Vitamin D is an essential nutrient/hormone for optimal brain health. Vitamin D is actually not a vitamin but a prohormone or hormone building block. Vitamins by definition are provided through food and the primary source of Vitamin D is UVB rays from the sun. A small amount is available through food sources. Vitamin D deficiency is an epidemic associated with many health conditions such as depression, insomnia, fatigue, multiple cancers, autism and multiple sclerosis.
