What are Probiotics?

Probiotics may help with the growth of good bacteria, which promotes a balance between harmful and beneficial bacteria. In addition, about 70% of the body’s immune system is located in the digestive tract. A healthy digestive system can help promote overall wellness of the body.

As a Greek word, "Probiotic" means "for life." As defined by the Food and Agriculture Organization of the United Nations (FAO) and World Health Organization (WHO) in 2002, probiotics are "Live microorganisms which when administered in adequate amounts confer a benefit on the host."
