Benefits of Hyaluronic Acid Products and supplements

Hyaluronic acid is found in the synovial joint fluid, the vitreous humor of the eye, the cartilage, blood vessels, extracellular matrix, skin and the umbilical cord.

Restylane is a gel of hyaluronic acid produced by bacteria and used for treating facial wrinkles and folds. Hyaluronic acid is a substance that is normally produced by the body. Hyaluronic acid is what gives skin its volume and fullness.

As Hyaluronic Acid is present in every tissue of the body; hyaluronic acid's importance cannot be underestimated. Retention of water is one of the most important biological functions of hyaluronic acid, 1 second only to providing nutrients and removing waste from cells that do not have a direct blood supply, such as cartilage cells. With a lower than adequate amount of hyaluronic acid, nutrients cannot be moved into these cells and waste cannot be eliminated from cells. Hyaluronic acid is sometimes abbreviated as HA.

Hyaluronic acid has been approved by the FDA. It can be administered only by a qualified provider in a series of injections as mentioned above. Most insurance companies are currently paying for these injections, after traditional and conservative measures have been attempted.

It is well documented that fetal tissues contain large amounts of Hyaluronic Acid and that decreasing Hyaluronic Acid content correlates with aging and wrinkling. Therefore practical attempts to prolong and recapture youth by revitalizing damaged tissue should include this molecule.

In summary, hyaluronic acid injections have been found to be beneficial in osteoarthritic knees. There is no explanation as to why some individuals react positively when others do not. However, it has been found that 80 to 85% of individuals who are treated with this series of injections have some amount of pain relief which lasts anywhere from nine to 12 months. This series of injections can be repeated if necessary, though the understanding and reasoning for repeat series of injections has not been clearly defined yet.
Hyaluronic acid and Body

Its function in the body is, amongst other things, to bind water and to lubricate movable parts of the body, such as joints and muscles. Its consistency and tissue-friendliness allows it to be used in skin-care products as an excellent moisturizer. Hyaluronic acid is one of the most hydrophilic (water-loving) molecules in nature and can be described as "nature's moisturizer".
Hyaluronic acid and Eyes

Hyaluronic acid is highly concentrated inside the eyeball. The fluid inside the eye called the vitreous humor is composed almost completely of hyaluronic acid.  The HA gives the fluid inside the eye a viscous gel like property.
