Frequently Asked Questions

What is trans-resveratrol and why is it important?

Trans-resveratrol is the active form of resveratrol found in red grape skins, red wine, and berries. It is the form that is most stable and bioavailable. Research shows it activates sirtuins (longevity proteins), has antioxidant and anti-inflammatory effects, and may support cardiovascular health, brain function, and healthy ageing.

What is ResVinol-25 and why is it used?

ResVinol-25 is a patented, standardised extract from Japanese knotweed (Polygonum cuspidatum) providing 98% pure trans-resveratrol. Japanese knotweed contains the highest natural concentration of resveratrol, making it the most practical and potent source for supplementation.

Can resveratrol help with longevity?

Research into resveratrol's longevity effects is promising but still evolving. It activates SIRT1, a sirtuin protein linked to caloric restriction pathways and healthy ageing. While definitive human longevity studies are ongoing, resveratrol is widely used as part of longevity-focused supplement stacks.

How does resveratrol compare to NMN or NR for longevity?

NMN (nicotinamide mononucleotide) and NR (nicotinamide riboside) work by boosting NAD+ levels. Resveratrol activates sirtuins that use NAD+. Some longevity researchers recommend combining resveratrol with NMN/NR for synergistic effect. They operate via complementary mechanisms.

When is the best time to take trans-resveratrol?

Trans-resveratrol is fat-soluble and absorbs best when taken with a meal containing fat. Taking it in the morning with breakfast is common. Some people take it alongside other longevity supplements for convenience.
