Summit Vitamins presents SEDDS Vitamin D3 w/ Ca as the perfect solution. Summit Vitamins SEDDS Vitamin D3 w/ Ca is produced through an all natural fermentation process and the unique Self Emulsified Drug Delivery System (SEDDS) technology. With the proprietary SEDDS technology, Summit Vitamins is able to transform Vitamin D3 into a water soluble molecule. This state-of-the-art manufacturing process combines the now water soluble vitamin D3 with water soluble, chelated calcium to produce a revolutionary, organic molecule SEDDS Vitamin D3 w/ Calcium. This cutting edge, natural dietary supplement can yield a five (5) fold increase the rate of absorption. Vitamin D3 is a fat-soluble vitamin that is naturally present in very few foods but is available as a dietary supplement. It is also produced endogenously when ultraviolet rays from sunlight strike the skin and trigger vitamin D3 synthesis. Calcium is required for muscle compression, blood vessel expansion and contraction, secretion of hormones and enzymes, and transmission of impulses throughout the nervous system. Vitamin D3 is essential for promoting calcium absorption in the gut and maintaining adequate serum calcium and phosphate concentrations to enable normal mineralization of bone. Sufficient vitamin D3 plus calcium is also required to prevent hypocalcemic tetany, a disorder associated with a deficiency in these nutrients. It is also needed for bone growth and bone remodeling. Other roles in human health include modulation of neuromuscular and immune function and reduction of inflammation. However, Vitamin D3 is fat soluble, not water soluble and thereby not easy to absorb. Similarly, calcium is a basic mineral which is also not significantly bioavailable unless it is bound to another material. Typically, calcium and carbonate are bonded to form calcium-carbonate, but the bioavailability remains poor because carbonate is also an inorganic substance. The challenge i
