Neonatal microbiomes often lack the metabolic versatility to process both maternal and solid food carbohydrate sources simultaneously. Establishing early microbial dominance prevents pathogenic infiltration and supports developmental nutrition.

Insufficient secretory immunoglobulin production and disrupted gut-brain axis signaling. Restoring these biological functions mitigates systemic inflammation and neurological symptoms.

Low natural growth rates of Faecalibacterium prausnitzii limit its therapeutic efficacy in the gut. Overcoming this growth bottleneck increases the production of anti-inflammatory metabolites and proteins like Serpin.
