Glutathione supports detoxification processes in the human body.

Caveats

• The claim applies to endogenous glutathione produced by the body; oral glutathione supplements face significant bioavailability limitations and may not reliably raise intracellular levels.
• While the mechanistic evidence for glutathione's detoxification role is robust, direct clinical evidence that altering glutathione levels meaningfully improves measurable toxin clearance in humans is more limited.
• Several lower-authority sources in the evidence pool come from supplement retailers and wellness clinics with financial conflicts of interest — the claim's validity rests on the peer-reviewed literature, not commercial sources.
