Beta-Alanin — Uses, Dosage, Side Effects & Safety

Drug class: Amino Acid Supplement

Overview

Beta-Alanin is a naturally occurring amino acid that is commonly used as a dietary supplement to enhance athletic performance and exercise capacity. It is not used to treat diseases but is popular among athletes and fitness enthusiasts for its ability to help delay muscle fatigue during high-intensity exercise. Beta-Alanin works by increasing the concentration of carnosine in muscles. Carnosine acts as a buffer, helping to reduce the build-up of acid in muscles during exercise, which can improve endurance and reduce fatigue. Key points for patients: Beta-Alanin is generally considered safe when used as directed, but it may cause tingling sensations (paresthesia) in some people. It is important to follow dosing instructions and consult a healthcare professional before starting any new supplement, especially if you have underlying health conditions or take other medications.
