Recently, probiotics have been studied as a potential treatment for IBS and other digestive disorders. In addition, the potential of probiotics for enhancing another aspect of health, specifically cognitive function, is currently being investigated by some scientists. New evidence suggests that the mix of bacteria in one's digestive tract can affect one's brain function and emotional state. In addition, psychiatric disorders like depression have been linked to a microbiome imbalance. These studies have supported the idea that the gut microbiome can affect factors such as cognition, memory, and mood when it is manipulated via probiotic supplementation.
