Wash all your fresh ingredients thoroughly under cold water. Chop the celery, green apple, pineapple, and cucumber into smaller pieces. Peel and slice the ginger.

If using a juicer, add the chopped celery, spinach, green apple, pineapple, cucumber, and ginger into the juicer. Process until fully juiced, about 2-3 minutes.

For a blender, place all prepared ingredients into the blender with 1-2 cups of cold water. Blend on high for about 1-2 minutes until smooth.

Strain the mixture through a fine-mesh sieve or nut milk bag if you prefer a clearer juice.

Pour the juice into a glass and serve immediately, optionally garnishing with cucumber or lemon.
