Creatine is believed to be the best selling sports supplement of all time. Creatine can be very beneficial to the athlete who does sprinting, weight lifting and any other quick burst activity. A creatine supplement is used so the athlete is able to do more reps, sets or weights before hitting the fatigue point. For a sprinter, the muscles should be able to fire more quickly and so improve times. For endurance athletes, it is much less clear what creatine can do. Creatine can come in powder, liquid (serum), pill, gum or effervescent powder form.

Creatine powder is by far the most popular form of creatine supplements. This is easily mixed with milk / water but does have a very gritty taste. Another major problem is that creatine powder is not the most effective at being absobed. The powder passes through the stomach and the acids in the stomach start to digest the creatine, which reduces the amount reaching the muscles.It is believed that as much as 40-50% of the creatine powder is lost before it ever reaches the muscles. Also, the powder tends to absorb more water which often leads to an upset stomach and possible dehydration. This problem is reduced by added water consumption..
