“Right now, we don't have a lot of proof that taking probiotics is going to change depression or anxiety. Those who had received the probiotic exhibited significant increases in Lactobacillus and Bifidobacteria bacteria within excrement compared to the placebo controls. Researchers highlight that peripheral ENS neurons can influence the vagus nerve, particularly vagal afferents (or those signaling to the CNS). We include products we think are useful for our readers. (2007) assessed the effect of Lactobacillus acidophilus on the gut of animal models. Results indicated that all mice (regardless of whether WT or IL-10) eating the Western diet had weight gain along with anxiety and increased cytokine expression (signifying inflammation). Thereafter, they treated the rats with the probiotic Lactobacillus helveticus (strain NS8). While probiotic or combination prebiotic and probiotic interventions effectively reduced the symptoms of depression, the authors found little evidence for them reducing the symptoms of anxiety. A second study published in 2013 assessed the interaction between diet, gut microbiota, and genetics of mice. Research is ongoing into the relationship of the gut microflora to disease.

Hypothetically, it could be that Lactobacillus acidophilus upregulates peripheral (and possibly central) CB2 receptors and, as a result, improves mood. While sepsis only occurs in a small percentage of the population, particularly those with compromised immune function, it should be noted as a potential adverse reaction. Additionally, there were significant changes on BAI (Beck Anxiety Inventory) scores among those receiving the Lactobacillus casei Shirota (LcS) strains compared to the controls. A study published in 2011 discovered that Citrobacter rodentium was implicated in stress-induced memory dysfunction in mice. Worth a read: http://www.nature.com/articles/srep43859?WT.mc_id=FBK_SREP_1703_MICROBIOTAALTERATION_OA. In addition, patient’s anxiety, depression, and quality of life were also evaluated. It is plausible that those with an already-good mood may already have adequate Lactobacillus casei Shirota (LcS) within their gut, whereas those with poorer moods may have had less Lactobacillus casei Shirota (LcS) and ultimately benefitted. Close to 6.5 million American seniors are quietly struggling with depression right now. Those with depression and anxiety often derive benefit from drugs that inhibit the activity of the monoamine oxidase enzyme. I deal with this by taking this probiotic every 3 or 4 days.
