Slide3Mechanisms of Action
Active ingredient - 3,5,4'-trihydroxy-trans-stilbene Resveratrol is a polyphenol, a plant compound that has antioxidant properties, that has been known to help with heart disease, cancer, improve endurance, and reverse the effects of aging.
Resveratrol increases the action of SOD2, which reduces superoxide to hydrogen peroxide. Superoxide is a byproduct of the electron transport chain at complexes 1 and 3. It can cause free radical reactions, so it is important to keep these anions in check. By reducing superoxide to hydrogen peroxide, SOD2 plays the role of protecting the cell from mitochondrial dysfunction, changing the mitochondria’s permeability to certain substances, and defending the cell against apoptosis in certain diseases. These functions help by delaying the aging process, fighting against the proliferation of certain cancer cells, and aiding in the healing process when injuries occur.
The pathway
: Resveratrol has been shown to increase the action of SIRT1, which causes the migration of FOXO transcription factors to the nucleus. SOD2 is a target of FOXO3a, one of the FOXO transcription factors.Source: Robb EL, Page MM, Wiens BE, Stuart JA (March 2008).

Slide4Mechanisms of Action (cont’d)
Resveratrol has also been shown to interfere with all stages of carcinogenesis, initiation, promotion and progression. Studies have revealed that the mechanism by which resveratrol does this is by altering the transcription factor NF-KB, inhibition of a cytochrome P450 isozyme
, alterations in androgenic actions, and expression of cyclooxygenase enzymes.

Slide5Side Effects/Contraindications
Some studies have shown that resveratrol stimulates the growth of breast cancer cells because its chemical structure is similar to that of phytoestrogen.

Should not be taken by pregnant women because although it is known as an
anticarcinogenic
, it also displays carcinogenic properties which are not handled well by the fetus.
