A little late to the party, but, fwiw, I have taken oral Glutathione* because I'd heard it was one of the more effective anti-oxidants. It is also one of the pricier supps, but gawd is good ... our bodies will convert some of the cheaper NAC into Glutathione as long as the FDA will allow some merchants to sell NAC to us.Take all 3. I do, NAC, Tudca and Milk Thistle. I hear injectable glutathione works quite well too but I have never tried that.
I also have been taking all three.plan on taking milk thistle too, product im gonna get is 1000 mg per cap is that too much? they recommend 3000mg per day.
will talk mt/nac/tudca next cycle when using orals.
