Consume Sulfur-Rich Foods

In some plant and protein-based foods, sulfur is an essential mineral that occurs naturally. Important proteins and enzymes in the body need it for their structure and function. Notably, glutathione can only be made with sulfur.

Methionine and cysteine are two amino acids that contain sulfur in food. It primarily comes from dietary sources of proteins such as beef, fish, and poultry. The cruciferous vegetable broccoli, Brussels sprouts, cauliflower, kale, watercress, and mustard greens are among vegetarian sources of sulfur. Studies on both humans and animals have found that eating plants high in sulfur may lessen oxidative stress by raising glutathione levels. Additionally, allium foods such as garlic, shallots, and onions increase glutathione levels, possibly due to the sulfur-containing compounds they contain.
