1. What is Sulfur and Why Do We Need It?

Sulfur is a vital mineral present in every cell of your body, playing a crucial role in numerous biological processes. It’s a key component of amino acids, vitamins, and other essential molecules, contributing to everything from protein synthesis to detoxification.

1.1. The Importance of Sulfur in the Body

Sulfur is more than just a mineral; it’s a cornerstone of good health. Here’s why:
