Probiotics: "Live microorganisms administered in adequate amounts that confer a beneficial health effect on the host" (according to the Food and Agriculture Organization of the United Nations). Most probiotics are bacteria, which are small, single-celled organisms. Bacteria are categorized by scientists with genus, species and strain names.

Prebiotics: Food, such as the fiber inulin, that feed and stimulate the growth of the probiotic bacteria.

Live & Active Cultures: The National Yogurt Association confers a "Live & Active Cultures" seal on refrigerated yogurt when at least 100 million L. bulgaricus and S. Thermophilus per gram are used to ferment the yogurt; they are not considered a probiotic.
