Everything you’ve read about resveratrol, in the form and dose the research actually used.
Resveratrol is the polyphenol that put the cellular "longevity switch" on the map. Yet most supplements give you too little of it, in an inactive form your body barely absorbs. Nutriop delivers a full 500 mg clinical dose of 99% pure trans-resveratrol in every capsule, paired with 200 mg of quercetin, an antioxidant studied in the lab for slowing resveratrol's breakdown so more of it reaches your cells.
Why standard resveratrol capsules fail before they ever reach your bloodstream.
If you have ever taken an off-the-shelf resveratrol supplement and wondered whether it was working, there is a biological reason. Between published clinical trials and the average supplement aisle, three things go wrong:
01
The wrong molecular form
Resveratrol exists in two shapes: trans-resveratrol (biologically active) and cis-resveratrol (largely inactive). Many supplements use cheap grape-skin or red-wine extracts that contain only a tiny fraction of active trans-resveratrol, the rest is dead weight.
02
Token, underpowered doses
The human studies that made resveratrol famous used hundreds of milligrams of pure trans-resveratrol per day. Standard capsules often give you a token sprinkle padded out with cheap bulking agents.
03
Rapid breakdown in the gut and liver
Standalone resveratrol has a notorious bioavailability bottleneck. Your liver and digestive enzymes break most of it down on its first pass, clearing it before your cells can put it to work.
You can swallow a standard resveratrol capsule every morning and still never get what the research tested.
How this capsule fixes it
Full-strength trans-resveratrol, paired with the antioxidant that keeps it active.
Nutriop solves the form, dose, and breakdown problem in one purposeful formula. We start with 99% pure trans-resveratrol extracted from Japanese knotweed root, the exact active isomer used in clinical longevity research. Every capsule carries a full 500 mg dose: take one a day for proven daily support, or two a day to match the upper end of human research protocols.
Beside it sits 200 mg of quercetin dihydrate, a plant flavonoid sourced from Japanese pagoda tree buds and naturally found in apples and onions. In biochemical studies, quercetin has been shown to inhibit the specific enzymes that degrade resveratrol, helping more active trans-resveratrol circulate in your bloodstream while adding its own cardiovascular and antioxidant protection.

Why choose Nutriop
Engineered in a locked 5:2 ratio, with zero synthetic lubricants inside.
Plenty of brands sell resveratrol, and some even toss in a few milligrams of secondary ingredients just to dress up the label. We built Resveratrol + Quercetin around a strict 5:2 ratio, 500 mg of trans-resveratrol to 200 mg of quercetin, so every single capsule delivers a consistent, research-grade pairing rather than a guesswork blend.
Just as important is what we refuse to put in the bottle. To run factory encapsulation machines at higher speeds, most manufacturers coat their powders in chemical lubricants like magnesium stearate, silicon dioxide, and synthetic flow agents. We leave all of them out. Instead, we seal our active powders inside a clean vegan pullulan capsule, which naturally forms a superior oxygen barrier to protect light- and air-sensitive resveratrol.
Finally, because this formula contains two active ingredients, we test both of them separately at an independent ISO/IEC 17025-accredited laboratory and publish both certificates right on this page.
Cellular protection you build over time, not a jittery buzz that fades by noon.
Resveratrol is a foundational protective compound, not a stimulant. Its job is to support the cellular systems that keep your brain, blood vessels, bones, and metabolism resilient as the years pass:
Keeps your "longevity switch" in play
Resveratrol is widely studied for activating SIRT1, the sirtuin pathway your cells use for DNA repair and daily maintenance, the exact same cellular survival pathway switched on by fasting.
Supports healthy circulation and brain blood flow
In a human clinical trial, a single 500 mg dose of trans-resveratrol increased blood flow to the brain during demanding mental tasks. At daily doses starting from 30 mg, it has improved how effectively blood vessels relax.
Backs cognitive sharpness over the long run
Resveratrol crosses the blood-brain barrier. In a two-year clinical study at 150 mg per day, post-menopausal women showed healthier blood-vessel responsiveness in the brain alongside higher scores on memory tests.
Helps protect bone density in later life
In that same two-year clinical trial, taking 150 mg a day slowed age-related bone loss at both the lumbar spine and the hip.
Calms everyday cellular wear and tear
Both trans-resveratrol and quercetin are potent antioxidants studied for neutralising free radicals and supporting a balanced inflammatory response.
This formula is built for you if:
You have read the research on resveratrol and want the exact form and dose the clinical trials used
You already take NMN and want to pair your NAD+ fuel with a dedicated sirtuin activator
You prefer one clean, high-potency two-ingredient capsule over an underdosed ten-ingredient blend
You are building a long-term longevity routine and want the clearest, simplest place to start
One capsule a day to start. Two if you want the full clinical protocol.
