Glutathione (IV/IM) vs Quercetin
A side-by-side research comparison of Glutathione (IV/IM) and Quercetin across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Glutathione (IV/IM) | Quercetin |
|---|---|---|
| Full name | L-Glutathione (Reduced, Injectable) | Quercetin (Flavonoid Senolytic) |
| Category | Detox & Antioxidant | Detox & Antioxidant |
| Status | Compounded / Prescription | OTC supplement |
| Mechanism | Directly conjugates with toxins, heavy metals, and reactive oxygen species via glutathione S-transferases. Regenerates vitamins C and E. Maintains thiol redox status. Supports Phase II liver detoxification. | Selectively induces apoptosis in senescent cells by inhibiting pro-survival (SCAP/BCL) pathways, especially when paired with dasatinib. Also scavenges free radicals, inhibits mast-cell histamine release, and modulates NF-kB inflammatory signaling. |
| Molecular weight | 307.32 Da | 302.24 Da |
| Half-life | ~2-3 hours (IV bolus) | ~11-28 hours |
| Bioavailability | 100% (IV); ~60% (IM); ~5-10% (oral) | Low; improved by phytosome/bromelain formulations |
| Typical dose | 600-2000 mg IV push or 200-600 mg IM | 500-1000 mg per day (daily) or high-dose pulsed (senolytic) |
| Frequency | 1-3x weekly | Daily or intermittent |
| Route | Intravenous push or intramuscular injection | Oral capsule |
