— a natural stimulant found in, among other things, coffee and tea. It accelerates metabolism and promotes the production of adrenaline and the release of stored fats. In addition, caffeine has a positive effect on the emotional state and performance, improves the effectiveness of training, and also reduces appetite. Moreover, this substance has practically no side effects; only at high doses or hypersensitivity to caffeine can characteristic signs of overexcitation (excessive sweating, nervousness, tremor, etc.) appear. Note that caffeine by itself does not provide a sufficiently powerful fat-burning effect, so it is often combined with other substances — in particular, green tea extract.
