For liver detox, you might consider N-A-C, an amino acid precursor to glutahione. Glutathione is what the liver uses to detoxify many wastes, alcohol, tylenol, etc. It is used in the emergency room in cases of tylenol and mushroom poisoning to boost the liver's ability to process the toxins.
N-A-C must be taken with at least 3x the Vitamin C, so taking it when you're megadosing on C is a good idea.
