What is Vitamin D


What is Vitamin D

Vitamin D is spectacularly unique because the body can source it from two radically different places — whole foods, the traditional route; and exposure to sunlight (specifically UVB rays), which triggers production in the skin.1

Vitamin D is brutally important for the absorption of calcium, which helps maintain strong teeth and bones; while deficiency leads to flimsy, brittle bones and osteoporosis. It also helps the body protect, rejuvenate, and maintain healthy skin cells; and supports nerve, muscle, and immune function.23

  • Best Sources of Vitamin D — Think SUNLIGHT, FISH & DAIRY. Milk, eggs, salmon, swordfish, oysters, tuna, sardines, yogurt, cod liver oil, and cereal are all vitamin D powerhouses.4
  • Recommended Daily Intake — Men = 600 IU/day; women = 600 IU/day.5
  • Vitamin D Deficiency — Weak bones, which can lead to rickets in children and osteomalacia/osteoporosis in adults.
