Caffeine before physical exercise helps increase strength, work capacity, and speed, as well as can delay the onset of fatigue. Caffeine consumption promotes lipolysis (fat burning), increases energy expenditure and can be useful in weight loss. It also increases the feeling of alertness, concentration and decreases the feeling of sleep. Caffeine Fire Nutrition® adapts to the needs of all types of athletes, students, vehicle drivers and any task that requires concentration. Instructions for use: Take 1 capsule a day.
