Vitamin D 1000 IU

by Ortho Molecular Products


Vitamin D is a steroid hormone that has long been known for its important role in regulating body levels of calcium and phosphorus, and in mineralization of bone. More recently, it has become clear that receptors for vitamin D are present in a wide variety of cells, and that this hormone has biologic effects which extend far beyond control of mineral metabolism. It is implicated in regulation of immunity, mood, and metabolism
