Caffeine

Caffeine is known for its beneficial effects on mental and physical functions. It has been shown to improve e.g. reaction speed, alertness and concentration. Caffeine also stimulates fat-burning during endurance activities and thereby helps to use fat stores in the body which results in a more efficient supply of energy. Caffeine is contained in many foodstuffs such as coffee tea or chocolate. One can of XL Energy Drink contains approximately the same amount of caffeine as a cup of coffee.

Taurine

Taurine is a conditionally essential amino acid which is naturally occurring in the human body. "Conditionally essential" means that in some situations or under certain conditions, as for example, in situations of high stress or physical exertion, increased amounts of taurine are eliminated from the body and cannot be replaced by the body in sufficient amounts. Taurine is involved in vital functions of the human body. Taurine acts as an antioxidant and has been shown to promote detoxification by binding together with harmful substances and thereby accelerating their excretion from the body.

Vitamins B group

B-group vitamins play an important role in energy metabolism, such as the build-up and break-down of carbohydrates, fat and protein. B vitamins are also shown to support mental and physical performance.
