Vitamin Supplements

D31000 uses lanolin as a precursor, providing 1000IU per capsule. USP and European pharmacopeia compliant, this product is also Food Codex grade. Rigorous independent testing includes all supplier medicinal test results verified through independent 3rd party laboratories, thus ensuring the highest quality product. Ultraviolet B (UVB) rays from the sun penetrate the skin and converts 7 dehydrocholesterol to pre-vitamin D3, which in turn becomes vitamin D3 (cholecalciferol). Cholecalciferol is hydroxylated in the liver to form 25(OH)D3. 25(OH)D3 is then converted in the kidneys to the most active form of vitamin D, 1,25(OH)2D3. Vitamin D production is reduced when there is a decrease in the intensity of the sun’s rays. There are very few dietary sources of vitamin D, especially if consumed sparingly. Vitamin D is a factor in the maintenance of good health. It helps in the development and maintenance of bones and teeth; helps in the absorption and use of calcium and phosphorus; and helps to prevent vitamin D deficiency.
