its recommended i believe 4xs a day...or build up to that but i can only do it once, and 2xs on one day.
i take 1/2 tsp. Sea Salt , 1/2 buffered vit c and i empty 1000 pot from a pill and drink it down.
i did get a headache the day after i did it twice so be careful. they don't like it, thats for sure.
there are numerous posts on vit c protocol, so you might do some research.
