Glutathione vs NMN
A side-by-side research comparison of Glutathione and NMN across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Glutathione | NMN |
|---|---|---|
| Full name | L-Glutathione (Reduced) | Nicotinamide Mononucleotide |
| Category | Anti-Aging | Anti-Aging |
| Status | Supplement / Injectable | Dietary compound (research ongoing) |
| Mechanism | Directly neutralizes free radicals, regenerates vitamins C and E, supports phase II liver detoxification, maintains cellular redox balance, and protects mitochondrial DNA. | NMN is converted to NAD+ via the NAD+ salvage pathway (through NMNAT enzymes). Higher NAD+ supports sirtuin activity, PARP-mediated DNA repair, and mitochondrial energy metabolism. |
| Molecular weight | 307.32 Da | 334.22 Da |
| Half-life | ~1.5-2 hours (IV/IM) | Short; rapidly taken up and converted to NAD+ |
| Bioavailability | ~95% injectable; low oral (~3%) | Oral absorption reported; sublingual and injectable forms also used |
| Typical dose | 200-600 mg | 250-1000 mg per day |
| Frequency | 1-3x per week | Once daily |
| Route | IV push, IM injection, or nebulized | Oral (capsule/sublingual) |
