Options compared
Sorted by how people usually approach this goal. “Why people stop” is included because the reason a supplement gets abandoned is usually more useful than its best-case claim.
| Option | Best for | Onset | Evidence | Risk | Why people stop |
|---|---|---|---|---|---|
| Resveratrol | Sirtuin pathway activation and antioxidant support | Weeks to months | Limited in humans, strong preclinical cellular longevity markers | Low to moderate | Subjective feedback is missing; long-term bet |
| CoQ10 | Anti-aging mitochondrial support and cardiovascular health | 2 to 8 weeks | Moderate for cardiovascular markers and cellular recovery | Low | Requires daily consistency to maintain tissue levels |
| Quercetin | Senolytic aging support and seasonal histamine response | Days to weeks | Limited for human longevity endpoints, moderate for immune/allergy support | Low | Low oral absorption rates in standard powders |
Resveratrol
Avoid if: Estrogen-sensitive conditions (phytoestrogen effect)
Form: Trans-resveratrol capsules
CoQ10
Avoid if: Blood clotting medications without monitoring
Form: Ubiquinol or water-soluble CoQ10 formulation
Quercetin
Avoid if: Severe kidney disease without clinician check
Form: Quercetin phytosome or paired with bromelain
