Resveratrol (RES) (3,5,4′-trihydroxystilbene) is a stilbenol derived from stilbene, a natural product. RES is found in varying amounts in grapes, various berries, plums, peanuts (and pines).
Oral resveratrol is rapidly metabolized via sulfate conjugation by the intestine/liver. The methyl capping of all free hydroxyl groups (as in Pterostilbene) results in dramatically higher hepatic metabolic stability, intestinal absorption and membrane transport compared to unmethylated RES.
Quercitin, pterostilbene and resveratrol are synergistic antioxidants, with quercitin seemingly aiding in the absorption of resveratrol.*
Stilbenols are polyphenolic compounds that have cell-protecting properties. For RES, this action has mostly been linked to growth and death regulatory pathways. Research published in 2008 also demonstrated RES’s contribution to the maintenance of genome stability. Pterostilbene and quercetin, structurally-related and naturally-occurring, small polyphenols, show longer half-life in vivo than unmethylated resveratrol and have been shown to work synergistically to protect cellular health.*
As exciting as its role in chemoprotection, is resveratrol’s ability to produce changes associated with longevity. These include increased insulin sensitivity, reduced IGF-1, increased AMP-activated protein kinase and peroxisome proliferator-activated receptor-gamma coactivator 1 alpha activity, increased mitochondrial number and improved motor function. RES opposed the effects of the high calorie diet in 144 of 153 significantly altered gene pathways. RES activates sirtuins including SIR2, a special longevity cellular and SIRT1 that helps protect nerve cells.*
Resveratrol’s numerous anti-inflammatory properties may explain why it has so many far-reaching health benefits. It inhibits synthesis and release of pro-inflammatory mediators, modifies eicosanoid synthesis, and inhibits activated immune cells. By inhibiting either NF-(kappa)B or the activator
protein-1 (AP-1), resveratrol also appears to inhibit inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2). Specific human dosing to support a healthy inflammatory response has not yet been established.*
