exposure to the sun or exposure exclusively with thick, total sunscreens means that this source of vitamin D can be very low and supplementation is required to provide sufficient vitamin D for all the body's requirements.
Vitamin D is a fat-soluble vitamin essential for normal growth and development. It is required for the absorption and metabolism of calcium and phosphorus to support the necessary hardening of bones. Its role in the absorption of calcium is also key for a healthy neuromuscular system, muscle strength, normal blood clotting and heart function.
Vitamins A and D taken together have been shown to reduce the incidence of colds, reduce muscle spasms (especially when related to anxiety states) and ease asthma and arthritis.
Studies have shown that omega fatty acids and Vitamin D are associated with longer, healthier telomeres. With each cell cycle, telomeres, the protective caps at the end of chromosomes, shorten when telomeres become too short, the cell dies.
Vitamin D has other roles in the body, including modulation of cell growth, neuromuscular function, immunity and the reduction of inflammation. Vitamin D modulates many genes which encode proteins that regulate cell proliferation, differentiation and apoptosis. Many cells have vitamin D receptors.
A growing body of research suggests that vitamin D might play some role in the prevention and treatment of type 1 and type 2 diabetes, hypertension, glucose intolerance, multiple sclerosis, osteoporosis, cancer and other medical conditions. A number of studies as well as epidemiologic data suggest that vitamin D status could affect cancer risk.Buy Lumity
