Subject: Effects of β-alanine supplementation on exercise performance

What does this rating mean?
A solid systematic review with caveats, or consistent indications with a limited scope.
Findings
Beta-alanine supplementation can slightly improve performance in efforts lasting 1 to 4 minutes, particularly during repeated high-intensity exercise; effects are larger with more than four weeks of supplementation.
Size of the research
Fifteen studies with 360 participants in total: 174 took beta-alanine and 186 a placebo.
What to keep in mind
The authors call this a preliminary analysis. There was no benefit for efforts shorter than 60 seconds. Tests of exercise performance also showed no improvement.
Practical conclusion for REZA
Beta-alanine is a niche supplement for specific short anaerobic contexts, not a generally recommended addition for every workout.
