Beta-alanine is a non-essential amino acid. Unlike most amino acids, it is not used by your body to synthesise proteins. Instead, it is the building block of carnosine. Beta Alanine increases Carnosine concentration in the skeletal muscle, delaying muscle fatigue and letting you work out for longer.
Beta-alanine is commonly used for improving athletic performance and exercise capacity, building lean muscle mass, and improving physical functioning in the elderly. It is ideal for anyone doing prolonged endurance exercise.
The top food sources of beta-alanine are meat, poultry, and fish.
