Curated, not stocked.
Resveratrol earns its place in our longevity category because of the mechanistic credibility behind sirtuin activation — not hype. KIKI Health uses trans-resveratrol from Japanese Knotweed, the form and source most consistently used in research. We recommend it as part of a considered longevity stack, not as a standalone fix, and always alongside a blood panel to understand your actual starting point.
About this product
Resveratrol
KIKI Health Resveratrol is a trans-resveratrol supplement derived from Japanese Knotweed, one of the most concentrated natural sources of this polyphenol. Trans-resveratrol is the biologically active form of resveratrol — the isomer studied for its role in activating sirtuins, a family of proteins associated with cellular stress response, DNA repair signalling, and longevity pathways. It is also studied for cardiovascular support, particularly its potential to help maintain healthy endothelial function and reduce oxidative stress in blood vessels.
This supplement suits those with a specific interest in longevity and NAD+ pathway support, particularly people who have already covered foundational nutrition — good diet, adequate sleep, key micronutrients — and are looking to build further. It is also relevant for those with a family history of cardiovascular concerns who want to support their heart health proactively, under guidance from their clinician.
The single-ingredient, focused formulation means you know exactly what you are taking and can stack it clearly with other protocols. Japanese Knotweed is a well-established botanical source for trans-resveratrol, favoured over grape-skin extracts for its higher and more consistent polyphenol concentration. As with most polyphenol supplements, the evidence base is still developing, but the mechanistic rationale is credible and the safety profile in healthy adults is generally well regarded.

How to use
Take 1 capsule daily, as stated on the packaging. Resveratrol is fat-soluble, so taking it alongside a meal containing some dietary fat may support absorption. Consistency over weeks to months is generally how this class of polyphenol is used.

Common questions
Frequently asked
What makes trans-resveratrol different from regular resveratrol?
Resveratrol exists in two isomeric forms: trans and cis. Trans-resveratrol is the biologically active form — the one studied for sirtuin activation, antioxidant activity, and cardiovascular effects. Many cheaper supplements use a mix of both; a trans-resveratrol-specific product like this one gives you the form with the stronger evidence base.
Who is this most likely to benefit?
It is most relevant for adults with a specific interest in longevity, cellular health, or cardiovascular support — particularly those who have already addressed foundational nutrition and are looking to extend their protocol. It is not a substitute for a balanced diet or clinically indicated treatments.
Is it safe to take alongside other supplements or medications?
Resveratrol may interact with blood-thinning medications such as warfarin or aspirin, as it has mild antiplatelet properties at higher intakes. If you are on any prescription medication, speak to your GP or pharmacist before adding this to your routine.
How long does it take to notice any effect?
Polyphenol supplements like resveratrol are not typically associated with short-term noticeable effects. Their proposed benefits — cellular resilience, cardiovascular support — operate over longer time horizons. Most people use them consistently over months as part of a broader preventive health approach.
Can I take this if I am pregnant or breastfeeding?
There is insufficient safety data on resveratrol supplementation during pregnancy or breastfeeding. We recommend avoiding it during these periods and discussing any supplementation with your midwife or GP.
