Wash and prep. Rinse all produce well. Peel the lemon and ginger.
Roughly chop the cucumber, celery, and apple into chunks that fit your juicer or blender.
Juicer method. Run cucumber, celery, apple, spinach/romaine, ginger, lemon, and mint through your juicer. Stir in coconut water at the end to adjust sweetness and hydration.
Blender method. Add all produce to a blender with coconut water. Blend until smooth.
Strain through a fine mesh sieve or nut milk bag for a lighter juice, or drink as-is for more fiber.
Taste and adjust. Add more lemon for brightness, more mint for freshness, or a splash of coconut water for sweetness. A tiny pinch of sea salt can enhance minerals and flavor.
Serve chilled. Drink slowly on an empty stomach or between meals for best comfort and absorption.
