Beta-alanine (The Tingles) is an amino acid naturally produced by the body and is also found in certain foods such as meat and poultry. It helps to increase levels of carnosine, another amino acid, in the muscles. Carnosine helps to reduce fatigue and increase endurance during high-intensity exercises, such as weightlifting or sprinting. Beta-alanine supplements are popular among athletes and bodybuilders to help improve exercise performance and muscle growth. They are generally safe and well-tolerated but can cause a harmless tingling sensation in the skin known as paresthesia.
