Which supplement is often taken to improve endurance performance?

Beta-alanine is a supplement that is commonly associated with improving endurance performance. It serves as a precursor to carnosine, a dipeptide that acts as a buffer against acid build-up in muscles during high-intensity exercise. When athletes engage in endurance activities, such as long-distance running or cycling, the accumulation of hydrogen ions from lactic acid can lead to fatigue and decreased performance. By supplementing with beta-alanine, individuals can elevate their muscle carnosine levels, which can help delay the onset of muscle fatigue, allowing for improved exercise capacity and endurance.

This enhancement in exercise performance is particularly beneficial in high-intensity bursts within endurance events or during repeated high-intensity intervals. The ability to maintain performance over prolonged periods is crucial in tactical settings, making beta-alanine a favored choice among athletes looking to improve their stamina and endurance output.
