More recently, research indicates its potential ergogenic value to mental focus and/or physical performance, but it is important that you also understand what sports drinks are. Sports drinks are a segment within the beverage industry and are marketed to consumers with the main function of promoting hydration, replacing electrolytes and sustaining aerobic resistance capacity. Usually provide small amount of carbohydrates (e.g., 6-8 grams/100 ml) and electrolytes (sodium, potassium, calcium, magnesium).

On the other hand, it typically contains higher amounts of carbohydrates along with nutrients purported to increase attention perception and/or mental alertness. In the positioning of the newly published ISSN, it was approached with details about both, which are commonly consumed by athletes and the general population.


There are many compounds present in energy drinks, the main being Caffeine. This is a stimulant, which increases metabolic rate and lipolysis, in addition to alertness, mood, cognitive function. Guarana is another natural source of caffeine, with effects similar to the effects of caffeine.

With green tea, you can get large amounts of polyphenols and catechin (e.g., epigallocatechin gallate or EGCG), acts as a potent antioxidant. Another recently studied compound is Yohimbine Alkaloid, with stimulating and aphrodisiac properties, similar to the effects of caffeine.
