Exploring the Potential of Probiotics in Mood Regulation
Written on
Chapter 1: Understanding the Gut Microbiome
The human body harbors approximately 100 trillion microbes, primarily within the gastrointestinal tract, collectively known as the gut microbiome. Recent studies exploring the gut-brain axis have provided intriguing insights into the potential of probiotics—live microorganisms—to influence mental health. This leads us to question: could the FDA eventually recognize these probiotics as therapeutic agents for mood enhancement?
In a notable trial conducted in 2019 involving 38 healthy participants, a daily regimen of a probiotic blend featuring three strains of Lactobacillus and a single strain of Bifidobacterium resulted in notable mood improvements. The participants in the experimental group reported significant declines in feelings of depression, irritability, and fatigue.
Furthermore, research published in Frontiers in Aging (2016) highlighted that Alzheimer’s patients (n=30) who consumed milk enriched with probiotics over a 12-week period demonstrated significant enhancements in cognitive function, as measured by the mini-mental state examination (MMSE).
Aside from these studies, a plethora of human trials has consistently indicated that probiotics may positively influence mood and cognitive abilities.
Section 1.1: Common Probiotic Strains
The most prevalent bacteria found in probiotic supplements are Lactobacillus and Bifidobacterium. You can discover various species and strains of these microorganisms in both food products and dietary supplements.
Section 1.2: Safety and Regulations
Generally, probiotics are safe for consumption, except for individuals with compromised immune systems due to health conditions or medications. However, it’s important to note that probiotics are classified as dietary supplements, which means they are not subject to the same rigorous FDA oversight as pharmaceuticals. As a result, many companies market probiotics without adhering to strict regulations, leading to issues such as:
- Variability between batches
- Availability of subpar products
- Inconsistent dosages and strains
This lack of regulation can create confusion regarding the specific effects of particular microbes or combinations on overall health.
Chapter 2: Alternative Uses of Microbes
Another innovative application of microbes is fecal microbiota transplantation (FMT), often referred to as a "poo transplant." While the idea of ingesting fecal matter may sound unappealing, the process involves using stool from healthy donors, which is meticulously processed in stool banks like OpenBiome according to FDA standards. This material is then delivered to patients via colonoscopy.
FMT has become a recognized treatment for individuals suffering from severe, recurrent diarrhea caused by Clostridium difficile. The success of this therapy has prompted further research into its potential for treating a variety of other conditions, including Parkinson's disease, autism spectrum disorders, and various psychiatric illnesses, by comparing the microbiota profiles of affected individuals with those of healthy subjects.

Hope for the Future
The field of microbiome research is still in its infancy, with much yet to be discovered. The traditional approach of developing medications from chemical compounds, genetic materials, or proteins could soon evolve. The future of pharmacology might very well lie in harnessing the power of live organisms within our own bodies.
