There's a lot of science that goes into Hammer Nutrition's Race Day Boost, but it's the results that are most intriguing. By loading up on RDB for several days ahead of a big race, you can improve speed, stamina and power by up to eight percent, which could easily be the difference between finishing first or being off the podium.

Science is complicated, but all you really need to know is that Race Day Boost increases the production of ATP, which is the key building block of muscular energy. RDB also helps balance blood and muscle acidity and reduces lactic acid buildup, which will help you feel stronger longer, and provides short-term power as well as endurance.
