Prebiotic

Ingredients

Prebiotics are substrates that are selectively utilized by microorganisms in the body and provide a health benefit. Many dietary prebiotics are non-digestible carbohydrates and fibers, including inulin, fructooligosaccharides (FOS), galactooligosaccharides (GOS), resistant starch, and certain other fermentable fibers. The exact ingredient, source, amount, and formulation vary between supplements.

Prebiotics are substances that are selectively utilized by microorganisms in the body and provide a health benefit. In nutrition, prebiotics are commonly associated with certain dietary fibers and non-digestible carbohydrates that can be utilized by beneficial microorganisms in the gastrointestinal tract.

Common prebiotic ingredients include inulin, fructooligosaccharides (FOS), galactooligosaccharides (GOS), resistant starch, and certain other fermentable fibers. Naturally occurring sources include foods such as chicory root, onions, garlic, asparagus, legumes, and some whole grains, although the amount and type of prebiotic compounds vary among foods.

Prebiotics can be fermented by microorganisms in the large intestine. Their fermentation may produce short-chain fatty acids and other metabolites, which are part of ongoing research into the relationship between dietary fiber, gut microbiota, and gastrointestinal health. (pubmed.ncbi.nlm.nih.gov)

In dietary supplements, prebiotics may be provided as powders, capsules, tablets, gummies, or as part of synbiotic formulations combining prebiotics with probiotics. The specific type and amount of fiber can affect digestive tolerance and individual response.

Because “prebiotic” describes a functional characteristic rather than one single ingredient, not every fiber or fermentable carbohydrate automatically qualifies as a prebiotic. Consumers should check the specific ingredient, amount per serving, and manufacturer's product information.
