Digestive disorders are conditions that affect the gastrointestinal tract, impairing digestion, nutrient absorption, or waste elimination. The digestive disorders are increasing due to poor dietary habits, as processed and low-fiber foods disrupt gut health and impair normal digestion. Over-the-counter (OTC) probiotic supplements support digestive health by restoring and maintaining a healthy gut microbiome, making them beneficial for individuals with digestive disorders. They improve nutrient absorption and reduce symptoms such as bloating, constipation, and diarrhea, enhancing overall gastrointestinal well-being. For instance, in December 2023, according to the IBD Registry, a UK-based non-profit organization, the number of people with inflammatory bowel disease (a chronic digestive disorder causing inflammation in the gut) reached 5,300 in 2023, an increase of over 3,000 from 2022.
