What to take to improve gut health?
Improving gut health involves a combination of targeted nutrition, thoughtful supplementation, and lifestyle adjustments informed by reliable testing. The gut microbiome—trillions of microbes in the intestine—affects digestion, immune function, inflammation, and even mood. Rather than relying on one-size-fits-all advice, data-driven strategies such as microbiome analysis can guide which interventions are most appropriate for an individual.
Use microbiome testing to personalize choices
Stool-based microbiome tests that use DNA sequencing offer a window into which bacterial groups are abundant or deficient. Results often include diversity scores, markers of inflammation, and indications of how well your gut processes specific foods. A personalized report can identify deficiencies in beneficial strains (for example, Bifidobacterium or Akkermansia) and suggest targeted interventions. For an overview of practical guidance based on results, see this guide on what to take to improve gut health.
Key nutritional supports: probiotics, prebiotics, and foods
Probiotics are strain-specific: choosing a product based on identified deficits is more effective than a random selection. Commonly researched strains include Lactobacillus rhamnosus, Bifidobacterium longum, and the yeast Saccharomyces boulardii. Prebiotics—non-digestible fibers such as inulin, resistant starch, and fructooligosaccharides—feed beneficial microbes and enhance short-chain fatty acid production. Whole-food choices that support microbial diversity include high-fiber vegetables, whole grains, fermented foods, and polyphenol-rich fruits like berries.
Digestive enzymes and targeted supports
When digestion is impaired, enzyme supplements (protease, amylase, lipase, lactase) can reduce fermentation of undigested food in the colon and relieve symptoms such as bloating. Other specialized supports—betaine HCl for low stomach acid, bile salts for fat digestion, or DPP-IV for gluten sensitivity—may be appropriate depending on symptom pattern and test findings. Pairing enzyme support with food and probiotic strategies helps improve nutrient absorption and microbial balance.
Lifestyle factors that matter
Sleep, stress management, and regular physical activity strongly influence microbiome composition. Poor sleep and chronic stress are associated with reduced diversity and increased intestinal permeability, while moderate exercise promotes beneficial genera. Hydration, mindful eating (slow chewing, regular meal timing), and limiting chronic use of irritants such as alcohol or frequent NSAIDs also protect the gut barrier.
Learn from common pitfalls and further reading
Avoid common testing and interpretation mistakes by reviewing resources on preparation and result interpretation; practical lists on common microbiome test mistakes and a shorter checklist at top mistakes to avoid when taking a microbiome test can be helpful. For questions about coverage and logistics, see guidance on health insurance and microbiome testing.
When used together—individualized test data, targeted supplements (probiotics, prebiotics, enzymes), gut-supportive foods, and consistent lifestyle habits—these approaches form an evidence-aligned framework to restore and sustain intestinal health.
