Research shows that beta alanine can improve both weight-lifting and endurance performance, so it could make all the difference if you’ve hit a plateau in the gym or can’t quite hit that 5k PB. For best results consume 2.4 to 4.8g 30 minutes before training. Science in Sport’s vegetarianfriendly option contains 1.6g per two tablets. Take two tablets, twice a day.
