7. Beet Greens: The tops of beets are loaded with antioxidants, vitamins A and C, and have a pleasant earthy taste. They blend well with both sweet and citrus fruits.

8. Parsley: While typically used as a garnish, parsley is a wonderful addition to smoothies for its detox properties and high levels of vitamin C, K, as well as iron. Its fresh flavor compliments sweet fruits like apple or pear.

9. Watercress: This aquatic plant imparts a peppery flavor to smoothies and is rich in nutrients such as vitamin K and antioxidants. It’s an excellent partner for sweeter vegetables like carrots or tomatoes.
