Probiotics are live bacteria and yeasts that are good for your health, especially your digestive system. We usually think of bacteria as something that causes diseases. But your body is full of bacteria, both good and bad. Probiotics are often called "good" or "helpful" bacteria because they help keep your gut healthy.
When you lose "good" bacteria in your body (like after you take antibiotics, for example), probiotics can help replace them. They can lower the amount of "bad" bacteria in your system that can cause infections or other problems. They can help balance your "good" and "bad" bacteria to keep your body working like it should.
Probiotics are foods or supplements that contain these friendly bacteria, and are supposed to help colonise our guts with health-boosting microorganisms.There are actually dozens of different probiotic bacteria that have been shown to have health benefits. The most common groups include Lactobacillus and Bifidobacterium. Then there are many different species within each group, and each species has many strains.
