Neuro NAC(ET)
So as a scientist, who has worked on Glutathione in a research setting I am well aware of its significance, physiologically. I was having issues with quite bad insomnia. The Neuro NAC(ET) has helped me immensely (everyone is unique so not everyone might experience the same result), as reduced systemic inflammation helps regulate many bodily functions including hormone homeostasis eg., melatonin. Several disease conditions slowly fester below the surface before raising their ugly head. This supplement may well stave several of them off by mitigating the damage from free radicals and oxidative stress. Like a lot of things in life, things go on behind the scenes to which we know little about but life goes on, this might be the case of the Neuro NAC(ET) for a lot of people which may not see a benefit, because the effects are taking place at a cellular level through out our bodies. The fact that the FDA made NAC a drug in the 60's speaks to the beneficial nature of this compound, and to the smart chemists who figured out adding an ethyl ester to it drastically increases the bioavailability by 75% over NAC is simply elegant science, so making it a case of less is more. I can't speak to any other product in the line up but I have this auto-ship and intend to keep it that way. The vanilla flavor is very pleasant, the reported bad sulfurous smell/taste, I have no idea what these people are talking about. I can't speak for other peoples experience(s), but my shipping experience was fine, the item arrived within 1 week of purchase.
