"Vitamin D is a fat-soluble vitamin that is stored in the liver and fatty tissues of the body. Perhaps best known for its role in maintaining calcium balance and bone health, vitamin D is critical in many physiological processes, such as blood pressure regulation, immune function, and cell growth. Poor vitamin D status is implicated in the pathogenesis of many acute and chronic diseases, including rickets, osteoporosis, multiple sclerosis, and cancer."- Dr. Rhonda Patrick Click To Tweet
