Vitamin D is a steroid vitamin, a group of fat-soluble pro-hormones best known for their role in supporting bone health and aiding in the absorption of calcium and phosphate from the gastrointestinal (GI) tract. It is a key nutrient for the needs of growing children and adolescents. A growing body of research highlights its important role in supporting other body systems, cardiovascular health, musculoskeletal strength, and immune function. It can target over 200 different genes throughout the body. Despite its importance, deficiency and insufficiency of this important nutrient has reached epidemic proportions around the world, in both adults and children.
