If you have found all the ingredients then it must depend on where you are in the world. You mix according to taste that is what schulzes stated to his students.
Have you found the yeast or are you asking what amount to use.?

Acerola Cherry is probably only available at wholesalers. I have never seen it listed on any site I have been to yet. (Amway used to sell the pills a while back.)

Personally I would skip the nutritional yeast completely. It's only used because it is a very cheap filler.

You could start out mixing the rest in equal proportions. Or you could go to a website like iherb.com and check out the labels from other green powders to get a sense of proportion.

Most companies that make top quality green powders clearly state the exact amounts of each ingrediant used. But Dr Schultz is deceptive with his "...in a base of nutritional yeast" labeling.
