How well does the Creatine Supplement for weightlifting work anyway?
Muscle contractions require energy input in the form of ATP, a giant molecule found all over your body that stores chemical energy. The energy is released when ATP becomes ADP. The supply of ATP in your muscles is limited by how fast your body can covert proteins, fats, and carbs into it, and when your muscles suffer a shortage, they will feel stiff and unresponsive. The creatine works by delivering P to your muscles directly, so that the ADP is rapidly converted back to ATP, taking the load off the rest of your body to produce it. This will give you a bit of a boost during your workout. However, the effects are not particuarly dramatic, because the ability for creatine to convert ADP back to ATP is much crappier than your body’s ability to do it naturally.
