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 their lifespan spite of a high fat, high-calorie diet. Some of the changes included improved insulin sensitivity, increased number of mitochondria (the energy producing entity of the cell) and improved motor function (they moved better).
Methylated Resveratrol Formula
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 EF is a methylated resveratrol formula for increased bio-availability which also includes quercetin.

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).
Mice and people are however not the same, but there are also several studies on humans as well.
Resveratrol and quercetin have also demonstrated a dose-dependent inhibition of platelet aggregation (formation of blood clots) which may prove protective benefits against atherosclerosis (Pace-Asciak CR, et al, 2005).
Resveratrol has demonstrated antifungal activity against candida albicans (Jung HJ, et al, 2007).
Moreover, 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).
Benefits of Resveratrol
Resveratrol EF is a methylated resveratrol formula for increased bioavailability which also includes quercetin.
The following are some examples of research on the benefits of resveratrol in humans.
Flow-mediated dilatation of the brachial artery is a biomarker of endothelial function and cardiovascular health, and resveratrol has shown to increase flow-mediated dilatation up to 35% (Wong RH, et al. 2013 ,Wong RH, et al. 2013, Wong RH, et al. 2011).
Taking resveratrol supplements for a year significantly reduced hs-CRP and several other inflammatory markers (Tome-Carneiro J, et al. 2012).
Several metabolic markers were improved after 30 days of resveratrol supplementation, including reduced inflammation a reduced blood pressure (Timmers S, et al. 2011).
