The originality of Powergrape®, the result of research and the expertise of Naturex lie in its special mechanism of action: scientific studies have revealed its exceptional antioxidant capacity linked to increase in oxygenation of the muscles, and to improvement in performance in people taking the supplement.
Powergrape® is a plant extract obtained from grapes produced on Bordeaux vines (Vitis vinifera L.). With its special composition, Powergrape® has been perfected so as to take advantage of its tonic and protective properties in relation to oxidative stress, which have been demonstrated in several clinical studies.
Effect on tone and vitality
The tonic activity of Powergrape® has been demonstrated in a clinical study undertaken in top level sportsmen during a competition.
The activity of Powergrape® on the performance and recovery of subjects studied was evaluated using a scientifically validated test of physical effort: the OPTOJUMP® test (to learn more).
It can be seen that tone was regained by sportsmen who took the supplement Powergrape®, compared with those who took a placebo. These properties of Powergrape® are to a large extent the result of its activity in protecting against oxidative stress (to learn more) and the risk of muscle damage (to learn more) – as well as its ability to improve the oxygenation of the cells of our organism.
Protecting the muscles
Powergrape® is capable of protecting the muscles from the risk of being torn and from cramp.
The protective action of Powergrape® on muscle cells has been measured with the plasma marker for muscle damage and cramp, creatine phosphokinase (CPK). The lower the concentrations of this marker, the lower the risk of muscle damage and cramp and therefore the greater the protective activity of Powergrape®.
This result explains part of the results obtained for performance and recovery. The production of energy by muscles actually generates increased oxidative stress that could be toxic for muscle cells.
