probiotics
Probiotics are beneficial microorganisms—such as bacteria and fungi—that enhance the health and development of their plant hosts through colonization of tissues and soil environments. These plant-associated microbes improve nutrient uptake, strengthen disease resistance, and promote growth through mutualistic relationships with their plant partners. Harnessing these microbial communities represents an important frontier in plant biology research for developing sustainable agricultural practices and increasing crop productivity.

A comprehensive review examines how prebiotics, probiotics, and postbiotics affect maternal and fetal health during pregnancy, detailing their roles across gut, immune, vaginal, placental, and breast milk systems — and outlining safety and quality standards for each class.
Prebiotics reshape short-chain fatty acid and bile acid pools in the gut, tighten epithelial junctions, and reduce microbial translocation and endotoxemia, lowering vascular strain during pregnancy.
Vaginal lactobacilli maintain acidity, suppress harmful microbes, and may reduce colonization risk for pathogens — a key safety factor for maternal and fetal outcomes.
Safety profiles differ significantly by class: prebiotics are generally well tolerated with dose-dependent GI side effects, while probiotics require strain-level validation and contaminant-free production, and postbiotics need verified inactivation and structural characterization.
