Understanding Glutathione & Supplement Forms
Glutathione exists in reduced (active) and oxidized forms. Supplementation aims to increase reduced glutathione levels. Common forms include:
- L-Glutathione: The most common form, directly usable by the body.
- N-Acetyl Cysteine (NAC): A precursor to glutathione, helping the body produce it.
- Setria® Glutathione: A clinically studied, highly bioavailable form of L-Glutathione.
- Liposomal Glutathione: Encapsulated in liposomes for enhanced absorption.
