I personally believe that glutathione is superior, it also can helps your skin, I had some hyperpigmentation and after a couple months of 600mg a week inj glutathione it started to clear up so that’s just kind of an extra bonus. Check out some of the Korean beauty sites like meamo or skin reboot , they all carry glutathione and it’s really not that bad on the wallet at all ! All I’ve ever used for liver support is 1000mg Tudca and 600mg weekly inj glutathione, but if you don’t have any skin issues and aren’t a fan of pinning you could get very similar results with just nac and Tudca or liposomal glutathione capsules
