Probiotics are often called "good" or "helpful" bacteria because they help keep your gut healthy. Probiotics are live bacteria and yeasts that are good for you, especially your digestive system. You constantly have both good and bad bacteria in your body. When you get an infection, there’s more bad bacteria, knocking your system out of balance. Good bacteria helps eliminate extra bad bacteria, returning the balance. Probiotic supplements are a way to add good bacteria to your body.
Probiotics provide all sorts of powerful benefits for your body and brain. They may improve digestive health, reduce depression and promote heart health. Some evidence suggests they may even give you better-looking skin. Further potential benefits of probiotics have been seen in the treatment or prevention of diarrhoea, irritable bowel syndrome, Crohn's disease, vaginal infections, urinary tract infections, recurrence of bladder cancer and eczema in children.
