Caffeine contributes to an increase in endurance performance and endurance capacity and to a reduction in the rated perceived exertion during exercise. The beneficial effect is obtained with 3 mg of caffeine per kg of body weight one hour before exercise; one serving provides 200 mg, which corresponds to 3 mg/kg for a person weighing about 67 kg. Not recommended for children or pregnant women.
Optimum Nutrition recommends mixing 21 g (about 3 level scoops) with 400 ml of cold water and taking it 15 to 30 minutes before training. Recommended intake: 1 serving per day, with no other sources of caffeine.
It is a known effect of beta-alanine (3.2 g per serving): a temporary, harmless tingling sensation on the skin, called paraesthesia, which fades after a short time.
