Creatine + arginine combo tested for quick power and focus

This study looked at whether taking creatine and L-arginine together, just once, can improve short bursts of exercise and mental reaction time in healthy, active men. Eighteen men tried each supplement alone, together, or a placebo in random order. They did sprint tests, jump tests, and a color-word reaction test one hour after taking the supplements. The goal was to see if the combination works better than either supplement alone.
