Gut flora, a complex ecosystem of up to 100 trillion microbes, plays a vital role in digestion, nutrient synthesis, and the immune system, with 83% of immunity located in the gut wall. Dysbiosis occurs when gut flora is imbalanced, leading to health issues like leaky gut syndrome and chronic diseases, which can be exacerbated by factors such as antibiotics, poor diet, and stress. Probiotics, particularly Probiotic 11, containing multiple strains of beneficial bacteria, can help restore gut health and are beneficial in various clinical settings.
