Reasonable Dosing for Glutathione

When taken by mouth, most glutathione dosages range from 50 mg to 600 mg. However, it should be noted that research suggests that glutathione is not significantly absorbed into the body when taken by mouth (so it is likely that no dose of glutathione taken by mouth is effective). When inhaled, a dose of 600 mg twice daily has been recommended. When given as an intramuscular injection, a dose of 600 mg every day or every other day has been suggested by some clinical studies. A few studies that have used glutathione intravenously (IV) have used doses based on body surface area (a measure calculated using your height and weight).
