Researchers at the Celiac Disease Center at Columbia University Medical Center used a detection technique called liquid chromatography-mass spectrometry to analyze 22 popular, high-selling probiotics and measure gluten content. The team found that more than half of them (55%) contained gluten, including products labeled "gluten-free," according to research presented on May 16 at Digestive and Disease Week in Washington DC.

For reasons doubtless including liability, the team did not list the names of the brands or products they tested. It is safe to assume that these would include major, easily accessible brands.

These revelations may be unsurprising, given recent reports about gluten contamination in dietary supplements.

So, if you have celiac disease or gluten intolerance, and take probiotic supplements, be sure to double-check your products; they may contain traces of gluten.
