Fisetin vs Glutathione
A side-by-side research comparison of Fisetin and Glutathione across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Fisetin | Glutathione |
|---|---|---|
| Full name | Fisetin (Senolytic Flavonoid) | L-Glutathione (Reduced) |
| Category | Anti-Aging | Anti-Aging |
| Status | Dietary compound (research ongoing) | Supplement / Injectable |
| Mechanism | Acts as a senolytic by tipping senescent cells toward apoptosis (programmed death) while sparing healthy cells. Also has antioxidant and anti-inflammatory activity. | Directly neutralizes free radicals, regenerates vitamins C and E, supports phase II liver detoxification, maintains cellular redox balance, and protects mitochondrial DNA. |
| Molecular weight | 286.24 Da | 307.32 Da |
| Half-life | Short; poor baseline absorption (often taken with fat) | ~1.5-2 hours (IV/IM) |
| Bioavailability | Low oral; improved with lipids/liposomal forms | ~95% injectable; low oral (~3%) |
| Typical dose | ~20 mg/kg on hit days (protocol-dependent) | 200-600 mg |
| Frequency | Intermittent "hit and run" courses | 1-3x per week |
| Route | Oral | IV push, IM injection, or nebulized |
