juicing increased dizziness

Is that all you've had today? And is that all that was in the green juice?

My blood sugar is so wonky...spirulina has helped some ...if its that see jims post

I can see two possibilities that may be occurring. You have nutrient deficiencies and when juicing, you are increasing your nutrient levels which can increase glutathione and cause a herx or the levels of cysteine in the juice is increasing glutathione which can cause a herx.
