Do probiotics improve mood? Scientific research is growing interested in the relationship between these supplements and mood, and emerging results suggest that some do exactly that. These live microorganisms, confer health benefits when consumed. Now, many are seeing that they do improve mood. In this post, we try to answer the question, “Can probiotics improve mood?” and go over how to use probiotics to improve mood.
How Do Probiotics Improve Mood?
While many studies have been conducted in animals, there is also emerging evidence from human studies. Some clinical trials have shown promising results regarding the use of specific strains in improving mood and reducing symptoms of depression and anxiety. The results often speak for themselves, but, of course, scientists like to understand why. There are three main mechanisms by which they improve mood in studies:
1. Gut-Brain Axis
The gut-brain axis is a bidirectional communication between the gastrointestinal and central nervous systems. Using probiotics to improve mood involves influencing this axis by modulating the gut microbiota composition and activity, affecting brain function. Specifically, they positively influence the production of neurotransmitters such as serotonin, dopamine, and gamma-aminobutyric acid (GABA) in the gut. These neurotransmitters play crucial roles in regulating mood and emotional well-being.
2. Probiotics Improve Mood By Reducing Inflammation
Some research regarding how do probiotics improve mood suggests that they can help reduce inflammation in the body and the brain. Chronic inflammation has been linked to mood disorders such as depression and anxiety. Thus, they may improve mood by reducing inflammation. Can probiotics improve mood if they reduce inflammation – the evidence may be circumstantial, but it is compelling.
3. Probiotics Improve Mood By Reducing Chronic Stress
Finally, probiotics may also influence the body’s response to stress. Chronic stress can negatively impact mood, and certain strains have been shown to mitigate stress responses in animal studies. Can probiotics improve mood by reducing stress? Again, there is evidence to back that possibility.
Specific Studies
Research suggests the strong possibility that probiotics improve mood through the mechanisms listed above. For example, a review published in the 
journal “Nutrients” in 2016 concluded that certain strains, particularly those belonging to the *Lactobacillus* and *Bifidobacterium* genera, may have beneficial effects on mood and psychological conditions like anxiety and depression. It’s important to note that not all studies have consistently demonstrated significant mood improvements with probiotic supplementation. Factors such as the specific strains used, dosage, duration of supplementation, and individual variability can all play a role in determining the chances that probiotics improve mood.
While these supplements hold promise as a potential adjunctive therapy for mood disorders, they should not be viewed as a standalone treatment for conditions like depression or anxiety. If you are experiencing significant mood disturbances, seek guidance from a qualified healthcare professional for proper evaluation and treatment.
Using Probiotics to Improve Mood
To use probiotics to improve mood, you need to consider the following factors:
- Strain Specificity: Benefits are often strain-specific. Not all strains have the same effects, so choosing strains shown to improve mood is important. A strain that helps someone else may not be ideal for you, so you may have to try different products.
- Dosage and Duration: The treatment’s effective dose and duration can vary. Most studies suggest a period of at least 4-8 weeks to see significant mood improvements. Can probiotics improve mood more quickly? Perhaps, but that should be a pleasant surprise rather than an expectation.
- Diet and Lifestyle: These supplements should be part of a holistic approach to mental health, which includes a balanced diet, regular exercise, adequate sleep, and stress management techniques.
- Safety: Do probiotics improve mood safely? The answer is simple: While they are generally considered safe for most people, individuals with compromised immune systems or severe illnesses should consult a healthcare professional before starting these supplements.
Using probiotics to improve mood, alongside other lifestyle improvements, can provide the boost you need.

Recommendations
- Consult a Healthcare Provider: Before starting any new supplement, it’s important to discuss it with a healthcare provider, especially if you have underlying health conditions or are taking other medications.
- Select High-Quality Probiotics: Look for supplements that specify the strains and CFU (colony-forming units) on the label. Quality can vary between brands, so choosing reputable products is crucial.
- Monitor Your Response: Track any changes in your mood and overall well-being after starting any supplement. This can help you and your healthcare provider determine their effectiveness.
Summary and Conclusions
Can probiotics improve mood? The bottom line is that more research is needed to understand their role in mental health and identify the most effective strains and treatment protocols. While these organisms likely can improve mood, they should not be considered a substitute for conventional treatments for mood and other mental health disorders. Anyone considering psychobiotic supplementation for mood-related concerns should consult with a healthcare professional. Do probiotics improve mood? Let us know if they worked for you!
