Verdict
3.2 g a dayas the label directs · studies use 3.2–6.4 g/day of beta-alanine
Effective doseTaken as the label directs (2 servings a day, 1.6 g each), it gives 3.2 g a day; studies use 3.2–6.4 g/day.
One tablet gives 800 mg, so reaching the low end of what studies use (3.2 g) takes 4 tablets a day; it ranks 12th of 19 beta-alanine supplements here by dose.
4 tablets a day reach 3.2 g.
