Hyaluronic acid (HA) is an important glycosaminoglycan, present in epithelial and connective tissues. It is moreover a key component in joints cartilage, with the role of coating chondrocytes
and letting water be attracted and imbibe the surrounding area, conferring to cartilage the typical elasticity and resistance to compression.
It is also part of synovial fluid, filling spaces in the joints, nurturing non-vascolarized tissues and lubricating joints. Supplemented HA (in a wide range of molecular weight, leading
to different capabilities to penetrate tissues) is thus helpful to healthy joints, besides its classical role in maintaining skin elasticity and favoring epithelization.
