Written by Aaron CuhaReviewed Sep 2026
Direct answer
Pterostilbene can be sold in Canada as a supplement or cosmetic ingredient, classified as "Sold as a supplement". That is not drug approval: Health Canada has not evaluated any health claim, and injectable or "research use only" versions fall outside supplement rules, so that label does not make human use lawful. On the evidence, 2 human studies are cited on its profile.

What Pterostilbene is
One randomised human trial, 80 adults with raised cholesterol. At 250 mg a day it lowered systolic blood pressure by 7.8 mmHg and raised LDL cholesterol by 17.1 mg/dL in the same people. No human trial has measured an ageing endpoint of any kind.
Pterostilbene is sold as the better resveratrol, and on one narrow measure that claim is defensible. In rats given equimolar oral doses, resveratrol was about 20 percent bioavailable and pterostilbene about 80 percent, because replacing two hydroxyl groups with methoxy groups slows the glucuronidation that destroys resveratrol on its first pass through the liver.
Mechanism: Structurally, resveratrol with two of its three hydroxyl groups replaced by methoxy groups. That change makes the molecule more lipophilic and a much poorer substrate for the phase 2 conjugation enzymes that clear resveratrol, which is the entire pharmacokinetic argument for it.
Regulatory history: Not an approved drug. Sold as a dietary supplement, frequently bundled with nicotinamide riboside or resveratrol in longevity formulations.
How Health Canada treats this kind of product
Authorises drugs for sale through a Notice of Compliance and Drug Identification Number. A compound that is not authorised for sale cannot lawfully be sold for human use, and personal importation of prescription drugs is limited.
The classification above is the The Longevity Archive reading of Health Canada, Health Products and Food Branch listings for Pterostilbene at the reviewed date, not a legal opinion. Rules change, and importing, prescribing and possessing a compound can each be treated differently. Check the regulator directly before acting on anything here.
