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."
Probiotics are friendly bacteria or yeasts that have been used for centuries as natural ingredients. Recent scientific studies support the many benefits of probiotics. Yakult is the only probiotic product in the world that contains our exclusive probiotic strain, Lactobacillus casei Shirota.
