Just had blood work done and my creatinine level is 1.1 mg/dl. The range it says to be .5-1.5
I eat about 200g of protein daily and take creatine 3x a week after working out. not sure about others here but my creatinine levels has never been elevated as far as I remember however, I take daily magnesium and potassium because my potasium was low in the past. Now even with the suplementation my potassium is 4.1mmol/l and the range is 3.5-5.5. So to me is still a concern becasue I'm not even sweating that much to lose potassium. So, I definintely think that there is a correlation among all these.
Before jumping to conclusions, I would look at all the numbers and try to make sense but from what I heard accutane is nasty and usually test would not put stress on the kidneys in normal conditions.
I would definitely take those eleveted numbers seriously and make sure there isn't an underlying issue here becasue I eat lots of protein and take creatine without my levels being elevated
Good luck bro
