It's not usually going to be just a liver problem, but a whole body problem. The gut has to be repaired. Normal HCL levels need to be restored. Detoxification needs to be increased. The bowels need to move 3-4 times a day. Liver support supplements that can be helpful include UltraClear Plus by Metagenics, SAT by Thorne Research, etc. Homeopathics can be helpful. Diet is a big factor.
