The three Ks in this smoothie refer to the kale, blackberries, and cucumber, which all deliver a healthy dose of vitamin K. Vitamin K protects against cancer and heart disease and helps in blood clotting. If you want a colder smoothie, try using cooled green tea or coconut water ice cubes for flavorful additions.
2 cups kale
2 cups frozen blackberries
1 cucumber, peeled
2 teaspoons almond butter
2 cups water
