Recently, there has been a lot of hype on the role of probiotics in promoting health. Almost everyone with a digestive problem is prescribed probiotics. They are essentially bacteria which are good for your health. Probiotics contain good bacteria that are very similar to the bacteria found in the human gut. Certain types of bacteria like lactobacillus and bifidobacteria are present in the intestinal flora and the gut lining.

The lower digestive tract is home to complex and varied strains of healthy bacteria that are more in number than the cells in one’s body.

What are probiotics made of?
They are foods that contain bacterial strains having similar properties as the healthy bacteria present in the intestinal lining. FDA regulations treat probiotics as foods and not medications.
