Scientists looked at the effect on exercise performance of beta-alanine alone or with sodium bicarbonate (baking soda) compared to placebo. They gave eight healthy men 4.8 to 6.4 grams per day of beta-alanine for 6 weeks. They also gave the men an average of 20 grams of sodium bicarbonate prior to the exercise testing. This amounts to 4 teaspoons. The exercise consisted of a repeated sprint ability (RSA) test and cycling capacity test.
