Vitamin D is a fat-soluble vitamin that provides general cellular support, in part by supporting immune cell activity and by maintaining healthy cell metabolism. In a clinical trial, Vitamin D supplementation was shown to support Vitamin D-regulated genes associated with immune function, response to stress, and DNA repair. Vitamin D also supports healthy immune cell activation due to the presence of vitamin D receptors in immune cells, including lymphocytes and macrophages.‡
