Supplements fall under the broader category of nutraceuticals or functional foods. The probiotic supplement market is largely connected to increasing general knowledge among consumers about the increasing importance of probiotic supplements for overall human health and wellness. Demand is driven more and more by research from the scientific community about the role of the gut in immune function, metabolism, and mental wellness.