1
1 capsule dailyCapsule daily
Standard Protocol
Take 1 capsule with breakfast (500 mg trans-resveratrol + 200 mg quercetin). A single bottle lasts two full months (60 days).
One bottle = 60 days
2
2 capsules dailyCapsules daily
Full Protocol
Take 1 capsule with breakfast and 1 capsule with dinner (1,000 mg trans-resveratrol + 400 mg quercetin) to match the upper range of published research and maintain steady levels throughout the day. A bottle lasts one month (30 days). Do not exceed 2 capsules per day.
One bottle = 30 days
How to maximise absorption: Take your capsule with a normal, balanced meal rather than a heavy, greasy one. In a human pharmacokinetic study, taking resveratrol alongside a heavy, high-fat breakfast roughly halved how much active resveratrol reached the bloodstream compared to a standard meal.
What to expect over your first 90 days
WEEKS 1–2
Warming up
Your body absorbs the polyphenols and begins supporting SIRT1 and vascular pathways at the cellular level. Because this is a protective compound rather than a stimulant, you won't feel a sudden caffeine-like jolt.
WEEKS 3–6
The first signals
Many customers notice steadier daytime energy, clearer mental focus, and smoother physical recovery, particularly when stacking with NMN.
WEEKS 6–12+
Compounding protection
The deepest benefits for blood vessels, brain health, bone maintenance, and cellular defense build quietly over months. Give it the full 90 days, our money-back guarantee covers every single one of them.
Storage: Store in a cool, dry place out of direct sunlight. No refrigeration needed.
Where it fits in the range
Three ways to take the sirtuin route. Here is how to choose.
Feature
This pageResveratrol + Quercetin
Resveratrol PLUS
Pterostilbene Extreme
What's in it
500 mg trans-resveratrol + 200 mg quercetin per capsule
Best for: Resveratrol's methylated cousin, roughly 4x more bioavailable at a lower milligram dose
Daily serving: 1 capsule · Price per bottle: € 34.95 (90 capsules) · Cost per day: € 0.39 a day
How to choose: Start here with Resveratrol + Quercetin if you want pure trans-resveratrol at the dose the clinical studies used, paired only with its absorption partner. Step up to Resveratrol PLUS when you want one formula to cover senolytic cell clearing as well, or add Pterostilbene Extreme if you want both stilbenes working together in your routine.
Resveratrol flips the sirtuin switch. These formulas supply the fuel.
Switching on your SIRT1 longevity genes is only half the job, those cellular repair proteins require NAD+ fuel to operate. Pair Resveratrol + Quercetin with these targeted Nutriop formulas to complete your stack:
The Fuel + Switch Pairing
Pure NMN
Sirtuins run on NAD+. NMN tops up your cellular fuel tank; resveratrol flips the activator switch. This is the classic longevity pairing researchers and customers return to again and again.
While resveratrol and quercetin help protect your cells from fresh oxidative damage, spermidine triggers autophagy, the cellular recycling process that clears out worn-out components already there.
Built for those who want sirtuin support alongside mitochondrial energy and antioxidant defense from CoQ10, Astaxanthin, and CA-AKG in one daily protocol.
Every batch tested twice, with both lab certificates published on this page.
Formulated in Switzerland, every batch of Resveratrol + Quercetin is independently tested by an ISO/IEC 17025-accredited laboratory (MS Bioanalytical) using HPLC-UV analysis. Because this is a two-ingredient formula, each active compound undergoes its own separate purity test before we approve the batch:

Feeling more alert and energetic. Back rowing and cycling again after 18 months of not doing anything. My concentration skills have improved which has helped with piano and French classes, and I just feel sharper and more awake.
Kay L. · Verified Buyer
★★★★★
By adding resveratrol to my supplements, this energy level has received a booster. Not only am I more awake and in the moment, even after a long day at work (and I get up at 5am), I'll be willing to do my workout at 10pm if necessary.
Jan, Germany · Verified Buyer (takes it with NMN)
★★★★★
I've been taking resveratrol from Nutriop for about three weeks now, and I have to say I'm very satisfied. While illnesses are spreading among my friends, I continue to feel full of strength and energy.
I‘ve been taking NMN vor over 2 years now, and I‘ve experienced a new level of energy after about 6 weeks. It‘s more like beeing fully awake the whole day. However, by adding Resveratrol to my supplements, this energy level has recieved a booster. Not only am I more awake and in the moment, Even after a long day at work (and I get up at 5am), I‘ll be willing to do my workout at 10pm if necessary.

Fair questions, straight answers
Straight answers to smart questions about resveratrol.
One capsule a day is our standard dose: it delivers 500 mg of trans-resveratrol (the exact dose used in the human brain blood-flow study) plus 200 mg of quercetin, making one bottle last two months. Two capsules a day give you 1,000 mg of trans-resveratrol, matching the upper end of published clinical studies, and a bottle lasts 30 days. Many people start with one capsule at breakfast and move up to two (one morning, one evening). Do not exceed two capsules a day.
