i've found a top 5 list, with best protectors (TUDCA, Milk Thistle, Essentiale Forte, N-acetyl cysteine (NAC)[FONT="] , [/FONT]Liv-52[FONT="][/FONT])
was thinking this is just a marketing tool, to sell TUDCA, that is why on the first place.
also i am trying to check if maybe for some this is individual, and fit different products.
