What it is
Beta-alanine is a non-essential amino acid, meaning the body can produce it. It is a building block for carnosine, a compound found naturally in muscle and brain tissue. It can be produced synthetically for use in supplements and foods.
Why it's used
Beta-alanine is often added to sports nutrition products, such as energy drinks and protein powders. It is used to increase the body's carnosine levels, which may help improve athletic performance by buffering muscle acidity during exercise.
Health notes
Beta-alanine is generally recognized as safe (GRAS) by the FDA for use in certain food products. Some people may experience a harmless tingling sensation (paresthesia) when consuming beta-alanine, especially at higher doses. Regulatory bodies like EFSA have evaluated beta-alanine, and research is ongoing regarding its effects on athletic performance and other health aspects.
