Hyaluronic Acid – Content, Location and Functions in Human Body
Hyaluronic Acid (HA) is found in almost every cell in the human body and occurs in the highest concentrations in several specific body locations. The average Hyaluronic Acid in our bodies is estimated to be around 15 grams. It is distributed in almost every part of the body and has multiple functions. It is a well-proven fact that HA improves skin hydration, and elasticity while stimulating skin collagen production. In addition, it performs antioxidant and free radical protection, as well as cushioning joints and nerve tissues. It has also been confirmed that it possesses antibacterial and anti-inflammatory characteristics.
Nearly 50 % of the body’s HA is located in the collagen of skin and lips. Cosmetic grade hyaluronic acid is an excellent skin moisturizer and its properties and functions contribute to the increased smoothness and reduced wrinkling. It is also present in the joints – it acts as a shock absorber lubricating the fluid in the joint tissues.
HA is also claimed to remove or neutralize metabolic waste products resulting from the destruction of the cartilage, thus bringing relief from severe joint pain. This really omnipresent compound is a vitally important component of the human eye located in the vitreous fluid, where its content is reaching almost 80%. Beneficial effects have been reported of the supplementation with this substance on eye tissues, especially for people suffering from dry eyes. Medical grade hyaluronic acid is a substantial connective tissue component in the gums playing important roles in the regeneration of the gum tissue and reducing any inflammation that leads to bleeding gums. Recent research shows that the throat and other mucous membranes have large concentrations of HA.
Hyaluronic Acid is widely present in the connective tissue (tendons, ligaments, etc.) found everywhere in the body. Its major functions here are binding, support, protection, and insulation. It is located as well in scalp and hair follicles, nourishing and hydrating the tissue which gives rise to hair.
Is it not incredible that the high presence of hyaluronic acid is found even in the fetal tissues! There it forms a very special substance in which embryonic cells have the perfect environment to develop and multiply rapidly. Could one light-heartedly say it is not essential to life?
