Top 5 Gut-Healing Supplements Doctors Swear By for Better Digestion and Immunity

Your gut does a lot more than just digest food—it’s the command center for your overall health. In fact, about 80% of your immune system lives in your gut, where trillions of helpful microbes keep things running smoothly. These microbes help with digestion, nutrient absorption, blood sugar regulation, weight control, and even protection against chronic diseases.

According to the American Gastroenterological Association, an estimated 60–70 million Americans struggle with gastrointestinal (GI) conditions linked to poor gut health. While healthy eating and lifestyle changes are key, gut-supporting supplements can make a real difference in keeping your digestive system balanced and strong.

Here are five of the best supplements that can help restore your gut and keep your digestive system happy.

What Does “Gut Health” Really Mean?

When people talk about “gut health,” they’re referring to a mix of important factors working together. A healthy gut means:

• A balanced microbiome (the good bacteria in your intestines)
• A strong intestinal lining that keeps harmful substances out
• Smooth digestion and regular bowel movements
• Low inflammation in the digestive tract
• Healthy production of short-chain fatty acids, which nourish the cells of your colon

In short, a healthy gut keeps your body in harmony from the inside out.

1. Probiotics: The Good Bacteria Your Gut Loves

Probiotics are live microorganisms—often called good bacteria—that strengthen the natural microbiome in your large intestine. These supplements, available in capsules, liquids, or powders, support digestion, reduce bloating, and help maintain a healthy immune response.

They’re especially useful after taking antibiotics or during periods of digestive upset, when your body needs help restoring balance.

2. Psyllium Husk: The Fiber That Keeps Things Moving

Psyllium husk comes from the seeds of the Plantago ovata plant and is one of the best natural sources of fiber. It soaks up water in your digestive tract, forming a gel-like texture that makes bowel movements smoother and more regular.

A study in Food Bioscience found that psyllium helps increase short-chain fatty acids, reduce gut inflammation, repair the intestinal barrier, and promote beneficial bacteria.

It’s usually taken as a powder mixed with water or smoothies—just be sure to drink plenty of fluids with it.

3. Peppermint Oil: Nature’s Soothing Digestive Aid

Peppermint oil, extracted from the peppermint plant, is a gentle but powerful way to support digestion. It helps relax muscles in the stomach, esophagus, and intestines, reducing cramps and discomfort.

According to research from the National Library of Medicine, peppermint oil can help manage symptoms of irritable bowel syndrome (IBS) and abdominal pain.

It’s available in capsules, soft gels, and even added to teas or snacks—though it should always be properly diluted before consumption.

4. L-Glutamine: The Gut-Healing Amino Acid

L-Glutamine is an amino acid that plays a major role in maintaining and repairing your gut lining. It helps prevent bacterial leakage into the bloodstream, supports healthy digestion, and may assist with managing obesity and constipation, according to the International Journal of Molecular Sciences.

While there isn’t a single recommended dose for everyone, a study in Nutrients found that 0.9 grams per kilogram of fat-free body mass is generally well-tolerated.

You can take it as a capsule or powder, often mixed with water or juice.

5. Ginger: The All-Natural Digestive Booster

Known for its soothing effects, ginger is a time-tested remedy for nausea, bloating, and inflammation. Made from the root of the ginger plant, it’s available as a powder, capsule, or tea.

According to research in the Cureus Journal of Medical Science, ginger root powder may help reduce symptoms like feeling full too quickly or abdominal pain. It also promotes digestion by increasing saliva and bile production, which helps your body break down food more efficiently.
