Beta-alanine is a precursor of carnosine, a compound involved in buffering acidity inside the muscle. This makes it especially interesting for efforts where high intensity is sustained and fatigue accumulates.
Although it is often associated with short and repeated efforts, beta-alanine can also be relevant in endurance disciplines that include climbs, surges, final attacks or race segments above threshold.
This article reviews how beta-alanine works, what type of athlete may benefit, why loading strategy matters and what realistic expectations should be set before using it.
