Inside the formula
The dose now matches the label: 600mg, not 1,200mg.
This correction matters. Each capsule supplies 600mg of 98% pure trans-resveratrol from Japanese knotweed root, and the product title, description and evidence now say the same thing.

Human evidence · systematic review
The stilbene polyphenol
Trans-Resveratrol
98% pure · from Polygonum cuspidatum root
What it is: Resveratrol is a stilbene found in several plants. This product uses the trans isomer sourced from Japanese knotweed root rather than wine.
Evidence context: A recent systematic review of clinical trials found diverse study designs and outcomes. The literature does not support a universal anti-aging or heart-treatment claim.
How it fits the formula
Explore the clinical reviewA single 600mg active with declared source and purity makes the formula more transparent than the previous, incorrect 1,200mg page title.
Every other label-listed ingredient
What the supporting ingredients actually do.
Rice flour
An inactive carrier used to support consistent capsule fill.
Cellulose capsule
The plant-derived capsule shell.
The formulation rationale
Source, purity and dose in agreement.
Trans isomer + 98% purity: The label defines both chemical form and purity, improving interpretation of the 600mg amount.
Botanical source + isolated compound: Japanese knotweed is the source; the declared active is purified trans-resveratrol rather than whole-root powder.
Large literature + modest certainty: Many trials exist, but varied methods and mixed outcomes prevent sweeping clinical conclusions.

- What It Does
Each capsule provides 600mg of 98% pure trans-resveratrol sourced from Polygonum cuspidatum (Japanese knotweed) root.
- How It Works
Trans-resveratrol is absorbed and rapidly metabolized. Clinical studies vary widely in formulation, dose, population and outcome, so the evidence does not support universal heart-health, anti-aging or therapeutic claims.
- Science-Backed Research
Evidence tier is identified for each active ingredient
Human, preclinical and formulation evidence are kept separate
Primary-source research is linked in the ingredient breakdown
The exact finished formula is not presented as clinically tested
- Ideal For
Shoppers comparing clearly declared active amounts

Systematic review of resveratrol clinical trials
The review found a broad but heterogeneous clinical literature. Findings depend on the outcome and study design and do not establish a consensus therapeutic use.
