In a strong blender, add the fruit juice if using, yogurt, protein powder, and ice cubes. Blend until smooth.
Add the fresh and/or frozen fruit, banana, seeds, and honey. Blend until smooth. If the smoothie is too thin, add more protein powder. If it is too thick, add juice, water, milk or other liquid one tablespoon at a time until your desired consistency is achieved.
Pour into glasses, garnish with fruit, and serve immediately.
