Fermented foods such as yogurt, pickles, and kombucha use probiotics in the process of manufacturing. While many of these probiotics will survive from manufacturing to ingestion, many may not make it to the intestines alive. Probiotics are more likely to survive until they reach the intestines when a combination of probiotics and prebiotics—a food source for probiotics—are included in yogurt products. While food may contain probiotics, it will not contain as many probiotics as supplements. For those with antibiotic-associated diarrhea and pouchitis, yogurt won’t provide adequate probiotics. For all other healthy individuals, it will not harm you to have yogurt made with probiotics, but it may not help either.
