What is the Origin of Prebiotic Support?

The term originated in the field of nutritional science and microbiology, distinguishing these substrates from probiotics (the live microorganisms themselves). Prebiotic signifies "before life," indicating the substance that feeds the beneficial bacteria. The clinical relevance has expanded with the understanding of the gut-brain and gut-endocrine axes.

What is the Mechanism of Prebiotic Support?

Prebiotic fibers, typically certain types of resistant starch and oligosaccharides, pass undigested through the upper gastrointestinal tract and reach the colon. There, they are selectively fermented by commensal bacteria, leading to the production of short-chain fatty acids (SCFAs) like butyrate, acetate, and propionate. These SCFAs serve as energy sources for colonocytes, modulate the immune system, and can influence host metabolism and hormone signaling, such as insulin sensitivity and satiety regulation.

Prebiotic Support

Meaning

Prebiotic support refers to the clinical or dietary practice of providing non-digestible compounds that selectively stimulate the growth and activity of beneficial microorganisms already residing in the gut. These substrates are essential for maintaining a healthy and diverse gut microbiome, which is intrinsically linked to hormonal balance, immune function, and overall metabolic health. It is a critical component of a comprehensive wellness strategy.
