Synopsis

Source of validity: Scientific
Rating (out of 5): 4

Alpha-Alanine (often referred to as beta-alanine in the context of exercise aids; alpha-alanine is a structural isomer and is not commonly used in supplements), is an amino acid found in proteins, but it is beta-alanine that is widely recognized for its athletic performance benefits. Beta-alanine supplementation increases muscle carnosine levels, which helps buffer acid in muscles, thereby reducing fatigue and improving exercise performance, particularly during high-intensity activities. Multiple high-quality, peer-reviewed studies and meta-analyses have demonstrated that beta-alanine supplementation can enhance performance in activities lasting 1-4 minutes, such as sprinting or rowing. The International Society of Sports Nutrition (ISSN) considers beta-alanine to be an effective ergogenic aid for such uses.

However, alpha-alanine itself is not specifically supported by the literature for use as an exercise aid, and most references to “alanine” in the context of athletic supplementation actually pertain to beta-alanine. If the ingredient in question is truly alpha-alanine, there is little to no direct evidence for its effectiveness in exercise performance. The score and justification above pertain to the widespread scientific evidence for beta-alanine, as alpha-alanine is not recognized for this use.

For athletic and exercise support, beta-alanine is among the most scientifically validated amino acid supplements, but alpha-alanine should not be conflated with it.
