Hi Johnny,
I haven’t seen any evidence so far showing turmeric (at least in the doses you would be getting from eating it) having any significant effects on Hep B. In fact, there have been a couple of cases where turmeric supplements have damaged the liver and induced ALT flares (reported here and here).
Regarding the choline, it is true that a choline-deficient diet will damage the liver. But once you have enough, it’s not clear that eating more is better for your liver. I haven’t seen any trials to suggest that that is the case.
