Resveratrol
Also known as: Trans-resveratrol, Polygonum cuspidatum extract
Resveratrol is a polyphenol found in grapes, red wine, and certain plants, and it is widely discussed in healthy-aging and heart-wellness contexts. It is important to be honest here: results in human studies have generally been much weaker and more mixed than the striking effects seen in laboratory and animal research, partly because the body absorbs and processes it quickly. Interest remains high, but the human evidence does not match the hype.

🧭 Caution level
Ask a clinician or pharmacist before use.
- Bleeding / surgery caution category
- Anticoagulant (blood thinner) interaction
- Antiplatelet interaction
- Evidence not fully source-reviewed yet
Caution level is an informational summary of commonly discussed caution categories and doses — not a safety rating, approval, or medical advice. Low caution does not mean safe for you.
🩺 Medication caution categories
- Blood thinners (anticoagulants)
- Antiplatelet medication
🏥 Surgery & procedure caution
Because it is sometimes discussed in relation to bleeding, talk to a qualified healthcare professional about your full supplement list well before any scheduled procedure.
If you have a procedure scheduled, bring your full supplement list to your surgical and anesthesia team. Do not stop prescribed medication unless your clinician tells you to. Do not start or stop supplements based only on this app.
✅ Quality checklist
- Prefer products with third-party testing or a certificate of analysis (COA).
