As for supplements to take, I quit statins couple years ago and have had great success with niacin (b3). I take 2000mg daily, it HAS to be the regular niacin, the non flush won't do anything for you as far as cholesteral because of the way the body metabolized it. You will Get used to the flush after couple months so it won't bother you. All my numbers are good now I don't worry about cholesterol,.
As far as a fatty liver, few years back my LFT were all elevated and high. I was taking oral nsaids(napraxon) daily for a couple of injuries for well over a year and really jacked with my liver. Stopped the nsaid and started taking milk thistle in the am and pm and LFT returned to normal.
