Berocca and alcohol

I've been taking 1 Berocca per day for approximately 2 months in a row. I just had a thorough health exam and my physician noted that I had elevated liver values as if the liver had to work too hard and that my kidney values were strange, more than bad. The kidney values come from a urin test and one indicator is colour, which of course is different when on Berocca. He can't find any specific explanation for the liver value though (not hepatitis, not alcohol nor pharma related.)
