Bifidobacterium lactis is a probiotic strain that has been investigated for its potential to alleviate constipation in children. Scientific evidence, including randomized controlled trials (RCTs), supports its use in this context, although results are somewhat mixed and the overall strength of evidence is moderate.

Several studies have found that supplementation with B. lactis can increase stool frequency and improve stool consistency in constipated children. For example, a notable RCT published in Pediatrics (2010) showed that children receiving B. lactis had significantly more frequent bowel movements compared to placebo. Other studies, such as those published in the World Journal of Gastroenterology and European Journal of Pediatrics, have also reported improvements in stool frequency, consistency, and decreased abdominal pain.

The proposed mechanisms include modulation of gut microbiota, enhancement of intestinal motility, and production of short-chain fatty acids that stimulate bowel movements. B. lactis is generally well-tolerated with minimal side effects reported in pediatric populations.

However, not all studies have demonstrated significant benefits, and some meta-analyses suggest that while B. lactis may help, its effect size is modest and may vary depending on dosage, duration, and individual patient factors. Further large-scale, high-quality RCTs are needed to strengthen the evidence base.

In summary, there is moderate scientific support for the use of Bifidobacterium lactis in the management of constipation in children, but it should be considered as part of a broader management strategy.
