Could my protein supplements (whey and creatine) affect my bilirubin blood levels?

Ive been bodybuilding for 2-3 years now and looking at blood tests before taking supplements i already had high bilirubin (13.9 mg/L) and creatine levels. about 2 years later I took the test again. been taking supplements for about a month. i have a bilirubin of 18.45 mg/L. could the creatine/whey be causing this and if yes is it bad? how do I lower them? Is it normal for a body builder/athlete to have such levels?
