The Claim
Beta-alanine supplementation improves exercise capacity during high-intensity efforts by an average of 2.85% compared to placebo.
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.
Taking beta-alanine increases exercise capacity during high-intensity efforts by an average of 2.85% compared to taking a placebo.
See the scientific wording
Beta-alanine supplementation improves exercise capacity during high-intensity efforts by an average of 2.85% compared to placebo.
Beta-alanine enters muscle cells and combines with histidine to form carnosine. During intense exercise, muscles produce hydrogen ions that make the environment more acidic. Carnosine binds to these hydrogen ions, preventing the drop in pH. This keeps muscle proteins and enzymes working properly, so the muscles can keep contracting forcefully for longer before tiring.
What the research says
3 studiesTaking beta-alanine helped young runners last 6.5% longer before getting tired during intense exercise, compared to those who took a placebo. This means it really does help with high-intensity workouts.
Study: Effects of beta-alanine supplementation on Yo-Yo test performance: A meta-analysis.
Taking beta-alanine for 6 to 12 weeks helped athletes perform 2.85% better in a tough, high-intensity exercise test compared to those who took a placebo — exactly what the claim says.
Study: Effects of β-alanine supplementation on exercise performance: a meta-analysis
The study found that taking beta-alanine helped people exercise longer during intense efforts, and on average, they improved by exactly 2.85% — which is what the claim says.
