The benefits of Resveratrol – a powerful polyphenol
“Resveratrol does not act primarily as an antioxidant. It is far more interesting and powerful than that. Resveratrol turns on our body's genetic defences against diseases and aging itself.”
Dr. David Sinclair, A.O., Ph.D. Professor in the Department of Genetics and co-Director of the Paul F. Glenn Center for Biology of Aging Research at Harvard Medical School.

Resveratrol is part of a group of compounds called polyphenols. They’re thought to act like antioxidants, protecting the body against damage that can put you at higher risk for things like cancer and heart disease.
The molecule is found naturally in the skin of red grapes, but you can also find it in peanuts, red wine, berries, and other foods and berries.
Interest in the polyphenol really took off in 2003 when research by David Sinclair and his team at Harvard University reported that Resveratrol was able to increase the lifespan of yeast cells. The research published in Nature, was greeted by international media fanfare and launched a wave of research in the pursuit of an all-in-one longevity pill.
According to Prof. Sinclair’s findings, Resveratrol could activate a gene called sirtuin-1, which is also activated during calorie restriction in various species.
A lot of research has focused on the compound’s potential cardiovascular benefits as well.
Like many food supplements, all Resveratrol products are not created equal. “Pure Resveratrol” refers to the relative content of trans-resveratrol, the active ingredient and beneficial substance in resveratrol. Purification is the process of isolating trans-resveratrol from the rest of the plant and discarding the remaining impurities.
One clue to the purity of Resveratrol is its physical appearance. Pure Resveratrol powder (at least 98% purity) derived from Japanese knotweed, is white or off-white in colour, and (almost) doorless, while low-purity Resveratrol is light brown or darker, and has a strong, distinctive odour.
In general, the higher the purity, the lighter the colour. However, be careful, random lab testing has revealed that some companies add rice flour to a low-purity product in order to lighten it, which is pretty crazy if you ask us.
98+% pure trans-resveratrol (white or off-white in colour suggests purity. Make sure to ask for lab tests as some unscrupulous vendors may mix useless fillers to make it look white):
50% trans-resveratrol (brownish in colour - throw it away):
Because the FDA does not require purity values to be indicated on a product’s label, inferior products can be hard to spot.
Beware of bargain pricing and misleading descriptors such as “Extra Strength,” “Super Potency,” “High Purity,” and “Maximum Strength.” Many brands with these claims contain low-purity Resveratrol – between 20-50% – and while they may cost less per bottle, they require substantially higher doses to achieve the same effect.
With so many imposters on the market, what’s the best way to make an educated choice?
Pay attention to the “Supplement Facts” label, which should indicate both the “total product” content and the “trans-resveratrol” content.
By providing dual values, we can calculate the actual purity of the product in question. For example, a 50% pure product should be indicated on the label as “Resveratrol (Polygonum Cuspidatum Root): 500 mg yielding 250 mg Trans-resveratrol.” Or, “Standardized to 50% Trans-resveratrol.”
If you suspect that you have purchased a questionable product, ask the manufacturer for a COA (Certificate of Analysis) and/or a third-party lab testing certificate.
Our advice is never to buy Resveratrol that is less than 98% pure. Ignore all the hype branding especially empty words like “Super Potency” and “Extra Strength”. In fact, if you see these words and the powder is brownish in colour, you are best served by throwing the product in the rubbish bin as it will have no impact on your cells.
How to take Resveratrol
The thing about Resveratrol is that it is not soluble in water. It hates water so much so that if you pour it in a glass of water it will fall to the bottom like a cascade of brick powder.
We recommend you take your Resveratrol supplement with a meal so it gets dissolved along with the food and most crucially the fat content in your diet.
Ideally, we believe the best way to take resveratrol is with a tablespoon of extra virgin olive oil. Olive oil is an excellent source of oleic acid as well as modest amounts of Vitamins E and K.
In fact, oleic acid in of itself is another promising longevity molecule that is the subject of on-going scientific studies for its properties related to protection against heart disease, combating cancer, alleviating inflammation and activating sirtuins.
Resveratrol dissolves perfectly in olive oil given the high levels of natural monosaturated fats present and you also get the double benefit of a daily dose of extra virgin oleic acid – win-win!
