Beta Alanine is an amino acid and is the only naturally occurring beta-amino acid. Beta Alanines main effect is to increase the synthesis on carnosine. Carnosine has the ability to ward off fatigue, allowing you to train harder and for longer; it also assists in the reduction of lactic acids and muscle cramps throughout your workouts. Beta Alanine is also known for producing the ‘tingly’ sensation when consumed. This is very common, especially on first use. This will pass quite quickly.
