Hey Flapjack -
Ok, I found out what my bf is taking as far as supplements go (and I think brands are important regarding quality - the ones I have listed are just what he has found works for him):
Solaray brand Liver Blend SP-13 (includes MILK thistle)
Planetary Herbals Bupleurum Liver Cleanse
Twinlab L-Glutathione Caps
NOW brand NAC (N-Acetyl Cysteine)
I hope this helps! You are definitely on the right track by avoiding interferon with such a low viral load. My bf also mentioned a newer drug treatment in the UK that you can read about here:
http://www.timesonline.co.uk/tol/news/uk/article648941.ece. His doctor said that this drug has passed clinical trials in europe but has not yet been tested or approved by the FDA in the US (what else is new, right?), but he's been telling all his patients about it. Sounds promising for folks w/ Hep C.
Good luck with everything and take care,
S.
