Beta-Alanine

Daily, split into smaller doses with meals to reduce tingling

Beta-alanine is a non-essential amino acid produced naturally in the liver and also found in meat and poultry. It serves as the rate-limiting precursor to carnosine, a dipeptide concentrated in skeletal muscle that plays a key role in buffering acid during intense physical effort. It has become one of the most widely studied ergogenic supplements for improving exercise performance in the 1-4 minute effort range.

Safety & Cautions

Side Effects

  • Paresthesia (tingling or itching sensation on the skin)
  • Skin flushing at higher single doses
  • Mild gastrointestinal discomfort in some individuals
Beta-alanine is generally well-tolerated at recommended doses. The tingling sensation (paresthesia) is harmless and dose-dependent — splitting doses or using sustained-release forms effectively eliminates it.
