Probiotics cut NEC risk 20% in extremely preterm infants — but the evidence is rated low to very low certainty

This is one of the first meta-analyses to look at this specific probiotic strain in this fragile population, so the result is intriguing but far from settled — the low-quality evidence means the true benefit could be smaller or even absent.

A meta-analysis of 14 studies found that giving Bifidobacterium breve HA-129 to extremely preterm babies was linked to a 20% lower risk of necrotising enterocolitis, a severe gut infection. However, the same analysis showed no significant improvement in feeding tolerance, and the overall quality of the evidence was low to very low — so the finding should be interpreted with caution, not as a proven solution.

Where this fits in the evidence

This is among the first studies we've indexed on Bifidobacterium breve HA-129 for Reduced Necrotising Enterocolitis — treat it as an early signal until more research accumulates.
