Human bodies are home to a lot of microorganisms, especially body parts like the mouth, skin, and digestive tract. These parts are exposed to external factors. These microorganisms are called commensal microbes and are largely interdependent with the human population.
Probiotics play a vital role in the health of our digestive systems. They are living microorganisms that are intended to deliver healthy bacteria to our large intestine, to colonize and flourish. This is important because our bodies are made up of 10-20x more bacteria than cells.
Probiotics are live organisms such as bacteria or yeast that can be used to treat various intestinal problems and to prevent the intestinal lining from getting damaged. These are available as probiotic supplements and foods.
According to various medical studies, probiotics are also extremely beneficial in maintaining a strong immune system. Researchers claim that people with remarkably good immune system can sometimes suffer from various autoimmune and allergic diseases, possibly because their immune system is not adequately challenged by pathogenic organisms.
Probiotic supplements can be availed in a number of forms like drinks, powders, tablets, etc. They are also available in the form of fortified foods like yoghurt. The most significant and common types of bacteria used for the production of probiotics are Saccharomyces boulardii and Bifidobacterium lactobacillus.
