Size: 50 grammes Hyaluronic acid (sodium hyaluronate) is sometimes referred to as nature’s moisturiser due to its use as a bodily lubricant and the fact that it is one of the most hydrophilic naturally occurring molecules. It keeps the joints of the human body well lubricated so that in the event of heavy exercise, the bones do not begin rubbing together and causing damage to one another. Not only that, but hyaluronic acid also has an effect on the way injury is handled by the body. It is the presence of hyaluronic acid that stops painful joints from occurring. Low levels of HA will eventually cause joint pain if it is not supplemented.
