Is kefir good for babies?
Kefir contains a diverse range of live bacterial and yeast strains — significantly more than regular yogurt. The fermentation process partially breaks down lactose, making it easier to digest than plain milk. Rich in calcium, B12, protein, and phosphorus. Its slightly tangy flavour is well accepted when introduced early alongside sweeter foods. Choose plain, unsweetened, full-fat kefir for babies.
