Quercetin vs TUDCA
A side-by-side research comparison of Quercetin and TUDCA across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Quercetin | TUDCA |
|---|---|---|
| Full name | Quercetin (Flavonoid Senolytic) | Tauroursodeoxycholic Acid |
| Category | Detox & Antioxidant | Detox & Antioxidant |
| Status | OTC supplement | OTC supplement / Investigational |
| Mechanism | 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. | Acts as a chemical chaperone that reduces endoplasmic reticulum (ER) stress, inhibits apoptosis, protects mitochondria, improves bile flow and solubility, and provides neuroprotective and cytoprotective effects. |
| Molecular weight | 302.24 Da | 571.81 Da |
| Half-life | ~11-28 hours | Variable (enterohepatic recirculation) |
| Bioavailability | Low; improved by phytosome/bromelain formulations | Moderate oral |
| Typical dose | 500-1000 mg per day (daily) or high-dose pulsed (senolytic) | 250-500 mg per day |
| Frequency | Daily or intermittent | 1-2x daily |
| Route | Oral capsule | Oral capsule |
