What is hyaluronic acid?

Hyaluronic acid is a mucopolysaccharide that is part of a family called the glycosaminoglycans. These long-chain sugar molecules appear naturally in cell membranes throughout the human body, and help with hydration of tissues and other important cell functions. For supplementation, hyaluronic acid may be produced using animal sources, but can also be isolated from fermented bacteria.^[1]
