Nervous System

Overview: The Nervous System & Biomunity™

The gut microbiome communicates with the Central Nervous System [CNS] and influences brain function and behavior through a bidirectional link known as the gut-brain axis. Through this axis, gut microbiota regulates gastrointestinal homeostasis and connect emotional and cognitive areas of the brain with functions of the gut. [1]


Biomunity Can Help

A well-modulated immune system fosters optimal brain functioning, which in turn supports mental acuity, mood management, and focus. Improved mental clarity, as well as mood, aids the ability to avoid and/or reduce stress and anxiety. [2] Biomunity provides Vitamins D3 which has been found to ameliorate symptoms of depression in people with insufficient levels. [3]

The Science

The gut-brain axis regulates various metabolic processes and, via specific gut microbial populations, produces metabolites that can affect the development of neurodegenerative diseases.  Intestinal dysbiosis may augment inflammation and blood-brain barrier permeability through the microbiota-gut-brain axis.

The vagus nerve represents the main component of the parasympathetic nervous system, which oversees a vast array of crucial bodily functions, including control of mood, immune response, digestion, and heart rate.  There is preliminary evidence for gut bacteria to have a beneficial effect on mood and anxiety, partly by affecting the activity of the vagus nerve.

Specific Ingredients that Help

CurQFen can influence brain waves in a manner consistent with penetration of the blood-brain-barrier.  It has been implicated for its influence on memory improvements and has been demonstrated to improve quality of life with considerable reduction in stress and anxiety. [2][4] 


Lactobacillus rhamnosus reduced stress-induced corticosterone and anxiety- and depression-related behavior in studies, suggesting an impact of the strain on the Central Nervous System at a physiological level.  Moreover, L. rhamnosus consistently modulates GABA receptors implicated in anxiety behavior. [5][6]


Lactobacillus plantarum reduces inflammatory cytokine levels, increases anti-inflammatory cytokine levels, and increases dopamine levels.  These results suggest that L. plantarum could ameliorate anxiety- and depression-like behaviors and modulate neurochemicals related to affective disorders. [7]


Vitamin D insufficiency is associated with depression, and Vitamin D supplementation and augmentation has been shown to ameliorate symptoms in those with clinical depression who are Vitamin D deficient. [3]
