Best For

Pros

• ✓High-dose trans-resveratrol (500mg at 98% purity) is among the strongest single-capsule doses available
• ✓Multiple reviewers report increased energy, reduced brain fog, and faster exercise recovery
• ✓Piperine inclusion meaningfully enhances absorption of resveratrol and co-ingredients
• ✓Liposomal delivery technology improves NAD+ bioavailability compared to standard unencapsulated forms

Cons

• ✗Not third-party tested — no independent verification of label accuracy, purity, or contaminant screening
• ✗Uses direct NAD+ rather than the more clinically studied oral precursors NMN or NR, which may be better absorbed
• ✗Quercetin dose (25mg) is well below the 500–1000mg range used in standalone efficacy research
• ✗Effects take several weeks to build; one reviewer reported no perceptible benefit at all
