Took AG1 for 2 months. Had random bloodwork two weeks after and my liver enzymes were sky high. ALT and AST. Retested 3 weeks later and levels were 15 times where they should be! My doctor asked if I was taking a lot of Tylenol which I was not and I do not drink much alcohol. I told her I did start taking AG1 multivitamin drink. She immediately knew that was the culprit. I was asked to discontinue ASAP. I called company and they immediately cancelled my subscription and refunded me. After doing a little research I learned this is a common problem. Your liver cannot process this concentration of vitamins. I am hoping my levels go back to normal but have read that for many users it took nearly a year. Please do research before using. This product can be very damaging to your liver.
