Vitamin D, sometimes called the "sunshine vitamin," is an essential vitamin that plays many important roles in the proper functioning of the body. Though classified as a vitamin, vitamin D is actually a key regulatory hormone for calcium and bone metabolism. Adequate vitamin D status is essential for ensuring normal calcium absorption and maintenance of healthy plasma calcium levels. Beyond bone support, vitamin D also has roles in the body related to cell growth and cell signaling, muscular function, metabolic health, cognitive support, and immune health.

The liquid format allows flexible dosing from 1 to 10 drops daily as directed by a health professional. The formula is gluten-free and non-GMO.
