❓ Frequently Asked Questions

Does blending kill the probiotics?

High-speed blending causes minimal loss of probiotics. The benefits of consuming the smoothie far outweigh the negligible reduction in culture count.

Can I use milk kefir made with non-dairy milk?

Yes, absolutely. Kefir made with coconut, almond, or soy milk works perfectly well in this recipe, maintaining the same creamy texture and probiotic benefits.

Can I make this smoothie ahead of time?

It’s best to consume the smoothie immediately. While refrigeration for a few hours is okay, the texture will separate and the flavor may become slightly more tart.

How can I increase the protein content?

Add a tablespoon of nut butter (peanut or almond), a scoop of protein powder, or 1/4 cup of cooked oatmeal before blending.

What other fruits work well?

Berries (strawberries, blueberries), mango, and pineapple all blend excellently with the tangy flavor of milk kefir.

Why does my smoothie taste very sour?

This means your milk kefir was over-fermented. To compensate, use sweeter fruits (like banana or mango) or increase the amount of sweetener (honey/maple syrup) used in the recipe. For information on fermentation timing, check our guide on making milk kefir.

Is this recipe suitable for children?

Yes, this is an excellent way to introduce probiotics to children. If the kefir flavor is too strong, dilute the kefir with plain milk before blending.

How much is 250 ml in cups?

250 milliliters is approximately 1 cup or 8 fluid ounces.

Can I add grains or seeds?

Yes, adding chia seeds, flax seeds, or a small amount of rolled oats can boost fiber and thickness. Let the seeds sit in the kefir for a few minutes before blending to soften.
