Fructooligosaccharides

Fructooligosaccharides (FOS) are a type of prebiotic carbohydrate found naturally in many plants like garlic, onions, and bananas. They are short chains of sugar molecules that human digestion cannot fully break down, so they reach the gut intact. In the intestines, FOS serve as food for beneficial bacteria, helping to promote a healthy gut microbiome. This can improve digestion, boost immune function, and support overall well-being. Because they are low in calories and promote gut health, FOS are often added to foods and supplements aiming to enhance digestive health.
