What is the recommended dosage for Resveratrol?

General: 150-500 mg/day; Cardiovascular Support: 250-500 mg/day trans-resveratrol

What are the side effects of Resveratrol?

Potential side effects include: Gastrointestinal discomfort (nausea, diarrhea, cramping) at high doses, Headache, May have estrogenic activity at high doses.

What is resveratrol and how may it support cardiovascular health?

Resveratrol is a polyphenol found in red grape skins, red wine, and Japanese knotweed. It has shown cardioprotective effects in laboratory studies through antioxidant, anti-inflammatory, and endothelial-protective mechanisms. Human clinical trials show some benefits for blood pressure and lipid profiles, but evidence for cardiovascular event reduction is lacking.

What dosage of resveratrol has been studied for cardiovascular health?

Clinical studies have used 75–500 mg of resveratrol per day. A meta-analysis found blood pressure benefits at doses above 150 mg daily. Bioavailability is a challenge, as resveratrol undergoes extensive first-pass metabolism. Trans-resveratrol is the more bioactive isomer. Study durations ranged from 4 to 24 weeks.

What are the potential side effects of resveratrol?

Common side effects include gastrointestinal discomfort, nausea, and diarrhea at higher doses. Resveratrol may have estrogenic activity and should be used cautiously with hormone-sensitive conditions. It may interact with blood thinners, NSAIDs, and drugs metabolized by CYP enzymes. No serious adverse events have been reported in clinical trials.

About

Resveratrol is a polyphenolic stilbene that activates SIRT1 and AMPK pathways, enhances endothelial nitric oxide production, and inhibits LDL oxidation. A 2015 meta-analysis of 10 RCTs found resveratrol at >=150 mg/day reduced systolic blood pressure by 11.9 mmHg in hypertensive patients. Bioavailability remains a challenge due to rapid hepatic metabolism.

How It Works

Activates SIRT1 and AMPK pathways enhancing mitochondrial biogenesis; potent inhibitor of LDL oxidation and foam cell formation; enhances endothelial nitric oxide synthase (eNOS) expression improving vasodilation; inhibits platelet aggregation through COX-1 and thromboxane A2 pathways; anti-inflammatory via NF-kB suppression.
