The REZ-V supplement Biotest sells contains only 600 mg resveratrol/serving. The above study indicates that a human of 180 pounds with an average metabolism requires close to 5,000 mg/day of resveratrol for an impact to occur on performance.
Thoughts?
I don’t recall anyone claiming they took REZ-V to improve endurance. From my understanding, that’s not what it’s designed to do.

While athletes should no doubt be excited about these Testosterone-increasing, estrogen-lowering effects of resveratrol, male and female Life Extension people have been all over this substance for other reasons.
An overwhelming amount of literature on resveratrol has demonstrated potent cardiovascular benefits, anti-aging effects, powerful anti-cancer effects, anti-arthritic, and neurological effects (e.g. potential benefits in treating Alzheimer’s Disease). Many of these benefits seem to stem from anti-oxidative and anti-inflammatory effects as well as gene modulation. (13-21)
What the Life Extension people are most excited about, though, is that resveratrol might actually extend lifespan.
Remember those calorie deprivation people that believed you could extend your lifespan considerably by just munching on a ridiculously low number of calories each day?
Well, one proposed mechanism by which calorie deprivation can make you live longer is that it activates a protein called SIRT1 (sirtuin 1). Activation of this protein inhibits PPAR-gamma activity and this causes your body to burn fat.
It’s not hard to imagine that having less fat might cause you to live longer, but remarkably, resveratrol activates this very same SIRT1 protein.
So even if you’re not concerned with extending your life at this point, resveratrol can cause your body to burn fat.
Maybe you’ve heard of the “French Paradox” (and no, it has nothing to do with why their star soccer player would head butt a guy in the finals of the World Cup)?
It’s the medical puzzle where certain populations (French and Greek) seem to experience a low incidence of coronary heart disease while eating a diet high in saturated fat. Epidemiologists have reasoned that it has to do with their daily consumption of red wine.
Well, many researchers have gone one step further and concluded that it was the resveratrol in the wine that was responsible for the French Paradox. (22-25)
This miracle substance has also been shown to have impressive anti-fungal and anti-viral properties, and may even protect the liver from excessive alcohol consumption or oxidative damage from taking too much acetaminophen. (26-39)
If all that wasn’t enough, there’s a good deal of data demonstrating that resveratrol is an extremely promising compound for the prevention and treatment of prostate cancer! (40-48)
So if taking Testosterone-boosting supplements has made you wary before because of possible prostate risks, resveratrol seems like the answer to your prayers.
Please read the above bold sections. These benefits rely on the activation SIRT1 protein, which was the same protein whose activation was observed in the experiment in my first post. Therefore, resveratrol activates the SIRT1 protein, yielding all these beneficial effects. However, if the resveratrol supplementation in the Biotest REZ-V is insufficient, and consequently the SIRT1 protein is not activated/not activated enough, then is REZ-V really effective?
