About: We created this calculator to help people dose creatine properly relative to body weight and not waste their money. Since excess creatine is just excreted in urine, labels often use a “One Size Fits All” approach in their recommended dose. On top of that, it’s typically too high for even a 350 lb football lineman. Bottom line, most people are wasting their money and literally pissing it down the drain.
Creatine is a nitrogen rich organic compound that is naturally occurring and synthesized in the body. It plays a vital role in the creation of ATP by rephosphorylating ADP. It is especially important for short duration, high intensity exercise. In such events, as creatine stores decline, energy and performance also decline. If creatine stores in the body remain elevated, performance will also remain elevated. This is where supplementing with this highly studied compound come in handy.
Creatine is found in abundance in meat and fish, but supplementation is also very popular to ensure maximal levels of the compound are in the muscles prior to athletic endeavors. Supplementing may lead to less fatigue and enhanced recovery in resistance based exercise. Overall, your workouts and performance will be better. This does not mean more is better. Creatine supplementation will increase the content in the muscles by about 20%. Once the muscles are fully saturated, excess creatine will be excreted. If you stop supplementing, levels will revert to baseline in about a month.
Body Composition Changes: Changes in body composition are expected with longer term creatine supplementation. Greater water retention within muscle cells is part of this change. Also, greater creatine levels in the muscle may increase contractile protein synthesis. Don’t worry, this isn’t negative like putting on more fat. This, to most athletes—especially guys, is a huge benefit.
Side Effects: A few possible adverse effects have been reported such as mild gas, diarrhea, and muscle cramps; however controlled studies have yet to find any significant side effects. As far as long term side effects go, more research is needed. A major concern is that the increased nitrogen content can strain the kidneys, but no renal dysfunction or failure has been reported in studies ranging in length from 5 days to 5 years.
Note: We use a loading dose because if you just take the smaller amount, it will take a month for the muscles to become saturated as opposed to just 5 days.
