Resveratrol is found in the skin of grapes, but also in other various plants. It is known as an antioxidant and got a lot of attention when a study on mice showed that resveratrol increased the lifespan of these animals in spite of being fed a high fat, high calorie diet (Baur JA, et al. 2006). Resveratrol was found to stimulate SIRT-1, one of the longevity genes. Some of the other changes also include improved insulin sensitivity, increased number of mitochondria (the energy producing entity of the cell) and improved motor function (they moved better).
When tested, both resveratrol and quercetin were found to be potent anti-inflammatory agents (Donnelly LE, et al, 2004, Takada Y, et al, 2004).
Resveratrol and quercetin have also demonstrated a dose-dependent inhibition of platelet aggregation (formation of blood cloths) which may prove protective benefits against atherosclerosis (Pace-Asciak CR, et al, 2005).
Resveratrol has shown to inhibit cancer in human cell lines including breast cancer (Roncoroni L, et al, 2008, Tang FY, et al, 2008, Le Corre L, et al, 2005).
Resveratrol has demonstrated antifungal activity against candida albicans (Jung HJ, et al, 2007).

Resveratrol has been documented to be able to modulate enzyme systems involved in carcinogen activation and detoxification, which may be one mechanism by which resveratrol inhibits carcinogens (Chow HH, et al. 2011).
This is all very exciting, but the problem with resveratrol is that it has low bioavailability, metabolic stability because it is eliminated quickly (Walle T, et al, 2004). That problem is however solved by using methylated resveratrol. When the resveratrol is methylated it has shown to have approximately 5-to-8-fold higher permeability meaning absorption and also increased bioavailability (Wen X, Walle T. 2006, Walle T, 2007).
Resveratrol SC is a methylated resveratrol formula for increased bioavailability which also includes quercetin.
