I've never used Oregano Oil, so i dont have an answer for that, but the protocol for GSH
(Glutathione) is 30 mg. per pound per day. So if you were 115 lbs. you would need apprx. 3450 mg. a day.
You should space the doses out. I used to take 1000.mg 4 times per day when i was on that same dose. Make sure to take 500mg. Vit.C to help with the absorption of the GSH. I hope you find great results like some of us have <img src="i/expressions/face-icon-small-happy.gif" border="0">
