History of Resveratrol
Resveratrol is a natural substance found in plants such as grapes, berries, peanuts and oak trees. It was discovered in the mid-19th century when French scientists studying wine from the Bordeaux region of southern France identified a compound called resveratrol.
Repeated investigations led to the determination of the chemical structure of resveratrol and its classification as a phytoalexin. A phytoalexin is a plant substance that serves as a defense against bacteria and fungi and is mainly formed in stressful situations such as drought or cold.
Only since 1996 has resveratrol been considered by science as a potential health compound. Since then, thousands of studies have been published examining the potential benefits of resveratrol for fitness, endurance, immune function, memory, aging, cancer prevention, heart health, and fat burning.
In 2003, the study by David Sinclair and his research team at Harvard Medical School started the real resveratrol hype. They discovered that resveratrol activates enzymes in human cells that are responsible for longevity. Since then, resveratrol has been considered a potential life-prolonging agent.
How is resveratrol obtained?
Resveratrol is a natural polyphenol active ingredient that is mainly found in the skin of grapes. However, it is also found in other plants such as peanuts, maple leaves, blackberries and pomegranates.
Resveratrol is available as a dietary supplement in tablet and capsule form. It can also be made synthetically, but is not as effective as the natural sources.
The production of resveratrol is a complex process that takes place in several steps. First, grapes or other plants are pressed to release the resveratrol. This extract is then diluted with a solution of water and alcohol to separate the resveratrol from the other components of the plant.
In the next step, the resveratrol is concentrated by adsorption on an adsorbent. The concentrate can then be distilled to increase the concentration of resveratrol.
Finally, the resveratrol is crystallized to obtain a powder . The powder is then filled into tablets or capsules and marketed as a dietary supplement.
It is important to know that the production of resveratrol is a very complex and precise process to ensure the best possible quality. That's why you should make sure that the product you buy comes from a reliable source.
