  • Antioxidant mineral found in major structural molecules of the body such as cartilage.

Sulfur is an essential mineral found in the cartilage and similar structural tissues. It usually acts as an antioxidant and is responsible for the production of glycosaminoglycans, which are highly concentrated and are found around the connective tissues such as skin, collagen and joint cartilage.

Sulfur is an important mineral for healthy skin, nails, and hair. It also sustains oxygen balance for proper brain function.
