Effective antioxidant, and this is the basis of youth, as everyone knows. A big plus of this product is practically complete absence of caffeine (only 4 mg, in a cup of coffee - 100 mg). That is, you can take it at any time of the day. On the packaging of the postscript - must be taken with food. And it's not just that - somehow took 15 minutes after eating - and there were unpleasant sensations in the stomach. Can be used as a fat-burning component (naturally, in conjunction with training)). Also used for the prevention of oncology. I took for prophylaxis, because among relatives there is oncology. Obligatory to receive smokers. *********** If my feedback was helpful, please click YES!)
