Probiotics are the “good” bacteria that aid in the body’s gut and digestive health. Probiotics help keep your system in a state of bacterial balance. It may seem odd that we want to supplement our bodies with bacteria, as we usually think of bacteria as harmful for the body. However, our body contains both good and bad bacteria, and supplementing with more beneficial bacteria can help our bodies with a wide range of problems. Probiotics also help the body break down food, aiding proper digestion.
