Glutathione
Also known as: GSH, reduced glutathione
Glutathione is the main intracellular antioxidant, made by the body from cysteine, glycine and glutamate. When taken by mouth, part of it is broken down in the gut, so its effect is uncertain.
What it is used for
- Raising blood glutathione – weak to moderate evidence with long-term use
- Liver support – weak evidence
- Skin lightening – weak evidence
Forms and how they differ
reduced glutathione (GSH)
common capsule form
liposomal glutathione
meant to improve absorption; evidence is limited
S-acetyl glutathione
more stable form, few studies
precursors (NAC + glycine)
cheaper option to support your own production
Pairs well with
Works well with vitamin C and selenium.
Do not combine / separate
During chemotherapy, do not combine with antioxidants without your oncologist's approval.
Watch out for
Not recommended in pregnancy or breastfeeding due to lack of data. If you have asthma (inhaled forms), are in cancer treatment, have liver or kidney disease or take medicines, consult your doctor.
