Beta-Alanine Systematic Review Evidence
Beta-alanine systematic review evidence backs daily grams for weeks—not one scoop—to buffer acid in sustained hard efforts.
Beta-alanine systematic review evidence supports chronic three to six grams daily for two to four weeks to raise muscle carnosine, improving performance in roughly sixty-to-four-hundred-second efforts where acid limits output—repeat intervals, high-rep sets, and combat rounds. Single pre-workout doses do not build stores.
Tingling is benign. Reviews note modest effect sizes versus sleep and training quality.
Common questions
-
Do meta-analyses show beta-alanine helps every sport?
No—benefits cluster in acid-heavy repeat efforts. Pure aerobic base work and short phosphagen sprints gain less than glycolytic intervals and high-rep hypertrophy sets.
