Efficacy of Probiotic ES1 for the Treatment of Non-Celiac Gluten Sensitivity

A Randomized, Double-Blind, Placebo-Controlled Study on the Efficacy of Bifidobacterium Longum Probiotic ES1 for the Treatment of Non-Celiac Gluten Sensitivity

Study to demonstrate the efficacy of Probiotic ES1 in alleviating symptoms of gluten sensitivity in non-celiac gluten sensitive subjects exposed to a small, fixed amount of gluten.

This is a randomized, double-blind, placebo-controlled study. Sixty non-celiac gluten sensitive subjects will be randomized into one of two groups; Probiotic ES1 or placebo. For the duration of the study, subjects must adhere to a gluten-free diet, apart from a scheduled fixed gluten exposure of two slices of bread once daily. Subjects will be required to take 1 capsule before and after consuming the two slices of bread and score the severity of their symptoms in a diary provided for the duration of the study (7 days).
