About this supplement

Beta-alanine is a non-essential, non-proteogenic amino acid that occurs naturally in the body. In its free form, it is the rate-limiting precursor for the synthesis of carnosine (β-alanyl-L-histidine) in skeletal muscle. Carnosine functions as an intracellular pH buffer, particularly during high-intensity exercise, by accepting hydrogen ions. Unlike alpha-amino acids, beta-alanine has the amino group attached to the β-carbon rather than the α-carbon. It is not incorporated into proteins. Supplementation increases intramuscular carnosine concentrations, which can enhance exercise performance by reducing muscular acidosis and fatigue. It is commonly used in sports nutrition.

How much to take

Typical amount
Typically 2-6 grams daily, often split into smaller doses of 0.8-1.6 grams every 3-4 hours to minimize side effects. A loading phase of 4-6 weeks is common.
