Reliable and relatively consistent scientific data showing a substantial health benefit. Contradictory, insufficient, or preliminary
studies suggesting a health benefit or minimal health benefit. For an herb, supported by traditional use but
minimal or no scientific evidence. For a supplement, little scientific support and/or minimal
health benefit. | |
Since it is not an essential nutrient, resveratrol is not associated with a deficiency state.
An 8-ounce glass of red wine provides approximately 640 mcg of resveratrol, while a handful of peanuts provides about 73 mcg of resveratrol. Resveratrol supplements (often found in combination with grape extracts or other antioxidants) are generally taken in the amount of 200–600 mcg per day. This is far less than the amount used in animal studies to prevent cancer: equivalent to more than 500 mg (500,000 mcg) per day for an average-sized human. Therefore, one should not assume that the small amounts found in supplements or food would necessarily be protective. The optimal level of intake is not known.
While a moderate intake of red wine may protect against heart disease, the optimal amount required to produce this effect is still unknown. Due to the risks involved with drinking alcohol, drinking red wine cannot be recommended as a means of preventing heart disease until more information is known.
No side effects have been reported with the use of resveratrol.
At the time of writing, there were no well-known drug interactions with resveratrol.
