The human gut is home to approximately 70% of the body's immune cells, which play a crucial role in producing immunologically active substances and initiating the majority of immune responses. This is supported by scientific research, including studies from the National Institutes of Health (NIH) and the European Food Safety Authority (EFSA), which highlight the gut's central role in immune function. A balanced gut microbiome, as supported by probiotics like those in LYLBIOTIC, contributes to normal immune system operation as part of a healthy lifestyle, in line with EU Regulation (EC) No 1924/2006 on nutrition and health claims. However, LYLBIOTIC is a dietary supplement and is not intended to diagnose, treat, or prevent any disease.

The gut microbiome refers to the trillions of microorganisms, including bacteria, fungi, and viruses, that reside in the human gastrointestinal tract. These microbes help with digestion, nutrient absorption, and immune regulation, influencing overall health. According to scientific consensus from bodies like the World Health Organization (WHO) and EFSA, a diverse and balanced microbiome is essential for maintaining normal digestive and immune functions. LYLBIOTIC supports this balance through its 9 clinically studied bacterial strains and prebiotic inulin, aligning with EU guidelines for dietary supplements that promote general well-being without making therapeutic claims.

LYLBIOTIC is classified as a synbiotic because it combines probiotics (live beneficial bacteria) with prebiotics (non-digestible fibers like inulin that feed these bacteria). This synergistic approach enhances the survival and activity of the probiotics in the gut, as defined by the International Scientific Association for Probiotics and Prebiotics (ISAPP). Clinical studies, such as those published in the Journal of Clinical Gastroenterology, demonstrate that synbiotics provide greater benefits for gut health than probiotics alone. Under EU regulations, synbiotics like LYLBIOTIC can claim to support a healthy gut microbiome as part of a varied diet, but they are not medicines and do not treat specific conditions.

LYLBIOTIC includes 9 diverse, clinically studied bacterial strains (B. lactis, B. infantis, B. longum, L. reuteri, L. casei, L. gasseri, L. plantarum, L. rhamnosus, and S. boulardii) because research shows that bacterial diversity enhances efficacy in supporting gut health. Studies from EFSA-approved reviews and meta-analyses in journals like Gut Microbes indicate that multi-strain probiotics provide broader benefits for microbiome balance, digestion, and immune support compared to single-strain products. This aligns with EU health claim regulations, allowing statements on contributing to normal gut function in healthy individuals, while emphasizing that LYLBIOTIC complements—not replaces—a balanced lifestyle.

The bacteria in LYLBIOTIC are protected by patented DRcaps® technology, a plant-based delayed-release capsule that shields them from stomach acid and environmental factors. This ensures the 34 billion live CFUs reach the intestines intact, where they activate for optimal efficacy. Scientific validation from clinical trials, including those by Capsugel (the DRcaps® developer), shows up to 85% higher viability compared to standard capsules. EFSA recognizes such enteric protection in probiotic formulations, allowing claims for improved delivery that support normal microbiome function under EU dietary supplement rules, without implying treatment of any health issues.

Colony-forming units (CFUs) are a standard scientific measure used to quantify the number of viable, live bacteria in a probiotic product that can form colonies and reproduce in the gut. In LYLBIOTIC, each capsule delivers 34 billion CFUs from 9 strains, ensuring high potency as confirmed by laboratory testing. According to ISAPP guidelines and EFSA evaluations, higher CFU counts and strain diversity correlate with better support for gut health in clinical studies. EU regulations require accurate labeling of CFUs at the end of shelf life, and LYLBIOTIC meets these standards to promote microbiome balance as a dietary supplement, not as a medical intervention.
