Next year, the worldwide market for probiotics will reach $69.3 billion. This isn’t just a diet fad; probiotics are proven treatments for inflammatory bowel disease, urinary tract infections, and even obesity. They can even reduce symptoms of depression and stress!
How is this possible? Probiotics are major supporters of the microbiome active in the human gut. A normal human has up to 100 trillion bacteria living in their digestive tract, an area that accounts for between 70% and 80% of immune cells and generating 95% of the body’s serotonin supply. Serotonin is a major mood influencing hormone, which helps explain why gut issues can affect mental health as well.
Probiotics are live bacteria found in certain foods or supplements that colonize the digestive tract. While people may associate bacteria with disease, the types of bacteria found in most yogurt, cheese, or kimchi are natural and beneficial to human health.
