What buffering chemical/supplement will reduce lactic acid for runners but not generate $\ce{CO2}$? Sodium bicarbonate does so but causes gastric upset.




I don't think this question has an answer. First, [muscle soreness is not caused by lactic acid](http://lifehacker.com/5895140/10-stubborn-exercise-myths-that-wont-die-debunked-by-science). Second, distance runners run aerobically, meaning very little lactic acid would be generated by running in the first place. (Sprinters are the exception here.) Third, even if lactic acid buildup was a problem (which it isn't), both the cellular cytoplasm and human bloodstream are very well-buffered. The cytoplasm is primarily buffered by potassium glutamate and the circulation by bicarbonate (created from respiration). Production of "lactic acid" would really be production of lactate salts.
