The Claim
There is no clear dose-response relationship between the total amount of β-alanine supplemented (108–448g) and the magnitude of improvement in exercise capacity, indicating that benefits plateau at moderate doses.
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.
Increasing the total amount of β-alanine supplement from 108 to 448 grams does not lead to greater improvements in exercise capacity, and the benefits stop increasing at moderate doses.

β-alanine enters muscle cells and combines with histidine to make carnosine, which soaks up acid produced during intense exercise. This keeps the muscle less acidic, allowing it to keep contracting hard for longer without getting tired.

1 studyStudy: Effects of β-alanine supplementation on exercise performance: a meta-analysis
Taking more β-alanine doesn’t make you significantly more endurance-capable after a certain point — even low doses help, and extra doses don’t give you much more benefit.
