Micronutrients & recovery
Daily oral supplementation with NRPT (250mg Nicotinamide Riboside + 50mg Pterostilbene) significantly increases whole blood NAD+ levels by approximately 40% in healthy adults aged 60-80 over an 8-week period.
Take 250mg of Nicotinamide Riboside combined with 50mg of Pterostilbene once daily with breakfast. This specific combination has been shown in a clinical trial of adults aged 60-80 to safely and sustainably raise NAD+ levels by about 40% over two months without serious side effects.
NAD+ levels increased by approximately 40% in the NRPT 1X group... after 4 weeks as compared to placebo and baseline. Furthermore, this significant increase in NAD+ levels was sustained throughout the entire 8-week trial.
Why this rating
Randomized, double-blind, placebo-controlled human trial with a moderate sample size (n=120) and clear statistical significance, though limited to a specific age demographic.
