“We see a lot of patients [with celiac] and we have a lot of patients who have it and don’t feel better,” says Dr. Peter Green, professor of medicine and director of the Celiac Disease Center. “We found previously that about 25% of celiac patients use supplements or non-traditional medical products, and probiotics were the largest and most frequently consumed. Those people [who used probiotics] had more symptoms compared to people who weren’t taking these supplements.”
