What is Hyaluronic Acid?
Hyaluronic Acid, also known as Sodium Hyaluronate, is a substance that the human body naturally produces.
It is found in high concentrations in joints in particular. Because of this, individuals use hyaluronic acid supplements to promote joint health. However, this supplement has positive implications for skin health and healthy aging as well.
Hyaluronic Acid Benefits
Hyaluronic acid is a chief element in synovial fluid which is found in synovial joints*. These are the most common type of movable joint in the human body. The primary function of synovial fluid is to reduce friction between cartilage and synovial joints while moving. 
While more study is needed, there is great interest in hyaluronic acid and its effects on healthy aging*. The source of this attention is a rodent, the naked mole rat.
While comparative rodents live for half a decade or less, the naked mole rat can live up to 32 years. This study concluded that the abundant amount of hyaluronic acid found in this animal is responsible for its lifespan and relative health compared to other mammals. 
As far as human applications go, there is much interest in hyaluronic acid in supplementing healthy skin. While more human study is needed, the popularity of this substance as a healthy aging supplement has led many to refer to it as “the fountain of youth*.” 
Individuals should take 100mg of hyaluronic acid daily.
