Fructo-oligosaccharides (FOS) are short chains of fructose molecules that are classified as dietary fibers. They are found naturally in some plant-based foods, such as onions, garlic, and chicory root, and can also be produced through the fermentation of sugars. FOS are not digestible by the human body and pass through the digestive system largely unchanged, making them a type of prebiotic fiber.

Prebiotics are non-digestible substances that promote the growth of beneficial bacteria in the gut. FOS are considered prebiotics because they are fermented by the bacteria in the colon, which can help to increase the population of beneficial bacteria and improve the balance of the gut microbiome. This can have various health benefits, including improved digestion and regularity, a strengthened immune system, and a reduced risk of certain diseases.
