From nowhere to everywhere in less than 15 years, probiotics have come a long way. But, we need reminding how the concept was created, and not by Metchnikoff in Bulgaria. We must understand the importance of the definition. Companies use the term on labels, but too many simply add bacteria or yeast to a bottle and call it a probiotic without the necessity of human studies. The probioticchart.ca site tells consumers the starting point to purchase a probiotic, but it should also alert companies to make sure all their products are proven. This webinar will take the viewer from conception to how we think probiotics work and where the future lies for their application to planetary health.
