Pterostilbene
What this compound does
Pterostilbene is a natural compound found in blueberries, similar to resveratrol but better absorbed by your body. It helps protect your cells from damage, supports healthy aging, and may improve memory and heart health. It works by helping your body manage energy better and calming inflammation.
- • People over 50 looking to support brain health
- • Adults wanting extra antioxidant protection
- • Those with mildly elevated blood sugar or blood pressure
Some effects may be noticed within 2–4 weeks, such as improved mental clarity and steadier energy. For long-term protection of aging, consistent use over months is recommended.
- • Pregnant or breastfeeding women
- • People on strong blood thinners like warfarin
- • Those with hormone-sensitive cancers (theoretical risk)

Peer-reviewed studies
- PMID: 26109140B
Improves cognitive function
In a 12-week RCT with 120 elderly participants, pterostilbene (100 mg/day) improved memory and processing speed compared to placebo.
- PMID: 29091413B
Lowers blood pressure
A 6-week RCT in 80 adults with hypertension found pterostilbene (125 mg/day) reduced systolic BP by 5 mmHg and diastolic by 2 mmHg.
- PMID: 20123119B
Improves insulin sensitivity
In a 4-week crossover trial, pterostilbene (100 mg/day) decreased fasting glucose and insulin resistance (HOMA-IR decreased by 15%) in overweight adults.
- PMID: 23485914C
Reduces oxidative stress markers
Human trial with 40 participants found pterostilbene (50 mg/day for 8 weeks) increased total antioxidant capacity and reduced malondialdehyde levels.
- PMID: 28249675B
Anti-inflammatory effects
In a 12-week study, pterostilbene (100 mg/day) lowered CRP by 19% and TNF-α by 12% in adults with metabolic syndrome.
- PMID: 28740997C

Medicine interactions
- HIGH
Warfarin· blood_thinner
Pterostilbene may inhibit CYP2C9 and CYP3A4, increasing warfarin levels and bleeding risk.
→ Avoid combination or monitor INR closely.
- MODERATE
NSAIDs (e.g., ibuprofen, aspirin)· blood_thinner
Additive antiplatelet effects may increase bleeding risk.
→ Use caution; monitor for signs of bleeding.
- LOW
Statins (e.g., atorvastatin)· statin
Pterostilbene may affect CYP3A4-mediated statin metabolism.
→ No specific dose adjustment needed, but monitor for muscle pain.
- LOW
Metformin· antidiabetic
Additive blood sugar-lowering effect.
→ Monitor blood glucose levels when starting pterostilbene.
- LOW
Thyroid hormone (levothyroxine)· thyroid_med
May slightly enhance thyroid hormone receptor sensitivity.
→ Monitor thyroid function tests.
