What are probiotics?

Probiotics are live bacteria and microorganisms that naturally live in your body. There are two types of bacteria- good and bad. Probiotics represent the good bacteria (main type of bacteria are- Lactobacillus and Bifidobacterium) and yeasts (most common type is Saccharomyces boulardii). 

There are several scientific pieces of evidence suggesting that you can treat and even prevent some illnesses with foods and supplements containing certain kinds of live bacteria. Potential benefits of probiotics have been approved as treatment or prevention from the following diseases:

irritable bowel syndrome
ulcerative colitis
Crohn's disease
vaginal infections
urinary tract infections
recurrence of bladder cancer
heart diseases
digestive tract infections
skin eczema

Always talk to your doctor before taking any supplement, as there are thousands of types of bacteria and you need to find the right solution for your specific case.
