Sulfur is a mineral that, while often overlooked, is essential to numerous biological processes in the body. It is a component of amino acids, which are the building blocks of proteins, and plays a role in enzyme function. Sulfur is vital for maintaining the structural integrity of various tissues, such as hair, skin, and nails. It is also involved in cellular detoxification. Sulfur is found in dietary sources like garlic, onions, and cruciferous vegetables. While sulfur deficiency is rare, understanding its importance in supporting healthy cellular function and tissue structure is integral to overall well-being.
