This orange smoothie with kefir is a sweet and tangy, immune-boosting smoothie, and is packed with probiotics and vitamin C.

This cold and flu season has been rough.

Actually, that’s an understatement– it’s been ridiculous, and staying healthy has become priority number one.

One of my favorite ways to boost my immune system is by packing my diet full of extra vitamin C– through food instead of supplements whenever possible.

This vitamin C-packed Banana Orange Smoothie is a delicious, fast, and easy way to add a few extra vitamins to your diet.

Does it Matter What Kind of Orange I Use?

Not really!

The recipe calls for one navel orange, but you could also use cara cara oranges, blood oranges, or any other sweet, medium-size oranges you can find.

If you’ve got mandarins or tangerines, simply use 2 or 3 instead of one orange.

Keep in mind that some oranges are sweeter than others, so taste it before you skip the sweetener.

What Is Milk Kefir?

Kefir is a fermented milk drink— similar to yogurt, but thinner and more drinkable.

Look for plain, unsweetened milk kefir near the milk section at your local grocery store, or learn How to Make Milk Kefir at home.

Smoothie Topping Ideas

I’m not always big on adding toppings to my smoothies– I like them to be 100% drinkable, with no choking hazards.  Ya know?

BUT.

This orange smoothie is SO DELICIOUS with some flaked coconut on top.

It’s also delicious with some cacao nibs or some tiny chocolate chips.
