Creatine is involved in making the energy muscles need to work.
Vegetarians and other people who have lower total creatine levels when they start taking creatine supplements seem to get more benefit than people who start with a higher level of creatine.
Skeletal muscle will only hold a certain amount of creatine; adding more won't raise levels any more.
This "saturation point" is usually reached within the first few days of taking a "loading dose."
