While the body produces glutathione naturally, you can support its synthesis by eating sulfur-rich foods (e.g., broccoli, garlic, onions, and eggs) and getting adequate vitamins like folate and B12. [1]

Because oral glutathione is often broken down in the digestive tract before reaching the bloodstream, healthcare providers sometimes use alternative delivery methods. You can learn more about clinical applications through resources like the Healthline Overview of Glutathione or review medical definitions on the National Cancer Institute Drug Dictionary. [1, 2, 3]
