I see that some of you recommend getting your Glutathione levels up while taking TF. I recklessly bought a number of supplements at once and have been starting them one at a time to see if they're helping or making things worse. I see that most of you recommend taking NAC or some other precursors. Well, in the bunch of supplements that I bought is a bottle of L-Glutathione. SInce I already have this, I would prefer taking this before going out and bying a bottle of NAC (my bottle will last 2 months). I don't know anything about the science about this, but I'm wondering why it is better to take the precursors rather than the real-deal. Is it okay to take L-Glutathione with TF?
