You can opt to use flavored yogurt over a plain one. You can go for vanilla, strawberry, or any other that will blend well with the other ingredients.
You can also opt to use milk if you like your smoothie lighter. Coconut, soy, almond, and oat milk can be alternatives if you are on a plant-based diet.
You can do away with milk or yogurt and use water instead, that is, if you don't like the taste.
In this recipe, I used natural fruit; you can use fruit purees instead. However, to get the real taste using fruits is a better choice.
If the smoothie is not sweet, you can add honey, although it might be overly sweet.
You can choose the number of berries, especially those you prefer most.
You can enjoy the smoothie best when served cold. Apart from using ice cubes, you can refrigerate it for 30 minutes and then take it.
