Why supplements are better than Resveratrol from natural sources

Date

Resveratrol is a natural stilbenoid with multiple health-enhancing effects.
It is produced by certain plants, such as grapes, pistachios, apples, raspberries, blueberries, plums, peanuts and their by-products (e.g. wine).
Resveratrol can be isolated and purified from these biological sources or synthesized in several steps with an overall high yield.[1]

Which wine varieties have the highest Resveratrol content

Eating black or pink grapes or drinking grapefruit juice could be one way to get Resveratrol directly.
The problem is that the amount of Resveratrol in these natural sources is very low and therefore insufficient.
[2] Resveratrol is most commonly associated with black grapes.
Wine varietals such as Malbec, Petite Sirah, St. Laurent and Pinot Noir have the highest resveratrol content.
Malbec grapes have the thickest skins and therefore the highest resveratrol content.
Red wines have a resveratrol content of between 0.03 and 1.07 milligrams per 150-mg glass, while white wines have a lower resveratrol content of between 0.01 and 0.27 milligrams per 150-mg glass.
Grape juice contains 0.017 – 1.30 milligrams per 150-milligram glass.[3]

Why we can’t get the same benefits directly from nature

According to studies, a daily intake of 1 gram of resveratrol is optimal for maximum health effects.
To benefit from this amount, however, you would need to consume, for example, 795 kilograms of black grapes, or 2584 kilograms of white grapes, or 2500 kilograms of apples, or 2857 kilograms of dark chocolate, or 10,000 kilograms of milk, or 52.6 kilograms of tomato peel.
[4] But is it possible to combine the useful with the pleasurable?
Namely, getting the desired dose of resveratrol from wine, especially red wine?

The French paradox and why resveratrol tablets are the optimal solution

There is a so-called ‘French paradox’, which goes like this: why the French, who eat a lot of fat, especially cheese, have a very low incidence of coronary heart disease.
[5] One possible explanation is that they traditionally drink a glass of red wine before a meal, thus ingesting a large amount of resveratrol, which reduces cholesterol and the incidence of vascular disease?
The problem is that the resveratrol in wine has declined in recent decades and that bottling it in barrels also lowers the concentration.
A study in Australia measured Resveratrol concentrations in 16 varieties of wine, aged between one and six years, both immediately after harvest and 16 months afterwards, and found that they had fallen dramatically.
[6] This is why resveratrol tablets are the optimal solution.
Each tablet contains 500 milligrams of resveratrol, so from two tablets you can easily get the optimal daily dose you need.
