Aside from the testimonials praising ginseng, scientists have found no evidence that it can boost energy levels or speed up recovery. When they ran the study, the people felt no different when they took it and exercised. I recommend saving your money rather than spending it on this training fad. Sodium bicarbonate can help your running, if you're a sprinter. Sodium bicarbonate acts as a buffer against lactic acid.
Lactic acid is produced more readily during anaerobic exercise, like sprinting.
However, in a longer distance, 5K or longer, research has shown that sodium bicarbonate has no effect, and as the distance increases some subjects experienced severe cramping. So take heed, unless you 're a sprinter, stay away from sodium bicarbonate. Another supplement boom has occurred with creatine. It is essential for the body to build muscles and it also acts as a buffer to prevent lactic acid. The theory is that if you load up on creatine you should have higher energy levels, faster times, and delayed fatigue.
