- Fresh mint: Adds brightness; basil is a fine substitute for a different herbaceous note.
- Collagen powder: A clean protein option that boosts protein content and supports gut and skin health.

Flavor Variations
Berries: Strawberries, raspberries, or blueberries pair nicely and add depth. Try a mixed berry combo for more complexity.
Citrus twist: A splash of lime, lemon, or orange juice brightens the drink.
Expert Tips To Make It
Check coconut water labels for added sugar; many brands add sweeteners. Use unsweetened coconut water for the cleanest flavor.
If using fresh watermelon, place the chunks at the bottom of the blender to help everything blend evenly.
Both collagen and other protein powders work, though different powders change texture and taste slightly. Adjust amounts to your preference.
If you are breastfeeding, note that mint can reduce milk supply for some people. If concerned, omit the mint and add lime juice for brightness instead.
Meal prep hack: Freeze prepared portions of fruit and herbs in labeled bags for quick smoothie assembly.
