Resveratrol (molecular formula: C14H12O3, CAS number: 501-36-0, also known as 3,5,4′-trihydroxy-trans-stilbene) is a substance naturally found in common foods, such as wine, grapes and several types of berries in tiny amounts. 

We provide high purity, pharmaceutical grade, independently verified micronized trans-resveratrol, for sale in the UK with delivery worldwide, at fair and reasonable prices.

Resveratrol is naturally found co-existing in two chemical structures; trans-resveratrol and cis-resveratrol. Trans-resveratrol is the molecule that is most stable and bioavailable, and is the version extensively studied and known to be beneficial. Cis-resveratrol is unstable and worthless as a nutritional supplement.

Reducing the particle size of trans-resveratrol (known as micronizing), increases the surface area, and has shown to substantially increase the amount of trans-resveratrol to make it into the blood; roughly doubling peak plasma levels.

This is why PlantPills resveratrol is trans-resveratrol, and is micronized. In fact, PlantPills trans-resveratrol is micronized to have an average particle size of less than 1.5 microns (less than 0.0015mm), compared to a size of at least 50 micron (0.05mm) for standard resveratrol.

Nobody should consider taking any resveratrol supplement if the retailer can’t provide test results from a third party laboratory.

The test results should be from a reputable laboratory that isn’t associated with the manufacturer or the retailer, and should confirm that the product is at least 99% pure trans-resveratrol, and doesn’t contain any dangerous levels of heavy metals or micro-organisms.

Without third party testing, it’s completely unknown whether the product is what it claims to be, and whether it’s safe for human consumption. Unfortunately the market is rife with fake and low-grade resveratrol due to the high price.

Every batch of PlantPills micronized trans-resveratrol powder is independently verified to have a purity of at least 99%, with no dangerous levels of heavy metals or micro-organisms. The certifications for the current batch are viewable below. The current batch of our trans-resveratrol powder has a purity of 99.7%. 

We have other pack sizes available: 5 grams, 10 grams, 25 grams, 50 grams, 100 grams, 250 grams, 500 grams, 1 kilogram and 2 kilograms.
