Overview

Trans-Resveratrol is the most biologically active form of resveratrol, a natural polyphenol found in grapes, berries, and Japanese knotweed. It is renowned for its potent antioxidant properties and its ability to activate SIRT1, a key longevity gene, which helps protect the body against oxidative stress and age-related diseases.

Key Benefits

Sirtuin (SIRT1) Activation

Trans-resveratrol is a well-known activator of SIRT1, a protein that plays a crucial role in cellular health, metabolism, and longevity.

Cardiovascular Support

Its antioxidant properties help protect the cardiovascular system by reducing LDL oxidation and supporting healthy blood flow.

Potent Antioxidant

It neutralizes damaging free radicals, reducing oxidative stress throughout the body, which is a key factor in aging.

Dosage & How to Take

150-500 mg of trans-resveratrol per day.

PurposeDoseNotes
General Antioxidant Support150-250 mg/dayA standard dose for overall health maintenance.
Longevity and SIRT1 Activation250-500+ mg/dayHigher doses are often used in anti-aging protocols, sometimes in conjunction with NMN.

Best Time to Take

Can be taken anytime. Taking it with a small amount of fat (like yogurt or olive oil) can improve absorption.

With or Without Food

Recommended to be taken with food, particularly a source of fat, to enhance bioavailability.

Side Effects & Safety

Common

  • Generally well-tolerated. High doses (>1g) may cause mild gastrointestinal upset.

Rare

  • Headaches, anxiety. May have estrogenic activity, so caution is advised for hormone-sensitive conditions.

Contraindications

  • May interact with blood thinners (e.g., warfarin) and NSAIDs. Pregnant women and those with estrogen-sensitive cancers should consult a doctor.

Interactions

Blood Thinners (e.g., Warfarin, Aspirin)Moderate

May increase the risk of bleeding due to its anti-platelet activity.

CYP450 SubstratesModerate

Resveratrol can inhibit certain CYP enzymes, potentially affecting the metabolism of various medications.

Scientific Research

2003Nature

Resveratrol as a sirtuin activator

Studies have shown that resveratrol can directly activate SIRT1, leading to downstream effects that mimic some of the benefits of calorie restriction.

2015International Journal of Cardiology

Effects of resveratrol on cardiovascular health

A meta-analysis concluded that resveratrol supplementation can significantly improve systolic blood pressure and other cardiovascular markers.
