What Are the Common Types of Bacteria Found in Probiotics?

Many types of bacteria can be considered probiotics. Of these, two specific types are commonly found in probiotic supplements available in stores. These include:

1. Lactobacillus: commonly used for infectious diarrhoea and diarrhoea in people taking antibiotics.^[1]
2. Bifidobacterium: commonly used for diarrhoea, constipation, irritable bowel syndrome (IBS) and preventing the common cold.^[2]

Probiotics are also made up of good yeast. Saccharomyces boulardii is one such probiotic commonly used for treating and preventing diarrhea.^[3]
