Pterostilbene is resveratrol's better-absorbed cousin — with a built-in solution for the one thing most supplement companies don't tell you about.

Resveratrol has been one of the most talked-about longevity molecules for over two decades. The "French Paradox" put it on the map. And the research is real — it does activate SIRT1, it does function as an antioxidant, and it does have potential cardiovascular and brain health benefits.
Here's the catch: your body barely absorbs it.
Standard resveratrol has roughly 20% oral bioavailability. If you take a 500mg capsule, only about 100mg actually makes it into your bloodstream. The rest is metabolised in your gut and liver before it can do anything useful. Scientists call this "first-pass metabolism," and it's resveratrol's biggest limitation.
This isn't controversial — it's well-documented in published pharmacokinetic studies. And it's the reason researchers started looking at resveratrol's molecular cousins. Specifically, pterostilbene.
Pterostilbene (pronounced "tero-STILL-bean") is a naturally occurring polyphenol found in blueberries, grapes, and almonds. Structurally, it's almost identical to resveratrol — same stilbene backbone, same mechanism of action. It activates the same SIRT1 pathway.
The difference is in the chemistry. Pterostilbene has two methyl groups where resveratrol has hydroxyl groups. That small structural change makes it roughly four times more bioavailable — significantly more survives digestion and reaches your cells intact.
That's not a minor improvement. It's the difference between a supplement that works mostly in theory and one that works mostly in practice.
Here's something you won't find on most pterostilbene product pages: taken on its own, pterostilbene has been observed to increase LDL cholesterol in some people.
Most supplement companies either don't know this, don't test for it, or bury it in fine print. We think that's the wrong approach. If you're taking a supplement for your health, you should know everything about it — including the parts that require a solution.
So we built the solution into the formula. Organic grape seed extract is a well-studied compound shown to support healthy LDL cholesterol levels. By combining 100mg of pterostilbene with 100mg of organic grape seed extract, we offset the one notable drawback before it becomes an issue.
You get the SIRT1 activation, the superior bioavailability, and the antioxidant protection — without the LDL concern. That's why the product is called Pterostilbene Extreme, not just Pterostilbene.
This is the kind of formulation decision that happens when a company reads the full research, not just the highlights.
The research is still evolving, but published findings point to several areas of potential benefit. Here's what scientists are studying — and what many customers report.
We didn't add twelve ingredients to make the label look impressive. Two active compounds, each at a purposeful dose, each with a specific job.
Other ingredients: Vegan pullulan capsule. That's it. No fillers, no flow agents, no magnesium stearate.

Take with or without food — pterostilbene absorbs well either way thanks to its lipophilic structure. Some prefer taking it with a meal containing healthy fats for further absorption support.
Pterostilbene's effects are primarily protective and cumulative. Unlike NMN, where many feel an energy difference within weeks, pterostilbene works more quietly — supporting cellular defence, SIRT1 activation, and antioxidant protection over time. Some report improved mood or mental clarity within the first few weeks, but the full benefits build with consistent use.
Both are stilbene polyphenols. Both activate SIRT1. Both function as antioxidants. But they're not the same.
| Pterostilbene | Resveratrol | |
|---|---|---|
| Bioavailability | ~80% oral absorption | ~20% oral absorption |
| Mechanism | SIRT1, antioxidant, MAO-B modulation | SIRT1, antioxidant, anti-inflammatory |
| Blood-brain barrier | Crosses readily | Partially |
| Half-life | ~105 minutes | ~14 minutes |
| Effective dose | 100–200mg daily | 250–500mg+ daily |
| LDL consideration | May increase without grape seed pairing | No LDL concern |
| Best for | Maximum absorption, brain-specific benefits | Broad polyphenol protection, cardiovascular |
| Research maturity | Growing rapidly, primarily preclinical | Extensive, including human trials |
Our recommendation: If absorption efficiency is your priority, pterostilbene makes more sense. If you want a more extensively studied compound with a broader research base, resveratrol may be the better starting point. Or do both — they complement each other through overlapping but distinct pathways.
| Product | What it is | Best for |
|---|---|---|
| Pterostilbene Extreme | 100mg pterostilbene + 100mg grape seed | Maximum absorption, SIRT1 focus, budget-friendly |
| Resveratrol + Quercetin | 500mg trans-resveratrol + 200mg quercetin | Classic polyphenol pairing, broad cardiovascular |
| Resveratrol PLUS | 1310mg: resveratrol + quercetin + fisetin + curcumin + piperine | Comprehensive polyphenol + senolytic stack |
At the most affordable price point in the Nutriop range, Pterostilbene Extreme is the most cost-effective way to add polyphenol protection to any existing supplement protocol.
Pterostilbene Extreme has a small but growing review base. Here's what we're hearing — plus what Nutriop customers report about our broader polyphenol range.
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 have been taking Nutriop Resveratrol for only 2 weeks now. I have had no side effects and seem to feel good. Order was easy and came on time. Will be ordering again.
Products are of high quality and delivered very quickly, in a day or two.
You can, and you should — blueberries are great. But you'd need to eat roughly 150 kilograms of blueberries to get the same amount of pterostilbene in one capsule. The concentration in food is simply too low for a meaningful supplemental dose. Think of Pterostilbene Extreme as a targeted top-up, not a replacement for a healthy diet.
You don't need both, but they do complement each other. Resveratrol has a broader research base and strong anti-inflammatory data. Pterostilbene has superior absorption and better blood-brain barrier penetration. Taking both covers more ground. If choosing one, pterostilbene delivers more active compound per milligram — which is why some people switch from resveratrol to pterostilbene entirely.
This is exactly why we formulated with grape seed extract. Published studies have observed that pterostilbene alone, at higher doses, may increase LDL cholesterol in some individuals. Our formula includes 100mg of organic grape seed extract specifically to counteract this effect. We built the solution into the product so you don't have to think about it.
That's the whole point. Because pterostilbene is roughly four times more bioavailable, you need a lower dose to achieve a similar level of active compound in your bloodstream. 100mg of pterostilbene with ~80% absorption delivers more usable compound than 500mg of resveratrol with ~20% absorption. Dose is not the same as efficacy.
Published safety data shows pterostilbene is well-tolerated at doses up to 250mg per day with a clean side-effect profile and no known significant drug interactions at supplemental doses. As with any supplement, consult your doctor if you're on medication — particularly blood thinners or statins, given the cholesterol considerations.
Two reasons. First, it's a two-ingredient formula — simpler formulation means lower production cost. Second, the 90-capsule bottle provides up to 90 days' supply at the standard dose, making the per-day cost very low. We priced it to be an easy add-on to any protocol, not a standalone premium product. It's the most accessible entry point in the Nutriop range.

💡 The maths: At this price for 90 capsules, Pterostilbene Extreme costs less per day than any other product in the Nutriop range. If you're looking for a low-commitment way to start a longevity protocol — or an affordable addition to your existing one — this is it.
