Frequently asked questions
- What is 'reduced' glutathione?
- Glutathione exists in reduced (GSH) and oxidised (GSSG) forms. The reduced form is the active antioxidant; supplements should specify 'reduced' or 'L-glutathione reduced' to indicate the active form.
- Is oral glutathione well-absorbed?
- Oral glutathione absorption has historically been a research challenge — newer formulations (liposomal, sublingual) target this. For standard oral glutathione like Jarrow's, the evidence is mixed but newer research is more positive.
- Where can I buy it?
- Amazon UK at £39.99 is the listed retailer.
- Is IGEN a banned-substance test?
- No — IGEN Non-GMO Tested verifies non-GMO sourcing only.
- When should I take it?
- Glutathione is often taken on an empty stomach, away from meals. Check the on-pack guidance for the brand's specific recommendation.
