Effects of heat-treated Lactobacillus gasseri CP2305 on brain oscillatory activity and mental stress in healthy adults: a double-blind, randomized, crossover, placebo-controlled trial (opens in new tab)

BackgroundGut health and brain activity are closely linked, and the gut−brain axis plays a crucial role in regulating mental health. Interventions using beneficial microbes, such as probiotics and postbiotics, are gaining attention as promising approaches to support mental health. This study aimed to evaluate the effects of postbiotic heat-treated Lactobacillus gasseri CP2305 (CP2305) on mental stress and alpha oscillatory activity in the brain.MethodsThis double-blind, randomized, crossover,...
