Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Lactobacillus kefiri, a probiotic strain found in kefir, has some scientific evidence supporting its use for constipation in children, though the evidence base is limited and not yet robust. Small clinical studies and pilot trials have investigated the effects of kefir or L. kefiri supplementation on bowel movements in children with functional constipation. For example, a randomized controlled trial published in Pediatric Research (2017) evaluated kefir fermented milk containing L. kefiri in children with constipation and reported a significant increase in stool frequency compared to baseline. Some hypothesized mechanisms include modulation of gut microbiota composition, production of short-chain fatty acids, and improved intestinal motility.

Despite these encouraging findings, the overall quality and quantity of evidence remain low. Most studies to date are small, have methodological limitations, and often use kefir (which contains multiple probiotic species) rather than isolated L. kefiri, making it difficult to attribute benefits solely to this strain. Systematic reviews and meta-analyses of probiotics for pediatric constipation typically note that while certain probiotic strains may offer mild benefit, the evidence is inconsistent and does not allow for strong recommendations of any specific strain, including L. kefiri.

In summary, there is preliminary scientific evidence suggesting a potential benefit of L. kefiri for childhood constipation, but larger, high-quality trials are needed to confirm efficacy and safety.
