The Claim
Twenty-eight days of beta-alanine supplementation reduces blood lactate concentration by 24% during passive recovery 20 minutes after high-intensity cycling at 120% VO2max in women aged 50 and older, indicating enhanced lactate clearance capacity as a physiological mechanism underlying improved endurance performance.
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 beta-alanine for 28 days lowers blood lactate levels by 24% during passive recovery after intense cycling at 120% of VO2max, reflecting increased capacity to clear lactate from the blood.

Beta-alanine builds up a substance in muscles that soaks up acid produced during intense exercise. This keeps the muscle environment less acidic, allowing the body to remove lactate from the blood faster after exercise stops.
What the research says
1 studyAfter taking beta-alanine for four weeks, older women cleared lactate from their blood 24% faster after intense cycling than those who didn’t take it, which may help them recover better and ride longer.
