Is that supplement even available?

I'm sorry but the FDA has made this unavailable to Americans . . well that's not true. The illegals coming over the border can have it for free along with cell phones, housing, debit cards, health care, etc . . .

Yes, here:

You can make it having a 600 mg NAC capsule and a 1/4 teaspoon of glycine powder or a 600 mg capsule of glycine.

[catnipman]

it’s just glycine, an amino acid, plus n-acetylcysteine, which can be bought inexpensively from swansonvitamins ...

Glycine and NAC are both available, though our beloved FDA is starting to limit the sale of NAC.
