Sulfur is an essential mineral involved in the synthesis of key amino acids like methionine and cysteine, playing a foundational role in building proteins, enzymes, and antioxidants such as glutathione. Methylsulfonylmethane (MSM) is the most widely studied supplemental form, and research suggests it may help support joint comfort and mobility, particularly in individuals with osteoarthritis, likely through its anti-inflammatory and antioxidant properties. Studies also indicate that sulfur-containing compounds contribute to the structural integrity of connective tissues, which is why adequate sulfur intake is often associated with healthy hair, skin, and nails. Sulfur-rich foods such as cruciferous vegetables, garlic, onions, and eggs provide naturally bioavailable forms of this mineral, supporting the body's detoxification pathways and overall cellular function.
