lactic acid

[nolinenowait]

are there any supplements that decrease lactic acid build up

Gakic helps with muscle fatigue. That might help.

Also, Creatine supplements basically add more creatine into your blood so when your muscles run out of creatine, the blood will replenish the muscle with more and in turn, less lactic acid will build up.

Try stretching post-workout.
