About 6 years ago I also had high liver numbers on my 6-months labs, and my doctor, a highly respected endocrinologist who didn't like supplements, decided it was probably those dang vitamins I took. He suggested I stop taking them for a while and retest. I didn't stop but did retest and the numbers were some improved so he thought I was on the right track. However, a week before Christmas in 2010 I had to have an emergency gall bladder operation. The pain was severe--don't wait too long to find out why those liver numbers are out of line. Joan
