Clinical verdict
Juice cleanses have NO evidence for 'detoxification.' Greens powders are nutritionally equivalent to eating vegetables. Juice-only fasting risks hypoglycemia, electrolyte disturbance, and eating disorder reinforcement. The 'alkalizing' claim violates basic physiology — blood pH is tightly regulated [1].
