In normal physiological conditions, our intestine is densely colonized by billions of microorganisms that make up our bacterial flora, whose fundamental function is to counteract the spread of pathogenic bacteria to which we commonly come into contact with food, to favor the absorption of nutrients and to support the complex of the immune system, as well as having significant influence on the health of our psyche. It is therefore essential to have a balanced intestinal environment that allows a predominance of good bacteria controlling pathogens for our general health. This is why the use of probiotics is becoming increasingly widespread, within certain foods and supplements that favor the life of the microbiota. In spite of marketing, it is not easy to guarantee an effective intake of probiotics through food alone, both in terms of quality and quantity. The extreme use of refining methods in the food industry and food conservation does not allow the integrity and vitality of these bacteria. This also applies to the vast market of probiotic supplements, that is why it is important to make informed decisions. Bacillus coagulans, also known as “Lactobacillus Sporogenes”, is a beneficial bacterium that produces spores. These are dormant bacilli that remain in their protective shield awaiting ideal external conditions to grow and reproduce. These particular probiotics can be kept intact in their potential form at room temperature. Thanks to their natural capsule protecting them from heat, acid pH of the stomach and the attack of gastric juices, they safely arrive in the intestine, where they can germinate, reproduce and colonize within an hour from their intake, enriching the bacterial flora with new energies and defenses. Most probiotics are not effective because they are thermolabile or do not resist the pH levels of our stomach, so we often take probiotics that are dead and have no effects. Bacillus coagulans can resist gastric acid and intestinal basic Ph, that’s why it can be effective in areas where most of the other probiotics cannot. They exert their precious support activity in cases of diarrhea, after antibiotic-based drug therapy, in case of colitis, diverticulitis and to regenerate the immune system. The spores of Bacillus coagulans also have a high adhesion capacity to the gastrointestinal mucosa, have inhibition capacity against other weakened bacteria, and relieve the symptoms of various pathologies including acute catarrhal enteritis, diarrhea, constipation, intestinal fermentation, neonatal diarrhea, nonspecific vaginitis, inflammatory bowel disorders, etc… Bacillus coagulans act throughout the gastrointestinal tract creating an environment conducive to the maintenance and growth of the other beneficial strains. It is also resistant to most antibiotics, making it possible to take them during antibiotic therapies to counteract typical side effects on the bacterial flora.
