In 2008, the American Academy of Pediatrics doubled its vitamin D recommendations for infants, children, and adolescents to 400 I.U.s a day in response to the growing recognition of vitamin D deficiency as an epidemic1. For children and adults who do not receive adequate sun exposure, experts recommend a minimum of 1000 I.U.s daily. Best known for its role in building and maintaining strong bones, vitamin D also helps regulate the immune and neuromuscular systems, and is key to optimizing health1. The recommended form of vitamin D is D3 (or cholecalciferol), the natural and most easily absorbed form, which the body makes from sunlight. Nordic Naturals Vitamin D3 is in a carrier oil of organic extra virgin olive oil, which is rich in the “heart-healthy” omega-9, oleic acid.
