Resveratrol, whose term in the official IUPAC nomenclature is: 5- [2E- (4-hydroxyphenyl) -ethenyl] benzen-1,3-diol is a non-flavonoid phenol with a brute or molecular formula: C14H12O3.
Resveratrol is a non-flavonoid phenol and phytoalexin that occurs naturally in numerous plants in response to attacks from pathogens such as bacteria or fungi.
This substance is found in some food sources the main of which are: grape skin, blueberries, raspberries, mulberry and peanuts.
Resveratrol is included in the list of the Ministry of Health “Other nutrients and other substances with a nutritional or physiological effect”. It carries out various biological activities although many are still to be validated from a scientific point of view.
Resveratrol has antioxidant and anti-inflammatory capabilities, is protective for blood vessels and is able to stimulate a series of processes involved in cell cycle regulation and DNA repair. Some studies also show that people who follow a diet rich in resveratrol would be less exposed to the risk of developing cardiovascular disease and cancer. In particular, its antioxidant capacity would contribute to the protection of cells from damage caused by free radicals and thanks to this property it would help fight against skin aging.
There are no claims approved by EFSA (the European Food Safety Authority) specific to resveratrol-based products.
The proposal for an indication that resveratrol, thanks to its antioxidant activity, protects cells from damage caused by free radicals and helps fight skin aging was rejected due to the lack of sufficient scientific evidence.
However, the research conducted so far has not revealed any serious side effects even in the case of large doses. However, it appears that resveratrol interferes with thinning drugs such as warfarin and non-steroidal anti-inflammatory drugs such as aspirin and ibuprofen, increasing the risk of bleeding.
It should be noted that a common resveratrol-based supplement on the market, the dosages are generally much lower than those that have proved useful in the experiment phase.
Resveratrol is commonly used as a dietary supplement, and studied in human disease models.
When taken orally, resveratrol is well absorbed by humans, but its bioavailability is relatively low because it is rapidly metabolized and eliminated.
