Rating breakdown

Evidence for ingredient 6.0/10

Resveratrol has limited human studies on vascular and insulin parameters, but strong preclinical data.

Value for money 7.0/10

€0.60 per 200 mg is solid, especially with the added grape polyphenol mix.

Product quality 8.0/10

NOW tests for pesticides, ensures the trans-isomer, and uses vegan capsules.

Label honesty 8.0/10

Trans-resveratrol content clearly stated; source (Polygonum cuspidatum) named.

Third-party testing 6.0/10

NOW publishes internal analyses; independent tests not consistently available.

Product Description

Vegetarian capsules deliver 200 mg trans-resveratrol from Japanese knotweed plus 10 mg red wine extract and 10 mg grape skin extract to broaden the polyphenol profile and synergies.

What We Like

  • Clear specification of the trans-isomer
  • Additional polyphenols for synergy
  • Vegan capsules
  • Free from gluten, dairy, and soy

What We’re Missing

  • No public COAs available
  • Polygonum source is not organically certified

Usage Recommendation

1 capsule in the morning with a fat-containing meal. For metabolic goals, add a second capsule in the afternoon and use cyclically (5 days on, 2 days off).

Ingredient dossier

Known for sirtuin activation in animal models. Poor oral bioavailability (<1% free form) translates poorly to humans; a 2026 umbrella review found no convincing metabolic effects even in diabetics.
