A 2015 study at the Center tested 22 probiotic products purchased commercially and examined them for gluten. About 30 percent of them had some form of gluten that was not listed on the label. As a result, we feel that supplement labels claiming a product is gluten-free cannot currently be trusted.

This in some ways reconfirms a previous study we did showing that patients with celiac disease who regularly took supplements had more symptoms than those who did not take supplements. Interestingly, they also reported a higher quality of life. This may attest to the placebo effect of supplements—they make people better because we expect them to. The “action” would appear to be more brain than gut.

It is unclear whether the levels of gluten found in the probiotics tested posed a risk to people with celiac disease, but the results reflect the underlying problem of supplement oversight, regulation, labeling, and testing.
