If you’re focused on healthy aging and cellular energy, this delivers 300mg of **Nicotinamide Riboside** (NIAGEN) — above the 250mg minimum studied for raising NAD+ levels, the coenzyme your cells rely on for DNA repair and energy production. At 300mg, you're at the most common consumer dose, though clinical trials often used 1,000mg.
The secondary ingredients are where the formula falls short for you. **Trans-Resveratrol** is included at just 10mg — roughly 7% of the 150mg minimum used in clinical research. **Quercetin** comes in at 5mg, which is 1% of the 500mg studied dose. These amounts are too low to expect any measurable benefit from either compound, even with the fenugreek-based bioavailability enhancers included.
Your real value here is the NR — the resveratrol and quercetin are present in name only. If longevity polyphenols matter to you, those would need to come from a separate supplement at meaningful doses.
