Look into Liv-52 as well. You can run both NAC and Tudca by the way. I like running liv-52 and Nac together. I've recently shared my Liver protocol. It has worked for me for a long time, but everyone is different. If you have had liver damage, stay away from orals...period! Your health should be number 1. Supps gave you solid advice...also, I hope you're drinking at least 1 gallon of water per day...2 would be better. This is one of the things that most pros do....keep their bodies hydrated. You've got to flush the toxins that you're putting into your body. If you still decide to run orals, please use it with food and always take omega-3 with orals...also, tumeric should be used daily to help clean out the body of toxins and inflammation.
