it acts as a buffer of lactic acid which will improve your performance down sides are it makes you ill (vomiting and the shits) one of my lecturers last year took part in a study on the effects of it on sporting performance and knocked some considerable time off a 10k hill run.Spend a few days in bed/on the toilet after wards and said it was horrible to take.
