PQQ vs TUDCA
A side-by-side research comparison of PQQ and TUDCA across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | PQQ | TUDCA |
|---|---|---|
| Full name | Pyrroloquinoline Quinone (BioPQQ) | Tauroursodeoxycholic Acid |
| Category | Detox & Antioxidant | Detox & Antioxidant |
| Status | Dietary supplement (GRAS) | OTC supplement / Investigational |
| Mechanism | Activates PGC-1α (master mitochondrial biogenesis regulator) via CREB phosphorylation. Catalytic antioxidant that undergoes 20,000+ redox cycles vs one-time use of vitamin C. Stimulates NGF synthesis for neuroprotection. | 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 | 330.21 Da | 571.81 Da |
| Half-life | ~3-5 hours | Variable (enterohepatic recirculation) |
| Bioavailability | ~60% oral | Moderate oral |
| Typical dose | 10-20 mg | 250-500 mg per day |
| Frequency | Daily | 1-2x daily |
| Route | Oral capsule | Oral capsule |
