What is the Origin of Probiotic Use?

The concept originated with the early 20th-century work of Elie Metchnikoff, who theorized that the consumption of fermented milk products containing beneficial bacteria could promote longevity. The modern clinical application is rooted in extensive molecular biology research that has elucidated the complex, bidirectional signaling pathways between the gut microbiome and host physiology, particularly the enteroendocrine system. This research validated the link between microbial ecology and systemic health.

What is the Mechanism of Probiotic Use?

The mechanism of action is multifaceted, including competitive exclusion of pathogenic organisms, production of beneficial short-chain fatty acids (SCFAs) like butyrate, and direct signaling to the intestinal epithelial and immune cells. By stabilizing the gut barrier and influencing the enterohepatic circulation of hormones, probiotic supplementation provides a non-pharmacological lever to support systemic hormonal balance and improve the host's metabolic phenotype. This intervention targets the gut as a key endocrine modulator.

Probiotic Use

Meaning

Probiotic use involves the therapeutic administration of live microorganisms, primarily specific strains of bacteria and yeasts, intended to confer a health benefit on the host by transiently or permanently modulating the composition and function of the gut microbiota. In the context of hormonal and metabolic health, these interventions are employed to influence the gut-brain-endocrine axis, potentially improving nutrient absorption, reducing systemic inflammation, and aiding in the metabolism of endogenous and exogenous hormones, such as estrogen and thyroid compounds. The goal is to enhance gut barrier integrity and diversify the microbial ecosystem.
