Source of validity: Scientific
Rating (out of 5): 2

Lactobacillus salivarius is a probiotic bacterium that has been studied for its potential benefits in digestive health, including relief from acid indigestion (also known as dyspepsia or heartburn). The scientific evidence supporting its use for this condition is limited but emerging. Some small-scale clinical trials and animal studies suggest that L. salivarius may help balance the gut microbiome, suppress harmful bacteria, and strengthen the mucosal barrier of the gastrointestinal tract. These actions could potentially reduce symptoms of acid indigestion by improving overall digestive function and reducing inflammation.

Specifically, L. salivarius has been shown to survive gastric acidity and adhere to intestinal mucosa, where it may modulate local immune responses and inhibit the growth of pathogens such as Helicobacter pylori, a bacterium associated with gastritis and peptic ulcers. A few human studies have reported modest improvements in bloating, abdominal pain, and reflux symptoms in patients taking probiotics containing L. salivarius. However, these studies often use multi-strain probiotic formulations, making it difficult to attribute the effects solely to L. salivarius.

Overall, while there is a plausible scientific rationale for the use of L. salivarius in supporting digestive health and possibly easing acid indigestion, high-quality, large-scale clinical trials specifically targeting this condition are lacking. Therefore, the evidence is rated as low to moderate (2/5).