A glass of red wine holds roughly 1 milligram of resveratrol, often less. You would need to drink around 500 glasses of red wine to match the trans-resveratrol in a single Nutriop capsule, and the alcohol would undo the benefits long before then. The "French Paradox" was an observation about overall diets, not a practical way to dose resveratrol.
They perform two different, complementary jobs. NMN raises NAD+, the cellular fuel your sirtuin "longevity genes" run on. Resveratrol is the compound studied for switching those sirtuins on. Taking both covers the fuel and the switch, the exact pairing longevity researchers keep coming back to, and the one Jan describes in his review above.
Three things you can verify right on the label:
The form: 99% pure trans-resveratrol from Japanese knotweed root, never a low-potency grape-skin extract.
The dose and pairing: A full 500 mg clinical dose of trans-resveratrol paired with 200 mg of quercetin in every capsule to help slow enzymatic breakdown.
The purity: A vegan pullulan capsule with zero fillers, flow agents, magnesium stearate, or silicon dioxide, backed by separate third-party lab certificates for both ingredients on this page.
Early media headlines overpromised, and several trials used tiny doses or unstandardised grape extracts that predictably underwhelmed. When you look at clinical studies using pure trans-resveratrol, the picture is much clearer: it activates the SIRT1 pathway in the lab, improves blood-vessel relaxation in humans at doses from 30 mg, increases cerebral blood flow during mental tasks at 500 mg, and, over two years at 150 mg a day, supported both memory test scores and spine and hip bone density in post-menopausal women.
Both ingredients are well tolerated at our recommended doses. Taking several grams of resveratrol a day can upset the stomach, which is why we cap our daily recommendation at two capsules (1,000 mg). Because resveratrol has a mild blood-thinning effect and quercetin can affect how the liver processes certain medicines, check with your doctor before use if you take anticoagulants or prescription medication, or if you are pregnant or nursing.
It varies by person, because much of what resveratrol does happens at the cellular level where you cannot directly feel it. That said, many customers report steadier energy or sharper focus within two to three weeks, while others take it specifically for long-term vascular, brain, and bone support. Give it a full 90 days, that is exactly what our money-back guarantee is designed for.
Yes, 100% vegan. The capsule shell is vegan pullulan rather than animal gelatin. The formula contains no soy, gluten, yeast, dairy, or synthetic additives, only trans-resveratrol, quercetin dihydrate, and the vegan capsule shell.

Wow que produto , nota se o seu refinamento entrga rapida
Excelente producto con resultados inmediatos, he probado otros productos de otra marca sin embargo recomiendo este en concreto por su rapidez en ver resultados.
I have used pure NMN power about 3 times 1st week and same 2nd week. I need try and take daily regularly than I can judge better. The product is nicely packaged also quick delivery and I certainly feel good after taking it. Will carry on.
Sehr empfehlenswert. Nmn am Morgen nüchtern mit Kollagenpulver mischen. Nach dem Frühstück Resveratrol, da es Fett braucht für die Aufnahme. Fühle mich wach und fit. Schlafe durch.
Questi prodotto è davvero valido la
Mia energia è cambiata radicalmente e adesso sto sistemando anche il peso
Lo uso da pochissimo ma sento i benefici su di me
He esperat uns dies per veure si funciona, i si, funciona! Noto més energia, però sobretot noto més capacitat mental, més rapidesa. Repetiré segur! Gràcies.
Ero un pò scettico ma curioso; devo dire che funziona!
Testato in montagna per lunghe escursioni e devo dire che aumenta i livelli di energia.
Grazie, Nutriop.
I’ve been taking the NMN supplement from Nutriop, and I feel a noticeable boost in energy and cognitive sharpness, especially when I take it in the morning on an empty stomach. While others around me have been feeling fatigued or falling ill, I’ve stayed healthy and energized. It’s been a great addition to my routine, and I highly recommend it for anyone looking to enhance their energy levels and mental clarity.
I’ve been taking resveratrol from Nutriop for about three weeks now, and I have to say I’m very satisfied. While illnesses are spreading among my friends, I continue to feel full of strength and energy. My immune system seems to be working exceptionally well, and I’ve stayed healthy throughout. I highly recommend it to anyone looking to boost their resilience and overall vitality.
Ik zal altijd deze product blijven gebruiken omdat ik merk het verschil de volgende dag met mij gewrichten en mij dagelijke activiteiten . Het zeker a wonder product .
Im coming up to 61 and have trained most of my life but my energy levels and body clock seemed to have died off. I found I needed a strict diet and to eat less to maintain weight so, I decided to try NMN and alter my diet and err slightly more to protein and it seems to have made a big difference. My training level is coming back and I find I can eat all I want and still look good..... and it's not just the diet as I have tried the diet alone but that simply did not work, the NMN definitely makes a difference.
