ImproBiome (ImproBiome Prebiotics Formula) is a prebiotic fiber dietary supplement from PureHealth Research. It contains four soluble fibers — xylooligosaccharides, chicory root inulin, Jerusalem artichoke inulin and apple pectin — that feed the beneficial bacteria in your gut microbiome.*

As a dietary supplement, adults take three vegetarian capsules daily, ideally with 6–8 fl oz of water, or as directed by a healthcare professional. Each bottle contains 90 capsules — a 30-day supply.

Prebiotics work gradually as your microbiome adjusts. Many people describe the first changes — easier bathroom habits and less bloating — within two to four weeks of consistent daily use. Individual results vary, which is why the long guarantee is useful.*

Prebiotic fibers are fermented by gut bacteria into short-chain fatty acids, which are among the natural signals involved in the GLP-1 pathway. ImproBiome supports that gut environment. It is a supplement, not a medication, and it is not affiliated with or a substitute for any GLP-1 drug.*

No — it's a prebiotic. Probiotics add live bacteria; ImproBiome provides the fibers that feed the good bacteria you already have. The two are complementary but different.

Any support works indirectly — through appetite comfort, better digestion and regularity — alongside diet and activity. ImproBiome is not a weight-loss drug and won't produce results on its own. Individual results vary.*

Prebiotic fibers are generally well tolerated. Because they feed gut bacteria, some people notice temporary gas or bloating when starting, which usually settles within a week or two. Take with plenty of water. If you have a digestive condition or fiber sensitivity, check with your doctor first.

ImproBiome is designed for daily, ongoing use, and dietary fiber is broadly beneficial for gut health. It complements — but doesn't replace — a varied, fiber-rich diet.
