5 g of creatine enough?

The body doesn't synthesize it's own creatine. Creatine has to be ingested daily. So, there is no creatine synthesis recovery. That is the reason that some people see a huge difference when supplimenting creatine and some see no difference at all. It's dependent on your eating habbits. Creatine is found mainly in meats and vegitarians don't eat meat, so they have very low creatine. If a vegitarian suppliments creatine and a person that eats a lot of red meat suppliments creatine, they are going the have very different results. The meat eater isn't going to see much difference if any and the vegitarian is going to see a huge difference. If we all synthesized our own creatine, this would not be the case.

you are wrong my friend... creatine is a small, amino acid-like molecule that is both synthesized in the body and derived from foods... relaxed muscle fibers produce more ATP than they need for resting metabolism. The excess ATP is used to synthesize creatine phosphate...the enzyme creatine kinase (CK) catalyzes the transfer of the high-energy phophate groups from ATP to creatine, forming creatine phosphate and ADP...shall i continue... creatine phosphate is 3-6x more plentiful than ATP in the sarcoplasm of a relaxed muscle fiber. when contraction begins and the ADP level starts to rise, (CK) catalyzes the transfer of a high-energy phosphate group from creatine phosphate back to ADP. this direct phosphorylation reaction quickly forms new ATP molecules. Together, creatine phosphate and ATP provide enough energy for muscles to contract maximally for about 15 seconds. this amount of energy is sufficient for maximal short bursts of activity- for example a 100 meter dash... nothing personal but accurate info. is always the best info.

Okay, no, the body doesn't synthesize creatine (once again). No, ATP isn't used to CREATE creatine. No, creatine kinase doesn't catalize anything from ATP into creatine, it turns plasma creatine into usfull form for the muscles to use (I'm too tired to get into the micro biology of it right now, but I'll do it sometime in the morning if you like). But I will tell you that you have things a little confused. It does alter ADP, but it doesn't turn creatine phosphate into ADP, it gives it's phosphate atom to ADP to turn it back into ATP so it can take one more pass before completely breaking down the phosphate chain. Yes, the creatine does help the muscle work a little better and creatine supplimentation does help mainly with short bursts of energy. And yes, accurate information is always best, which is why I feel that I must point out that you are not giving accurate information.
