Ca-AKG vs Glutathione
A side-by-side research comparison of Ca-AKG and Glutathione across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Ca-AKG | Glutathione |
|---|---|---|
| Full name | Calcium Alpha-Ketoglutarate | L-Glutathione (Reduced) |
| Category | Anti-Aging | Anti-Aging |
| Status | Dietary compound (research ongoing) | Supplement / Injectable |
| Mechanism | Alpha-ketoglutarate is a key TCA-cycle intermediate and a cofactor for enzymes involved in energy metabolism, collagen synthesis, and epigenetic regulation (it influences DNA/histone demethylases). Supplementation aims to restore age-related declines. | Directly neutralizes free radicals, regenerates vitamins C and E, supports phase II liver detoxification, maintains cellular redox balance, and protects mitochondrial DNA. |
| Molecular weight | ~204 Da (AKG portion) | 307.32 Da |
| Half-life | Short; rapidly metabolized | ~1.5-2 hours (IV/IM) |
| Bioavailability | Oral | ~95% injectable; low oral (~3%) |
| Typical dose | 1-3 g per day | 200-600 mg |
| Frequency | 1-2x daily | 1-3x per week |
| Route | Oral | IV push, IM injection, or nebulized |
