Pure Encapsulations Hyaluronic Acid or HA, is a naturally occurring polymer found in every tissue of the body. It is particularly concentrated in the skin (almost 50% of all HA in the body is found in the skin) and synovial fluid. It is composed of alternating units of n-acetyl-d-glucosamine and d-glucuronate. This polymer’s functions include attracting and retaining water in the extracellular matrix of tissues, in layers of skin, and in synovial fluid.
For joints, HA is especially supportive of healthy lubrication and shock absorption. Furthermore, in vitro studies indicate that HA modulates prostaglandin production, providing additional support forjoint function.
