Sulfur (S) – a Macroelement

Sulfur is an essential macroelement that plays a vital role in the human body. It is involved in many important functions, including metabolism, immune system function, and skin health. In this article, we will explore the functions of sulfur in the body, its sources, and the potential health benefits and risks associated with its consumption.

Functions of Sulfur in the Body

Sulfur is involved in many important functions in the body. It is a component of several amino acids, including cysteine and methionine, which are essential for protein synthesis.
