The directions say one or two scoops per day.

Its rammed FULL of all sorts of vegetable powder, fruit powder, and other good for you stuff powder. all pulverized into a powder. Cant help but wonder what such a process does to the nutritional value of the items in it.

After drinking my juice with my ONE scoop. I felt full like I had a good breakfast. its several hours later, and I am not hungry or craving a snack.

It can be used as a meal replacement or an addition to your normal diet. I think if you are replacing a meal, its two scoops, but if you have a small stomach or are a smaller person one scoop should last you for one meal. That way you can replace 2 meals per day and have a healthy dinner.
