Does Pterostilbene Help With Pterostilbene is a natural polyphenol found in blueberrie...?

Evidence Summary

Pterostilbene is a natural polyphenol found in blueberries and grapes, and a close chemical cousin of resveratrol — but with better absorption and metabolic stability. In human trials, it has been studied mostly in combination with nicotinamide riboside (NR), where the pair showed modest reductions in liver enzyme markers (ALT and GGT) in people with fatty liver disease, and helped raise NAD+ levels in patients with acute kidney injury. Short-term use at doses of 10–200 mg/day appears safe with no reported adverse events, but most exciting findings — anti-cancer, anti-inflammatory, joint protection — come from lab and animal studies, not human trials.
