Pterostilbene
Best-in-class: Pterostilbene
A blueberry-derived cousin of resveratrol that is far more bioavailable and longer-lasting — a sirtuin-activating longevity and metabolic compound (paired with NR in ResveraCel/Basis).
How Pterostilbene actually works
A dimethylated analogue of resveratrol. The two methoxy groups make it considerably more lipophilic and resistant to glucuronidation, so oral bioavailability and half-life are both substantially higher — this is the same mechanism with a fixed pharmacokinetic profile.
Pterostilbene quick facts

✅ Clinically validated
- Small RCTs show effects on cholesterol and blood pressure; strong antioxidant and metabolic activity in studies.
- Better absorbed and more stable than resveratrol.
📊 Correlative data
- Polyphenol intake is broadly associated with cardiometabolic benefit.
🧪 Theoretical / extrapolated benefits
- Sirtuin/longevity promise is strong in animals; human healthspan outcomes remain unproven.
These tiers tell you how much human evidence exists — not how well something works. This is the research space, and most of what’s in here is new rather than disproven. Something sitting at “theoretical” usually means nobody has funded the trial, not that the trial was run and failed.
The trap runs the other way too: something can be clinically validated and still do very little for you specifically. A statistically significant result in a study population is not a promise about your body.
- ✅ Clinically validated — human randomised trials or meta-analyses support it. The strongest footing available.
- 📊 Correlative — observational or epidemiological data. Suggestive, and genuinely useful for direction, but it cannot establish cause.
- 🧪 Theoretical / mechanistic — the mechanism is understood and often demonstrated in cells or animals, and the human trial doesn’t exist yet. Unproven is not the same as ineffective. Plenty of what’s standard practice today sat here five years ago.
✗ is a safety flag, not a grade. Where you see it, the concern is harm — not a disappointing trial. A compound tested for one purpose and found not to help there can still be worth studying somewhere else, so a negative result never gets rendered as a cross. It sits alongside the tier, because something can be both well-studied and genuinely risky.
My job is to tell you which one you’re looking at, and let you make the call. Grading something low isn’t me dismissing it — it’s me refusing to oversell it. This is the research space, and being able to reason forward from a mechanism matters as much as waiting for the trial.
Inherits both the mechanism and the uncertainty, with better delivery. One finding worth knowing before adding it to a longevity stack: at higher doses it raised LDL cholesterol in a human trial, which is an awkward result for a compound taken for cardiovascular ageing. Frequently combined with NAD+ precursors on the sirtuin rationale, which rests on the contested part of the story.
Pterostilbene — safety & side effects
- Well tolerated; GI upset at higher doses.
- Raises LDL cholesterol — this was a reproducible finding in the human trial and is the distinctive thing to know about it versus resveratrol.
- Antiplatelet activity and CYP inhibition, as with resveratrol. Additive bleeding risk with anticoagulants and antiplatelets — warfarin, apixaban, rivaroxaban, clopidogrel, and aspirin at any dose. The interaction is pharmacodynamic rather than metabolic, so it does not show up as a changed drug level; it shows up as bruising, nosebleeds or a raised INR.
- Better bioavailability than resveratrol, which means the effects and the interactions both arrive more reliably.
