The human gastrointestinal system is a complex micro-ecosystem with delicate balances between the organisms that constitute it (approximately 500). Various factors, such as improper diet, stress, various diseases, toxic substances and medications, but especially the use of antibiotics, can disrupt this fragile balance, resulting in the disproportionate growth of harmful microorganisms at the expense of beneficial ones. This pathological condition, also known as dysbiosis, often leads to dysfunctions and diseases, including: Weakening of the immune system Diarrhea and other intestinal disorders Food allergies and intolerances Bad breath Chronic vaginal yeast infections in women Increasing the population of beneficial bacteria and restoring disturbances.
