to much to supplements and creatine levels high

hi.. does any1 think one can take to much supplements? and also my last flare in oct i had a blood test and they were not to happy with my kidneys,so i did more test and my doc says that my creatines levels were high but that it more than likley was cause by my flare and mayb all the tabs as i was on asacol 800mg 6 a day and pred 5mg  6 a day but could it have been the supplements too, i just feel like im a walking bin for alsorts of tabs. and i hope my high levels are down when i get my next blood test which is on monday when i get my scope done. Can anyone shed any light on this THANKS ALL.

Mine is always high because I consume creatine and they are measuring the metabolite creatinine produced by the kidneys. I stopped and hydrated well and the next score came in just below the max. I had a relative-in-law who had a score in the 90's and went on dialysis so the fact that I am always somewhere in the teens is not troubling for I am at least stable.
