Ginger root has anti-inflammatory, antitumor, and antiulcer properties – factors that can all support gut health. And along with its nausea relief benefit, some data shows that taking it consistently can inhibit the growth of h. pylori, which is a bacteria that can infect your stomach and may increase your risk of developing stomach ulcers or stomach cancer.

Probiotics

Certain strains of probiotics—or live bacteria—may help support gut health by helping keep the "good" bacterial diversity and balance up-to-par. Some data shows that having an imbalance of "good" and "bad" bacteria is linked to several gastrointestinal diseases, and taking probiotics has been shown to help people have more regular bowel movements.

7 Probiotic Foods Scientifically Linked to Better Health

Prebiotics

While probiotics are an important part of the gut health story, they aren't the only key factor in having a healthy gut microbiome. Prebiotics—or indigestible fibers—act as fuel for probiotics, which can help them thrive in the gut. Prebiotics are also able to affect the pH of the gut, which can, in turn, affect which bacteria will thrive in that environment, as certain "bad" bacteria don't thrive in an acidic environment.

Thorne Prebiotic+ not only contains prebiotic fiber, but it also contains other "bonuses" like green tea extract and pomegranate extract for additional health benefits.

Postbiotics

Now you know about prebiotics and probiotics, but what about postbiotics? The International Scientific Association for Probiotics and Prebiotics (ISAPP) defines a postbiotic as a "preparation of inanimate microorganisms and/or their components that confers a health benefit on the host." Overall, postbiotics may offer some unique benefits when focusing on the gut microbiome, but more data is needed before we can know for sure.

Ritual Synbiotic + contains prebiotics, probiotics, and postbiotics for the gut health-supporting trifecta that may help people who are on their gut health journey.

L-glutamine

L-glutamine is a non-essential amino acid that becomes essential (AKA your body depends on you to consume enough to meet its needs) during periods of stress. This amino acid is an important part of intestinal cells, and it may help enhance the function of cells in the small intestine. Some data also suggests that it can positively support a healthy balance of gut microbiome, and it helps manage inflammation that may occur in the gut.

Life Extension L-Glutamine provides 500 milligrams of this important amino acid.

12 Easy Ways To Get Rid of Bloating

Digestive enzymes

Your body requires certain enzymes to digest food. These digestive enzymes help break down the macronutrients that we eat, and without them, you may experience digestive challenges, such as diarrhea or excessive gas.

Most people produce enough digestive enzymes. But if you do not produce enough, you may benefit from taking a digestive enzyme supplement, like Pure Encapsulations Digestive Enzymes.

Lactase

If you have lactose intolerance, you already know all about the bloating and diarrhea that you can often experience after you drink dairy. People with lactose intolerance do not produce enough of the lactase enzyme the body needs to break down the lactose sugar that is naturally found in many dairy foods. But, having lactose intolerance doesn't mean that you have to give up your beloved glass of milk that you enjoy alongside some Oreo cookies. Those with lactose intolerance can opt for lactose-free milk, or they can supply their body with the lactase enzyme via supplementation.

Lactaid is one very popular lactase supplement that can help people manage their symptoms if they have lactose intolerance and they can't do without that delicious scoop of ice cream or creamy cup of cottage cheese.
