When some plants get injured or attacked by bacteria, they produce an amazing substance to help repair the damage. Resveratrol is one such compound released by plant tissues in response to damage or injury.  Extensively studied for its numerous health benefits, resveratrol is a powerful antioxidant.

Natural sources of resveratrol include grapes, berries such as cranberries, mulberries, blueberries, bilberries, cocoa, peanuts and pine trees. Although red wine made from grapes is widely cited as the best source of resveratrol, there is actually very little of the antioxidant in wine. Almost all of resveratrol is concentrated in the skin of grapes and berries. With fermentation and further processing of grapes for wine production, there is considerable loss of resveratrol.  White and rose wines do not contain any resveratrol.

 

Health benefits of resveratrol

Being a powerful antioxidant, resveratrol has been found to have health benefits in clinical trials involving animals.

  • Inhibition of cancer cells: Free radical damage is believed to be the cause behind diseases such as cancer. Free radicals are generated during normal digestion process in the body, but could also enter the body from environmental pollutants, smoking, heavy metals and mental stress.  The radicals being very unstable disturb other healthy cells leading to a chain of destruction. Resveratrol helps make these radicals stable and neutralizes them.
  • Cardiovascular health: Some clinical trials have shown that resveratrol can help lower inflammation that contributes to heart disease.
  • Control of Alzheimer’s: Recent research has shown beneficial effects of resveratrol supplementation in controlling the progress of Alzheimer’s.
  • Exercise tolerance: Many athletes and exercise enthusiasts find resveratrol boosts endurance.

 

Choosing the resveratrol supplement:

The dosage: When choosing resveratrol supplements, it is important to note the dosage. Most studies and clinical trials have used a high dosage of up to 1000 milligrams of resveratrol.  While extensive safety studies have not been done, according to the University of Pittsburgh Medical Center, 500 milligrams is a safe intake.

The source: Choose a supplement that is made from the skins of grapes or berries. All of the resveratrol is found only in the skin of these fruits.

The form: There are two forms of resveratrol that relate to the different structural arrangements of the compound, called trans and cis. Trans-resveratrol has been extensively studied and is believed to be more biologically available than cis form.

Concentration:  The supplement should contain 98% or more of resveratrol that is made from whole grape skin.

Check also for additives, chemicals and sugar which can do more harm than good while selecting the resveratrol supplement.
