Sirtuins Power Your Longevity Pathway
Resveratrol activates sirtuins — the protein family behind cellular stress defence, gene regulation and healthy ageing.
Not All Resveratrol Is Created Equal
Nature produces two isomers. Only the trans form is biologically active in research. The cis form is essentially inert.

Why Eternal Resveratrol™
Ultra High Purity
We source over 99% pure trans resveratrol and over 95% quercetin to ensure you have the highest quality possible.
Clean & Consistent
Made with controlled ingredients to reduce impurities and cross contamination.
Zero Fillers
There are zero fillers or binders used, which is very uncommon when buying resveratrol. We only use pure active ingredients.
Paired With Quercetin
Both active ingredients are polyphenols, seen in nature together and often studied together in scientific research.
Compliant & Controlled
Developed with full FSA compliance in mind for clear sourcing, proper labelling and robust quality checks.
Resveratrol Vs Other Supplements
When developing Eternal Resveratrol we struggled to find any products that had the full 150mg dose of ultra pure trans resveratrol, zero fillers, 3rd party lab tested (with downloadable reports) and manufactured in the UK to GMP standards.

FAQ
Common Questions
It’s completely up to you - choose a time that fits your routine.
Many customers prefer to take Eternal Resveratrol™ in the morning, but it can be taken at any time of day.
Be sure to take it with food, ideally something fatty.
Trans resveratrol is a well known plant derived polyphenol that is widely studied in scientific research and often used in supplement form.
Resveratrol exists in two forms: cis and trans.
Trans resveratrol is the form most commonly used in supplements and scientific research because it has a more stable structure.
When a label says “trans resveratrol,” it refers specifically to this preferred isomer, while “resveratrol” on its own may include a mixture of both forms.
To produce a filled capsule we have to add something as 150mg of trans resveratrol would leave too much space.
Many products out there use a filler, however we did not want to use fillers.
Instead, we found a complimentary active ingredient that we could use so everything you're ingesting is working for you.
Resveratrol and quercetin are both polyphenols that commonly appear together in research settings and in nature.
Combining them provides a simple way to take both ingredients in one capsule whilst also not needing to use any fillers, binders or excipients.
We use high purity sources: our Trans Resveratrol is over 99 percent pure and Quercetin is over 95 percent.
Independent lab testing confirmed even higher figures at 100% Trans Resveratrol and 98% Quercetin.
We use 150 mg of ultra pure Trans Resveratrol per capsule to align with current FSA guidance on maximum levels for this ingredient in food supplements.
This ensures the product remains within UK regulatory limits while providing a clearly defined and compliant serving size.
The FSA’s current guidance sets a maximum level of 150 mg of trans resveratrol per day in food supplements, which is the amount contained in one capsule.
We therefore recommend taking one capsule per day to remain within UK regulatory limits.
Once per day at a time that fits your routine.
Take it with food.
