Taking beta-alanine supplements does not change anaerobic performance in female athletes.

See the scientific wording

Beta-alanine supplementation has no significant effect on anaerobic performance in female athletes.

Why this might work

Beta-alanine enters muscle cells and combines with another amino acid to form carnosine, which soaks up acid produced during intense exercise. This reduces the amount of acid that leaks into the blood, lowering lactate levels. However, the main reason muscles tire during short bursts of activity is not from acid buildup, but from depletion of a fuel molecule called phosphocreatine and slow recovery of energy between efforts. Since carnosine does not help restore this fuel or speed up energy production, performance does not improve even though acid levels drop.

What the research says

3 studies

  1. Study: No ergogeniceffect of β-alanine on repeated sprint ability: a systematic review and multilevel meta-analysis of randomized controlled trials

    Scientists looked at 17 studies where athletes took beta-alanine supplements and then did short, intense sprints. The supplements didn’t make them faster, stronger, or less tired during the sprints — so they don’t seem to help anaerobic performance in female athletes.

  2. Study: Effect of Beta-Alanine Supplementation on Exercise-Induced Cell Damage and Lactate Accumulation in Female Basketball Players: A Randomized, Double-Blind Study

    The study found that taking beta-alanine didn't make female basketball players jump higher, run faster, or shoot better — even though their performance improved overall, it improved just as much for those who took a sugar pill. So the supplement didn't help.

  3. Study: Effects of Acute Beta-Alanine Supplementation on Anaerobic Performance in Trained Female Cyclists.

    The study gave female cyclists a beta-alanine pill and found they didn’t ride any harder or faster than when they took a sugar pill, even though they felt a little less tired. So, the supplement didn’t actually improve their performance.
