Ortho Molecular Vitamin D 5000 IU - 120 ct
Vitamin D is most widely known as the sunshine vitamin because our bodies are able to make vitamin D when exposed to sunlight for a period of time. It has received a lot of press in recent days and is probably most well known for the role it plays in supporting bone health. Vitamin D also plays an important role maintaining cardiovascular function, immune function, and promoting an overall sense of well-being.
Vitamin D is converted in the body to the active 1,25(OH)2 form. This conversion is regulated by parathyroid hormone (PTH) and low levels of calcium and phosphorus. Vitamin D is available in two different forms, D2 and D3. Vitamin D3 is the preferable form as it has been found to modulate 25(OH)D levels for a longer period of time when compared to vitamin D2.
