Glutathione vs Klotho
A side-by-side research comparison of Glutathione and Klotho across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Glutathione | Klotho |
|---|---|---|
| Full name | L-Glutathione (Reduced) | Klotho Protein |
| Category | Anti-Aging | Anti-Aging |
| Status | Supplement / Injectable | Research compound (preclinical/early) |
| Mechanism | Directly neutralizes free radicals, regenerates vitamins C and E, supports phase II liver detoxification, maintains cellular redox balance, and protects mitochondrial DNA. | Exists in membrane-bound and soluble forms. Soluble Klotho acts as a circulating hormone that modulates FGF23 signaling, regulates phosphate/vitamin D balance, suppresses certain growth and oxidative-stress pathways, and supports synaptic and cognitive function. |
| Molecular weight | 307.32 Da | ~130 kDa (full protein; fragments studied) |
| Half-life | ~1.5-2 hours (IV/IM) | Not well established for therapeutic forms |
| Bioavailability | ~95% injectable; low oral (~3%) | Injectable in research; large protein with limited oral absorption |
| Typical dose | 200-600 mg | No established human dose |
| Frequency | 1-3x per week | Unknown |
| Route | IV push, IM injection, or nebulized | Injection (research) |
