There are a lot of lifestyle things that could help. I'd start by making sure your diet is cleaned up and get rid of foods that cause higher amounts of inflammation. (Sugar, highly processed foods, etc...) You could try some intermittent fasting here and there to see if that helps and include some support supps that benefit liver function. NAC and Tudca would be the first two I would throw in. Make sure your getting in enough fiber and also cut out any compounds that are known to increase your liver enzymes.
