Types of Gut Microbiome Supplements
Probiotics
Probiotics are live bacteria and yeasts from the same groups that make up a healthy gut microbiome. On the label you’ll see a number followed by CFU, short for colony-forming units. It tells you how many live bacteria are in one serving, and it usually runs in the billions. Spore-based probiotics use bacteria that wrap themselves in a tough outer shell. The shell protects them from stomach acid, and you can keep the bottle in a cupboard instead of the fridge.
Prebiotics
Prebiotics are a type of fiber your body can’t break down on its own. They travel down to the large intestine, where gut bacteria eat them. Inulin is one of the most common prebiotics. It comes from chicory root, a plant in the dandelion family. GOS (galactooligosaccharides) is a fiber made from milk sugar. Polyphenols are natural plant compounds found in berries and green tea, and gut bacteria feed on them too.
Postbiotics
Postbiotics are compounds your gut bacteria make after they digest fiber. The main one is butyrate, a fatty acid that the cells lining your colon burn for fuel. If you don’t eat much fiber, your bacteria make less of it, and a butyrate supplement is a direct way to get it.
Synbiotics
A synbiotic is a product containing a probiotic plus a prebiotic, in the form of a fiber that the bacteria can eat. Some formulas are 3-in-1, meaning they contain not only a probiotic and a prebiotic but also a postbiotic. Some products are manufactured in a single capsule.
