I had elevated liver enzymes (i.e. signs of liver damage) for two annual physicals in a row. My doctor tested me for all the usual culprits including all types of hepatitis and everything came back negative. She then asked me if I took a daily multivitamin. I told her I did and she told me to stop taking it. That was 12 years ago and I have not had elevated liver enzymes since. According to my doctor, people that get enough vitamins and minerals through their diet can actually overdose on the sledgehammer of vitamins in a typical Centrum-style multivitamin. This can then cause liver damage which shows up in an ALT/AST blood test. I think it's prudent to only take vitamins for which you know you are deficient either because of dietary restrictions or through actual testing. For example, my vitamin d level gets low in the winter time so I take vitamin d3 for that.
