The Claim
Four weeks of daily beta-alanine supplementation at 6.4 g/day in highly-trained male and female judo athletes increases the total number of throws performed during a standardized judo-specific performance test by approximately 15-20%, without altering blood pH or bicarbonate responses to exercise, with enhanced performance associated with increased lactate production and tolerance rather than acidosis buffering.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In highly-trained judo athletes, taking 6.4 grams of beta-alanine daily for four weeks increases the total number of throws performed in a standardized test by 15-20%, without changing blood pH or bicarbonate levels during exercise, and the performance improvement is linked to higher lactate production and tolerance.
See the scientific wording
Four weeks of daily beta-alanine supplementation (6.4 g/day) in highly-trained male and female judo athletes likely increases the total number of throws performed during a standardized judo-specific performance test by approximately 15-20%, without altering blood pH or bicarbonate responses to exercise, suggesting enhanced performance may be linked to increased lactate production and tolerance rather than acidosis buffering.
Beta-alanine builds up a substance in muscles that soaks up acid produced when the body breaks down sugar for energy. This lets muscles keep working hard longer without slowing down, even though more acid and lactate build up. The muscles don't get more resistant to burn — they just handle more acid and keep producing power.
What the research says
1 studyStudy: Beta-alanine supplementation enhances judo-related performance in highly-trained athletes.
Taking beta-alanine for four weeks helped elite judo athletes do 15–20% more throws in a simulated match, not because it reduced muscle burn, but because their muscles got better at handling lactic acid buildup.
