Hyaluronic acid (HA) – In body

Hyaluronic acid (HA) is a naturally occurring substance found in various tissues throughout the body, with the highest concentrations typically found in connective tissues, skin, and eyes. It’s produced by specialized cells called fibroblasts in the skin, as well as by other cells in the body.

Here are some of the primary sources of hyaluronic acid in the body:

1. Skin: The skin contains a significant amount of hyaluronic acid, where it plays a crucial role in maintaining hydration and elasticity.
2. Connective Tissues: HA is present in connective tissues such as cartilage and synovial fluid, where it helps lubricate joints and cushion tissues.
3. Eyes: In the eyes, hyaluronic acid is found in the vitreous humor, a gel-like substance that helps maintain the shape of the eye and provides nutrition to the cells.
4. Other Tissues: Hyaluronic acid is also found in other tissues throughout the body, including the umbilical cord, where it helps facilitate fetal development.

Overall, hyaluronic acid is a vital component of the extracellular matrix, providing structure, hydration, and support to various tissues and organs.
