Kefir: What it is, why people drink it, and how to use it
Want a simple way to add probiotics to your day? Kefir is a tangy, drinkable fermented milk (or water) product that’s packed with live cultures, vitamins, and a creamy tang. Unlike plain yogurt, kefir usually contains a wider mix of bacteria and yeasts, so many people find it especially helpful for digestion and gut comfort.
How kefir helps your gut and health
Kefir supplies live probiotic strains plus nutrients like calcium, protein, B vitamins and vitamin K that support bones, energy and digestion. The fermentation process lowers lactose, so people who are mildly lactose intolerant often tolerate kefir better than milk. People report fewer bloating episodes and more regular stool after adding kefir to their routine.
Keep this in mind: kefir is a food, not medicine. It can support gut balance but won’t replace treatments where medical care is needed. If you have a weakened immune system, are pregnant, or take multiple medicines, check with your clinician before using kefir regularly.
How to make and store kefir at home — quick, no-fuss
Homemade kefir is cheap and easy. Use dairy or water kefir depending on your needs (water kefir is dairy-free). Basic milk kefir method: add 1 tablespoon of kefir grains to 1–2 cups of fresh milk in a glass jar, cover with a loose lid or cloth, and leave at room temperature for 18–36 hours. When it smells tangy and has thickened slightly, strain the grains with a fine plastic or stainless-steel strainer, bottle the liquid and refrigerate.
Want sweeter kefir? Do a second fermentation: seal the strained kefir with a few pieces of fruit or a little juice and leave it 12–24 hours to develop flavor and mild fizz. Strain again and chill. Grains go back into fresh milk to start again.
Storage tips: keep kefir refrigerated and drink within 1–2 weeks for best flavor and probiotic activity. Grains stay alive in fresh milk in the fridge for a few days; for longer breaks, store them in a small amount of milk in the fridge or dry/freeze them following a tutorial.
Uses and practical ideas: drink plain kefir with breakfast, blend it into smoothies, use it as a base for salad dressings, or swap it for buttermilk in pancakes. For dairy-free options, try water kefir or coconut milk kefir starters. If you’re on antibiotics, take kefir several hours apart from the pill—antibiotics can kill probiotic bacteria and reduce the benefit.
Quick calorie note: one cup of milk kefir ranges roughly 100–160 kcal depending on milk fat. Start small—half a cup daily—and see how your body reacts. If it agrees with you, increase slowly. Simple, cooling, and versatile—kefir is an easy habit to try if you want more probiotics in your food without complicated supplements.
