A little backstory…

Guy, I made this smoothie last autumn when it hit me with kind a lot of colds. They just kept on coming, and I was never sure if I would get cold or if it was “just” a simple cold or flu. So I decided to make a super-strong immunity booster smoothie that I would drink over a few weeks,…
This smoothie helped me SO MUCH. I am least I believe it was di to this smoothie. I felt more energised, and it tasted so good! I am not a juice fan. I rather consume a thicker, juice blend, as they are more filling and I love eating the fruits “flesh”. :D… that sounds strange… but I guess you know what I mean.

Did you notice, after pumping your body with immunity booster smoothies, that you get through the fly season better? Or do you think, it no doesn’t matter?

Is this Green Kiwi Banana Smoothie recipe a breakfast evening or lunch recipe?  

You can make this immunity booster smoothie as a low-calorie breakfast smoothie. 

Because it’s high fibre, and therefore filling. Although it just contains a moderate (13% =6.5grams) of protein. 

Either scoop some protein powder into your smoothie, or greek yoghurt, hemp seeds or chia seeds to make this Kiwi Banana Smoothie more filling.

You can enjoy this smoothie also to any other time of the day. 

It’s great as little as an in-between snack or a smaller meal replacement.

Also, you can have it in the evening as a healthy dessert option, as it has a good sweetness. 

What does the Smoothie recipe taste like?  

Speaking about the taste…

Do you love the flavour of a ripe, sweet kiwi?

Then you’ll love this smoothie recipe!

Because it tastes truly of a sweet kiwi drink, with the sweetness of the ripe banana.

Because there is mango in the recipe, it makes the smoothie nice creamy and fruity.

You can use any milk. Coconut milk is also a good call, but it will add more calories. That is a good call if you want to increase your energy level, and turn this into a meal replacement smoothie, or breakfast smoothie, as it’s high in fats.

How do you know if a kiwi is ripe?

When you buy kiwis, always make sure, you are very slight, squeeze the kiwi in the centre of its belly to see if it’s ripe. 

If it’s hard it still needs time to ripe. The softer, the riper. Kiwis ripen within a few days. You can even freeze them, to stop the ripening process and blend them for smoothies. But because of its high water content, the kiwi will be super hard. The great thing is that you can make super thick smoothie bowls like this.

Cuisine American, mediterranean diet, middle eastern
Servings 2 people


  • 1 Blender high speed or any other blender


  • 1 cup milk unsweetened (or any other)
  • 5 pcs kiwis ripe, fresh
  • 1 cup spinach (fresh used in the recipe) frozen works too
  • 1 cup mangos ripe, frozen
  • 1 cup bananas ripe, frozen
  • 1 cup ice optional (or to cool the glass)


  • Pour your milk of choice first into the blender.
  • TIP: To make the smoothie a little thicker, you can freeze half of the milk, into ice trace (like silicone once or plastic), and pour half a cup into the blender, to keep it going. (if you have a good blender, or use mini ice cubes)
  • As the second step, drop all (fresh) 5 kiwi's into the blender. As a whole, or you can spoon them in. Or just cut off the ends.
  • Now it's time to drop in the spinach.
  • BLEND ALL until smooth, to ensure the spinach and kiwi (skin) are fully blended.
  • Then add the mangos, and bananas to the blender.
  • Blend again until smooth, on a low setting. Use your temper.

Recipe Tips 

Ensure to choose ripe kiwis, bananas and mangos. That makes the smoothie sweeter.

The more liquid (milk) you add the thinner smoothie becomes. You can play around with it. 

Start with less liquid than the recipe calls for because you can always add more.

 For thick smoothies, use your temper as often as you can: By pushing down the smoothie blend. To make sure everything is SUPER GOOD blended. Otherwise, some parts are super smoothie, while others are lumpy. Then you’ll end up with a thin smoothie.
