📊 How it ranks (our editor score) — 80/100Tap to see the breakdown
🌱 What it is
Kefir is milk fermented with "kefir grains" -- a cluster of bacteria and yeast -- producing a tart, drinkable, yogurt-like ferment with a broader range of live cultures than most yogurt. A dairy-free version, water kefir, ferments sugar water instead of milk.
✨ Why it's good for you
- Provides a wide variety of live beneficial bacteria and yeast (probiotics)
- Dairy kefir supplies protein and calcium
- May be easier to digest than plain milk for some people with mild lactose sensitivity, since fermentation breaks some of it down
- A versatile base for smoothies or a simple drink on its own
🥗 Nutrition
Per 1 cup, plain dairy kefir (243g) · about 104 calories
- Protein 8.9g
- Calcium 296mg

🥄 How to use it
Drink dairy kefir plain, blended into smoothies, or poured over granola; water kefir can be flavored with fruit and enjoyed chilled.
⚖️ Cautions
- Like other yeast ferments, dairy and water kefir normally contain only trace alcohol, but this can rise somewhat with longer home fermentation -- worth checking if you are avoiding alcohol strictly. Dairy kefir is not suitable for a milk allergy and may still bother significant lactose intolerance; choose water kefir instead in those cases. Those with a compromised immune system should be cautious with any live-culture ferment.
📚 Why we trust it
- Wide diversity of live cultures, well studied for gut health
- Traditional fermented dairy (or water-based alternative)
