Psychobiotics Regulate the Anxiety Symptoms in Carriers of Allele A of IL-1<i>β</i>Gene: A Randomized, Placebo-Controlled Clinical Trial

Abstract

Consumption of probiotics mitigates anxiety symptoms, especially in healthy adults with the minor A allele of rs16944 as a risk factor. Our results encourage the use of probiotics in anxiety disorders and suggest genetic association studies for psychobiotic-personalized therapy.
