Was your system empty of it whhen you tested the first time? What I mean is, if you recently took it a few hours before...maybe longer depending on metabolism, you will not need it when you test it. I am instructed not to take anything before muscle testing or biofeedback. If I take something and still need it , I can increase the dose. I do it with biofeedback so I see a number that symbols my need for the suppliment/food/mineral.
Interesting about primal defense. My Mom dislikes it, she thinks it made her more yeast-y. Did it increase your candida at first or no? It could be our imagination, but we both thought that it did. I had an itchy scalp after using it and increased hunger. I should of stayed longer on it.
I do love Garden of Life. They are fabulous products and nice people.
