Best Pterostilbene Supplements 2026
Pterostilbene is a natural stilbene compound found in blueberries and grapes that is structurally similar to resveratrol but with significantly higher bioavailability (up to 80% vs. resveratrol's ~1%). It activates sirtuins, inhibits inflammatory pathways, and has superior brain penetration. Research suggests benefits for cognitive aging, blood sugar management, cardiovascular health, and longevity pathways.
Key benefits
- Sirtuin activation (longevity pathways)
- Superior bioavailability vs resveratrol
- Cognitive function and neuroprotection
- Blood glucose and insulin sensitivity
- Anti-inflammatory (NF-ÎșB inhibition)
Research rating & citations
Research quality is summarized from public evidence and NIH resources. Always interpret findings within the context of your personal health needs.
Side effects
- LDL increase at high doses (>250mg/day) in some studies
- Drug interactions (CYP2B6 inhibition)
- Generally well tolerated at 50-150mg
- May lower blood pressure
Dosage guide
The typical range is 50-150mg daily; often 50mg with NMN or resveratrol. Start at the low end, take with food if needed, and review interactions before combining products.

NMN (Nicotinamide Mononucleotide)
NMN is a precursor to NAD+, a coenzyme essential for cellular energy production and DNA repair. Research suggests NMN supplementation may support healthy NAD+ levels that naturally decline with age, with emerging evidence for longevity and metabolic health support.
Top benefits
- NAD+ precursor
- Cellular energy support

NAD+ (Nicotinamide Adenine Dinucleotide)
NAD+ is a coenzyme central to energy metabolism, DNA repair, and cellular signaling that declines significantly with age. Oral NAD+ precursors (NMN, NR) and direct NAD+ supplements aim to raise cellular NAD+ levels to support energy, longevity, and cognitive function. Human research is actively growing.

Grape Seed Extract
Grape seed extract (GSE) is rich in oligomeric proanthocyanidins (OPCs) â potent antioxidants that exceed vitamin C and E in free radical scavenging capacity. Research demonstrates meaningful cardiovascular benefits including blood pressure reduction, LDL oxidation protection, and improved endothelial function. Also studied for venous insufficiency, wound healing, and cognitive aging.
Top benefits
- Blood pressure reduction (endothelial nitric oxide support)
