It provides the entirety of strength and the structure of all connective tissues and is found in all skin, muscles, tendons and bones. Collagen plays numerous important roles in the human's body health and appearance. Skin, hair and nails are all dependent on collagen production to maintain a beautiful and healthy appearance.The natural aging process breaks down and depletes the body's natural collagen and as collagen decreases, negative health and cosmetic conditions increase. Collagen supplementation has been shown to heal, repair and even reverse the natural effects of aging caused by the decrease of collagen production.
