Vitamin D3 the natural form of vitamin D, one of the few vitamins your body makes itself rather than requiring through diet. It's a fat-soluble vitamin, meaning you need a proper amount of dietary fat to fully absorb it into your bloodstream. When ultraviolet light hits your skin, the liver and kidneys produce vitamin D3. It has several health benefits, aiding in bone growth and density, and bone health. However, up to nine percent of adults in the U.S. are vitamin D-deficient, and this deficiency can lead to several health concerns.
Vitamin D3 promotes calcium absorption in your gut, enabling your body to maintain adequate levels of calcium and phosphate concentrations for proper bone mineralization. Poor bone mineralization causes small holes in the bones that can become larger; this is known as osteoporosis and can lead to brittle bones that break easily. Vitamin D3 is also needed for bone growth. Receiving between 800-5000 IU of vitamin D3 per day can improve musculoskeletal health by naturally retarding the breakdown and aging of the skeletal structure.
