Interest in resveratrol as a longevity compound surged after early studies linked it to red wine and longer lifespan in animals. It was exciting — a naturally occurring molecule that appeared to activate longevity pathways in the body. But over time, research uncovered a few limitations. Resveratrol is poorly absorbed, breaks down quickly in the body, and can interact with certain enzymes and medications.
A related compound, pterostilbene, has since gained attention for offering many of the same biological effects with significantly better bioavailability and stability. Structurally similar but more metabolically efficient, pterostilbene is now considered a more practical option for long-term use.
For these reasons, NOVOS Core includes pterostilbene — and not resveratrol — as part of its science-backed longevity formulation.
Key Takeaways
- Both resveratrol and pterostilbene activate longevity-related pathways such as SIRT1 and AMPK. But pterostilbene reaches higher and more consistent blood levels due to superior bioavailability.
- Resveratrol is rapidly broken down and eliminated, which limits its effectiveness unless taken at high doses.
- Pterostilbene’s greater metabolic stability allows it to work at lower, more practical doses for daily use.
- Research suggests pterostilbene may offer stronger anti-inflammatory and neuroprotective effects in preclinical models.
- Resveratrol can interfere with drug-metabolizing enzymes at high doses, while pterostilbene shows a more favorable safety profile.
- Long-term use, absorption, stability, and safety are just as important as antioxidant potential — which is why NOVOS Core includes pterostilbene instead of resveratrol.
What Are Pterostilbene and Resveratrol?
Pterostilbene and resveratrol are both members of the stilbene family — naturally occurring plant compounds with antioxidant and anti-inflammatory properties. They are known to influence some of the most studied biological pathways associated with aging.
Resveratrol is found in grapes, red wine, and peanuts. Pterostilbene is naturally present in blueberries and the bark of certain trees. Both compounds are thought to activate similar molecular pathways, including SIRT1, AMPK, and autophagy-related processes.
Although their molecular structures are nearly identical, small differences between the two make a big impact on how the body absorbs and uses them.
Key Differences Between Pterostilbene and Resveratrol
Both compounds are studied for their health-promoting properties. However, important differences in bioavailability, stability, and safety make pterostilbene the more reliable choice for daily supplementation.
Bioavailability
One of the most critical differences between pterostilbene and resveratrol is how well they are absorbed. Pterostilbene has an estimated bioavailability of around 80%, while resveratrol’s bioavailability is less than 20%, primarily due to rapid metabolism in the liver and intestines.
Therefore, a much higher dose of resveratrol would be needed to achieve the same systemic effects as a smaller dose of pterostilbene.
Metabolic Stability
Once inside the body, pterostilbene remains active much longer than resveratrol. The half-life of resveratrol in human plasma is approximately 14 minutes, while pterostilbene has a half-life closer to 105 minutes (source).
This greater stability allows pterostilbene to remain in circulation longer, interact with target tissues more consistently, and deliver its effects with lower, more practical doses.
Antioxidant & Anti-Inflammatory Effects
Both compounds act as antioxidants and have been shown to reduce inflammation and oxidative stress. However, research suggests that pterostilbene may exert stronger anti-inflammatory effects than resveratrol.
For example, one study found that while both pterostilbene and resveratrol reduce inflammation, pterostilbene consistently outperformed resveratrol in preclinical studies — particularly in models of liver inflammation, diabetes, and neurodegenerative disease.
Safety & Side Effects
While resveratrol is generally considered safe, studies show that it can inhibit multiple cytochrome P450 (CYP) enzymes, which are responsible for metabolizing many common medications. This finding raises concerns about potential drug interactions, particularly at high doses or with long-term use. In contrast, pterostilbene and its primary metabolites have shown minimal or negligible impact on these enzymes in in vitro studies, suggesting a more favorable safety profile for regular supplementation.

Longevity Research: What Does the Science Say?
Pterostilbene’s superior absorption and metabolic activity give it a practical edge over resveratrol for real-world use. But beyond pharmacokinetics, it also shows more consistent biological effects in preclinical longevity research.
A 2023 review of pterostilbene’s effects on brain aging and neurodegenerative diseases found it reduced inflammation, oxidative stress, and neuronal damage in multiple animal models — including models of Alzheimer’s, Parkinson’s, and epilepsy.
Separately, the Alzheimer’s Drug Discovery Foundation reviewed the compound’s neuroprotective potential. They highlighted its ability to cross the blood-brain barrier, activate SIRT1, and protect against cognitive decline and amyloid accumulation in rodents.
Direct evidence of lifespan extension in humans is still lacking. However, the cellular mechanisms supported by pterostilbene — including reduced neuroinflammation, improved mitochondrial function, and sirtuin activation — are all considered hallmarks of healthy aging and increased healthspan.
Why NOVOS Core Includes Pterostilbene (Not Resveratrol)
NOVOS Core was designed for daily, long-term use — which means every ingredient needs to be safe, effective, and biologically available. After reviewing the scientific literature, the NOVOS team chose pterostilbene over resveratrol for several reasons:
- Superior bioavailability and absorption
- Longer-lasting activity in the body
- Greater antioxidant and anti-inflammatory potential in preclinical models
- Fewer concerns about drug interactions or high-dose toxicity
Pterostilbene’s inclusion in NOVOS Core reflects the brand’s commitment to formulating with ingredients that not only show theoretical promise but also perform reliably in the body.
You Don’t Just Want Antioxidants — You Want Results
Resveratrol helped spark global interest in the science of slowing aging. But the more we learn, the more important it becomes to prioritize compounds that work in real biological conditions, not just in theory.
Pterostilbene brings together the best of both worlds: the same pathway activation as resveratrol, with far better performance in terms of absorption, stability, and safety. That’s why it’s part of the NOVOS Core longevity system.

For longevity purposes, pterostilbene is more bioavailable and more stable in the body, and it appears to have a better safety profile at typical supplement doses.
Why does NOVOS Core use pterostilbene?
Pterostilbene delivers longer-lasting activity and more reliable uptake than resveratrol, making it a more effective ingredient in daily longevity formulations.
Can I take both resveratrol and pterostilbene?
