Nestle wants you to take two servings of 600 mg glycine/600 mg NAC a day, giving you 1,200 mg glycine & 1,200 mg of NAC, a day.
I hadn't read their directions—just their serving information. Nestle does say they found the therapeutic response with two servings a day to be good, though.
The drink version has 1,200 of each in just one packet.
Thanks!
