Beta-alanine is a modified version of the amino acid alanine.
Beta-alanine has been shown to enhance muscular endurance. Many people report being able to perform one or two additional reps in the gym when training in sets of 8–15 repetitions. Beta-alanine supplementation can also improve moderate- to high-intensity cardiovascular exercise performance, like rowing or sprinting.
When beta-alanine is ingested, it turns into the molecule carnosine, which acts as an acid buffer in the body. Carnosine is stored in cells and released in response to drops in pH. Increased stores of carnosine can protect against diet-induced drops in pH (which might occur from ketone production in ketosis, for example), as well as offer protection from exercise-induced lactic acid production.
Large doses of beta-alanine may cause a tingling feeling called paresthesia. It is a harmless side effect.
How to Take
Standard daily dose: 2–5 g.
While beta-alanine is a popular ingredient in pre-workout stacks, supplementation is actually not timing-dependent.
Large doses of beta-alanine may result in a tingling feeling called paresthesia. This harmless side effect can be avoided by using a time-release formulation or by taking smaller doses (0.8–1 g) several times a day.
