NAD+ vs Taurine
A side-by-side research comparison of NAD+ and Taurine across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | NAD+ | Taurine |
|---|---|---|
| Full name | Nicotinamide Adenine Dinucleotide (NAD+ / NMN / NR) | Taurine (2-Aminoethanesulfonic Acid) |
| Category | Anti-Aging | Anti-Aging |
| Status | Research compound | OTC supplement |
| Mechanism | NAD+ serves as cofactor for sirtuins (SIRT1-7), PARPs (DNA repair), and CD38. Declining NAD+ impairs mitochondrial function and epigenetic maintenance. Restoration reactivates longevity pathways. | Acts as a cytoprotective osmolyte and antioxidant, stabilizes mitochondrial function, modulates calcium signaling and GABA-A/glycine receptors, reduces inflammation, and supports bile acid conjugation. Taurine deficiency accelerates cellular senescence markers. |
| Molecular weight | 663.4 Da | 125.15 Da |
| Half-life | 1-4 hours (IV), 4-8h (oral precursors) | ~1 hour (plasma) |
| Bioavailability | 100% (IV), variable (oral 5-30%) | ~90-100% oral |
| Typical dose | 250-500mg IV or 500-1000mg NMN oral | 1-6 g per day |
| Frequency | Weekly (IV) or Daily (oral) | 1-3x daily |
| Route | IV infusion or Oral (precursors) | Oral (powder or capsule) |
