Probiotics Reference Guide

What are probiotics?

Probiotics are friendly or "good" bacteria that, when ingested in adequate amounts, are beneficial to health. These healthy bacteria fight harmful bacteria, preventing illness and gastrointestinal infections. In the marketplace, probiotics are most commonly found in yogurt but also in other fermented foods such as miso, raw kimchi, raw sauerkraut, and kefir; they are found in much greater quantities in probiotic supplements. Depending on the symptoms, a person may benefit from taking probiotics to improve gastrointestinal health. Discuss your situation and specific symptoms with your doctor or dietitian and decide whether you might benefit from probiotics.


The Celiac Center is providing this list as a useful resource on probiotics; however, the hospital is not endorsing or recommending the use of probiotics, any particular product or specific brand. This list can be used as a reference for clinicians wishing to recommend a probiotic to their patients, or for patients to refer to when deciding with their clinician if a probiotic is right for them. The information about these products comes from their websites, customer service representatives, and published data. Always check with the manufacturer to be certain the product is gluten free as ingredients on labels may change at any time. This guide is not comprehensive. Please note that many of the probiotics claims are not proven by any clinical data. December 2009.
