Which one of these would be the best to go with ? Iv'e always used the liv52 DS version but after reading up on NAC it looks a lot better. Question is can it xhibit potent hepatoprotective properties against chemically-induced hepatotoxicity and restore the functional efficiency of the liver by protecting the hepatic parenchyma and promoting hepatocellular regeneration like liv52 Ds claims to...whats you're input guys and personal choices or is there anything better.
