Resveratrol Sources

Resveratrol is a very popular compound that is making waves across all different areas of supplements that improve your overall health. This compound is naturally occurring and can be obtained from many different sources. The price of supplements can vary greatly due to how this compound is extracted and from what particular source. Let's take a look at some of the more popular sources of resveratrol so we can get a feel for them.

Red Wine and Grapes: The standard sources
For years, the most popular method of getting resveratrol was simply through drinking red wine. Red grapes have a very high concentration of this compound in their skins. As it's made into wine, most of it is pressed out and eventually ends up in the bottle on the shelf in your local supermarket. While drinking red wine is recommended by doctors on a moderate basis, you can also get concentrated supplements made from red grape skins. These supplements usually go by the name “red wine pill” and contain a fairly decent amount of resveratrol. The problem is, it takes a very long time for grapes to grow and they can only grow under specific conditions. This makes supplements using grapes a bit on the expensive side.
Japanese Knotweed: The cream of the crop

Japanese knotweed is, well, a weed that is very common in all types of different climates. This is by far the most potent source for resveratrol and also the most easy to harvest. This plant grows very fast and is extremely resistant to temperature changes. What this means for the consumer is that supplements made with this plant will be much cheaper while containing a higher concentration of resveratrol.
Other Sources

Resveratrol is found in small amounts in peanuts and various kinds of berries. Unfortunately, the process to extract it and the small amount of the compound in these ingredients just doesn't make it cost effective to manufacture. You can occasionally find some blueberry supplements that have resveratrol in them but it might not be enough to make any noticeable difference in your body's health.
