Sulfur is the third most abundant mineral in your body, based on percentage of total body weight.1 While close to half of it can be found in your muscles, skin and bones, sulfur plays important roles in hundreds of physiological processes.2
Sulfur bonds are required for proteins to maintain their shape, and these bonds determine the biological activity of the proteins.
For example, hair and nails consist of a tough protein called keratin, which is high in sulfur, whereas connective tissue and cartilage contain proteins with flexible sulfur bonds, giving the structure its flexibility.
With age, the flexible tissues in your body tend to lose their elasticity, leading to sagging and wrinkling of skin, stiff muscles and painful joints. A shortage of sulfur likely contributes to these age-related problems.
The Many Biological Roles of Sulfur
In addition to bonding proteins, sulfur is also required for the proper structure and biological activity of enzymes. If you don't have sufficient amounts of sulfur in your body, enzymes cannot function properly.
A cascade of health problems may thus ensue, since your metabolic processes rely on biologically active enzymes. Sulfur also plays an important role in:3
