Inulin Prebiotic Fiber
by Inulin / chicory root · Highly fermentable prebiotic
Strong prebiotic but highly fermentable — a common cause of exactly the gas and bloating GLP-1 users are already fighting. Usually the wrong pick here.
Inulin is everywhere, added to bars, shakes, and 'gut health' powders, because it is a strong prebiotic. That is also why it is usually the wrong choice on a GLP-1: it is highly fermentable and one of the most common causes of gas, bloating, and cramping, exactly the symptoms GLP-1 users are already fighting. If a product you already use lists inulin or chicory root high on the label and you feel gassier than expected, that is a likely culprit. Listed last here on purpose.
GLP-1 medications slow how fast the gut moves, and you're taking in less of everything, fiber and water included. That combination is why constipation is one of the most common early side effects. The catch: the wrong fiber can make things worse. Highly fermentable types feed gas production in a gut that is already bloated and uncomfortable.
Start at about half the label dose and build up over a week or two, and treat water as non-negotiable, because fiber works by holding water in the stool and taking it dry can backfire. Non-fermenting fibers tend to be the most comfortable starting point. If constipation doesn't ease with fiber, fluids, and magnesium over a couple of weeks, that is worth a call to your prescriber.
