The Claim
Twenty-eight days of beta-alanine supplementation at 3.2 grams per day significantly increases time to exhaustion by 23% and total work completed by 21% during high-intensity cycling at 120% VO2max in women aged 50 and older, compared to placebo, indicating a direct ergogenic effect on anaerobic endurance capacity in this population.
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 women aged 50 and older, taking 3.2 grams of beta-alanine daily for 28 days increases time to exhaustion by 23% and total work completed by 21% during high-intensity cycling at 120% VO2max compared to a placebo.

Beta-alanine builds up a substance in muscles that soaks up acid produced during intense exercise, letting muscles keep working harder for longer and clear out waste products faster after stopping.
What the research says
1 studyThis study found that women over 50 who took beta-alanine daily for four weeks could cycle longer and do more work before getting tired than those who took a placebo — exactly what the claim says.
