Fructooligosaccharides (FOS)
Fructooligosaccharides (FOS) are plant-based prebiotic fibers found in a variety of fruits, vegetables, and other plants. The human body can't digest them, but they serve as food for beneficial gut bacteria and help maintain a healthy gut microbiota.

Natural sources of FOS
FOS occurs naturally in chicory, artichokes, onions, garlic, leeks, asparagus, and some fruits. In supplements and functional foods, it's typically derived from plant sources and used in powders, capsules, soluble blends, and other products.
Recommended FOS dosage
How much FOS you need can vary depending on your overall fiber intake and your digestive system's individual sensitivity. Most people consume around 2-10 g of FOS per day. It's best to find the right amount for you individually, based on how your body responds and your personal needs.
Possible side effects of FOS and interactions with medications
FOS is generally well tolerated, but starting with larger amounts may cause bloating, gas, or other temporary digestive changes in some people. For this reason, it's best to introduce FOS into your diet gradually. If you have a chronic digestive condition or take specialized medication for bowel function, talk to your doctor before use.
