Orthoplex Rapid D has been formulated using Calcifediol, a more potent, soluble and bioavailable form of vitamin D. With a higher rate of intestinal uptake, Calcifediol is absorbed into the portal vein circulation and by-passes liver metabolism, increasing vitamin D levels up to three times more efficiently than standard vitamin D (colecalciferol). Using the main form of circulating vitamin D in the body, Rapid D is a one-a-day formula that increases Vitamin D levels and supports the immune system to fight illness.
