Can you not ask the dosages that we’re given to those who received the NAC?
That would be good to know.
NAC is also reported to be helpful in recovering from several respiratory illnesses, including China virus.
Dosages for that vary, depending on whose protocol you read or follow.
NAC has been pulled from Amazon and a few other online supplement vendors.
I think you can gugle it to find who still sells it.
NOW, Jarrow and Doctor’s Best seem to be popular brands, from what I’ve read, here.
I hope you have vi to yes success with your son’s treatment.
Keep us posted, please.

I purchased from Swanson. Price and delivery were good.
