Gut health is a cornerstone of overall health. The digestive tract is home to 70 to 80 percent of the body’s immune cells and produces more than 90 percent of the body’s serotonin. A balanced microbiome, regular bowel movements, and an intact intestinal lining are essential for digestion, immunity, and nervous system balance. Explore our line of probiotic supplements.
What is gut health?
Gut health encompasses three complementary dimensions: digestive function (bowel movements, nutrient absorption), the microbiome (balance of 100,000 billion gut bacteria), andthe integrity of the mucosal lining (permeability of the intestinal barrier). These three aspects are interdependent—an imbalance in one affects the other two. Daily digestive comfort is a direct reflection of this overall balance.
Microbiome and Probiotics: What Role Do They Play?
The gut microbiome is an ecosystem of 100,000 billion microorganisms that play a role in digestion, immunity, and the production of neurotransmitters.
- Probiotics are beneficial live bacteria that strengthen the microbiome—Lactobacillus, Bifidobacterium
- Prebiotics (non-digestible fibers: inulin, FOS) nourish these good bacteria
- Glutamine is the preferred amino acid of enterocytes—it maintains the integrity of the intestinal barrier
- Omega-3 EPA+DHA support the balance of the intestinal immune response
- Zinc contributes to the integrity of the tight junctions in the intestinal mucosa
Signs of an intestinal imbalance?
Several signs indicate that the microbiome or the intestinal mucosa require attention.
- Functional disorders: bloating, gas, recurrent constipation, or diarrhea—see our gut and digestion line
- Digestive disturbances: slow or accelerated bowel movements
- Persistent, unexplained fatigue—linked to poor intestinal absorption of micronutrients
- Increased susceptibility to ENT and respiratory infections—a sign of compromised gut immunity
- Digestive reactions to foods: see our page on food intolerances
- If symptoms are persistent or severe, consult a gastroenterologist
Gut-Brain Axis: What’s the Connection?
The gut-brain axis refers to the bidirectional communication network between the enteric nervous system (digestive tract) and the brain.
- 90% of the body’s serotonin is produced in the gut—the microbiome directly influences the availability of this neuromodulator
- The vagus nerve transmits information from the gut to the brain in real time—the microbiome and mood are closely linked
- Dysbiosis (an imbalance in the microbiome) can affect stress management and sleep quality
- Psychobiotic probiotics (Lactobacillus rhamnosus, L. helveticus, B. longum) are the subject of active research on the gut-brain axis
Diet and Gut Health?
Diet is the primary factor in maintaining the balance of the gut microbiome.
- A variety of fibers (soluble and insoluble): legumes, vegetables, fruits, whole grains—microbial diversity correlates with dietary diversity
- Fermented foods: yogurt, kefir, kimchi, sauerkraut—direct source of live lactic acid bacteria
- Reduce ultra-processed foods, alcohol, and added sugars—documented disruptors of the microbiome
- Adequate hydration: Water maintains the fluidity of intestinal contents and the health of the mucosal lining
- For people with food intolerances (lactose, gluten): targeted elimination
Exercise and managing gut-related stress?
Two lifestyle factors that are often underestimated but significantly effective for gut health.
- Moderate, regular physical activity: stimulates intestinal motility, prevents constipation, and improves microbial diversity
- Chronic stress via the HPA axis: alters intestinal permeability and microbiome composition—manage through cardiac coherence, yoga, and meditation
- Adequate sleep: Sleep deprivation rapidly disrupts the balance of the microbiome
- L-glutamine can support mucosal integrity during periods of intense stress (sports, illness, chronic stress)
- If symptoms persist after lifestyle changes: a medical consultation is recommended
