Beta-alanine is an amino acid that helps boost exercise performance.
Beta-alanine is a non-essential amino acid that's produced naturally in the body. It encourages the production of carnosine, a compound that plays a role in muscle endurance, which is why beta-alanine is known for its ability to boost exercise stamina and performance. When taken in doses over 2 grams, beta-alanine can cause tingling and itchiness. It doesn't happen to everyone, but if it happens to you, don't worry. It's harmless and should start to fade within 30 minutes.
