Kefir grains – will heat kill kefir benefits?

Can I cook dishes while heating up my kefir? It’s generally believed that heating foods kills the healthy bacteria after a certain temperature. Our research found that cooking will kill some of probiotic benefits of kefir. We have to think about kefir grains like it is living microorganism e.g. mix of healthy kind of fungi and bacteria. Like most of living organisms, kefir have its top heat exposure point when they will simply stop being active.

BUT! The good news is that there are other helpful nutrients in kefir that you will benefit from, even after cooking. Do not forget that kefir grains are rich in sugars, proteins, lipids, vitamins, and minerals. The important nutrients in kefir that will not go away due to heating are: calcium, phosphorous, magnesium, tryptophan (an amino acid), folic acids, biotin, and Vitamins A, B2, B12, D, and K. Your entire body as well as nervous system benefits a lot from these, since the tryptophan calms your nerves while calcium and magnesium stabilises your entire system.

If you want all probiotic benefits from kefir try adding kefir after your dish has been cooked. This method can be applied mostly to soups. But drinking plain kefir every day might get boring, experiment with dishes – even if you will get one kefir benefit, it will be better than none.
And as always … thank you for stopping by !


  1. Is kefir beneficial and safe to feed to horses? If so how much should I feed?

    • Hi Sarah,

      Thank you for your question! There are numorous posts on the internet that people feed their pets with kefir. Unfortunately I have not heard of any scientific studies done on animals combine with kefir benefits. So if you follow people logic, you can make an assumption that: if it is healthy for humans it should be healthy for animals. Otherwise please contact your trusted veterinary physician. Good luck!

      Best wishes,

  2. Thank you for helping me decide to not buy kefir any more. It might as well read: “Yes, the popular nutritional benefits of kefir are lost by heating but please still buy it since our interest is in promoting kefir and not how it benefits consumers.”

  3. What is the heat tolerance of the probiotics? I would like to make my instant oatmeal with the Kefir meaning 1 minute in the microwave…. too much?

  4. Cooking with Kefir
    That’s commonsense that good and bad bacteria are eliminated x heat
    but Trace elements remain present.
    I make Irish soda bread with the excess kefir and this adds a special taste= better than just using lemon-juiced soured milk.
    Just have a kefir drink with breakfast and excess for fermentation, baking and dogs food extra.
    No worries

  5. @Julie Have you tried overnight oats with kefir. Just soak the oatmeal overnight in kefir, requires no cooking. Just search for overnight oats recipes and substitute the yogurt and milk for kefir milk.
