The Claim
Many believe that beta-alanine supplementation can universally enhance endurance across all types of physical activities, from short sprints to marathon running.
Origin
This myth likely stems from marketing claims and early studies that showed some performance benefits in specific contexts, leading to generalizations.
What Science Says
Research indicates that beta-alanine is most effective for high-intensity exercises lasting 1 to 4 minutes. A meta-analysis in the journal 'Amino Acids' found a moderate effect size for improving performance in this specific exercise duration. For longer endurance activities, the benefits are less clear, with some studies showing minimal impact.
Verdict
Partially True
