Probiotics may ease stress-related gut problems

Using a proprietary probiotic supplement, researchers report that abdominal pain and nausea/vomiting were reduced significantly compared to placebo, according to results of a double-blind, placebo-controlled, randomized study published in the journal Nutrition Research.

The preparation contained Lactobacillus acidophilus and Bifidobacterium longum.

"The human microflora is a complex ecosystem that contributes to the equilibrium of different gastrointestinal functions," explained researchers. "The potential beneficial effects of probiotics are due to the modulation of intestinal flora, modification to the mucosa to prevent the adherence of pathogens, and modulation of the immune system."
