Kefir is a fermented milk drink made with kefir grains — a symbiotic culture of bacteria and yeast. It contains significantly more live cultures than yogurt, with up to 61 strains of bacteria and yeast documented. Originally from the Caucasus mountains, it has been consumed for centuries as a medicine for digestion, immunity, and longevity.
Why it matters
Highest Probiotic Density
Up to 61 documented strains of bacteria and yeast — far more than standard yogurt.
Gut Barrier Support
Strengthens the intestinal lining, reducing leaky gut and systemic inflammation.
Lactose Tolerance
The fermentation process breaks down lactose, making it tolerable for most lactose-sensitive people.
Anti-cancer Properties
Kefir peptides have demonstrated anti-tumour activity in multiple in vitro studies.
How to eat it
Drink 150-200ml daily, ideally in the morning. Use it as the base for overnight oats, blend into smoothies, or pour over fruit and seeds. Kefir made from oat milk or coconut milk works well if you avoid dairy. The slightly sour, effervescent taste is a sign the cultures are alive and active.
Kefir has been shown to reduce symptoms of lactose intolerance, improve gut barrier function, and significantly increase microbiome diversity — even in people who don't respond well to other probiotics.
