NAC is cheaper and better. But TUDCA will certainly do the job very well. Body weight is not relevant. 250 to 500mg on and a couple weeks post cycle as well is the common dose.
Ok are you saying N-Acetyl Cysteine is good for liver cleanse. I use to take it for years for hair health but not liver health. I have not been able to find tudca in local health food store. If NAC is good for liver i am going back to it.
