Probiotics – Are They a Useful Add-on to Traditional Anxiety and Depression Treatments?

More people nowadays are looking for additional ways to feel better than just the traditional mental health treatment options alone. Therapy and medication remain the main forms of treatment for depression, anxiety, and other conditions. But we’re also becoming more aware of how our physical health and lifestyle play an important part in our emotional well-being.

One of the areas that’s getting more attention lately is the connection between the digestive system and the brain, called the “gut-brain axis”. The idea behind the gut-brain connection is that poor gut health can not only impact our physical health but also our mental and emotional wellness. And probiotics play a big role in balancing out the health of our gut. 

Because of probiotics’ benefits, this article will help you understand the connection between physical and mental health and how probiotics might be able to support mental health.

What Are Probiotics and Why Are They Being Talked About for Mental Health?

Probiotics are live microorganisms (bacteria or yeast), often referred to as “good bacteria,” that can help improve the health of our digestive system.[1] They’re found in certain foods like yogurt, kefir, sauerkraut, and kimchi, as well as in supplement form. What these good bacteria do is fight off the bad bacteria or infections. Having a healthy gut helps with:[2]

  • Breaking down and absorbing certain nutrients and minerals.
  • Breaking down and recycling waste after digestion.
  • Helping to train our immune systems to recognize and eliminate harmful microbes.

Interest in probiotics for mental health has grown as researchers explore how improving gut health might influence emotional well-being. Some scientists even use the term “psychobiotics” to describe probiotics that may have mental health benefits.[3] The idea is that if gut bacteria influence mood, then supporting a healthy microbiome could potentially support mental health. 

Understanding the Gut-Brain Axis: Connection Between Physical and Mental Health 

The gut-brain axis is a system that interacts in two directions (bidirectional). Communication flows from the brain to the digestive system, and vice versa.[4] It’s easy to think of mental health as something that exists only in our thoughts or feelings. But the reality is that our mental and physical well-being are closely connected. The body is one system, so what happens in one area impacts the rest of it. 

Inside our digestive system is the microbiome, a complex community of bacteria that supports various bodily functions. These bacteria are involved in processes like inflammation, immune response, and even the production of neurotransmitters such as serotonin, which helps regulate mood.[5] 

The clearest example of the connection between physical and mental health that you may have noticed is when you’re stressed or anxious. During times of intense stress or anxiety, you’re not just experiencing emotions; you’re probably also having physical symptoms like: 

  • Nausea.
  • Diarrhea.
  • Muscle tension. 

If you’re experiencing depression, you might also notice this connection in: 

  • Difficulty sleeping.
  • Fatigue.
  • Lack of appetite. 

These experiences are a reminder that our physical and mental health are deeply intertwined.

While gut health is not the sole cause of anxiety or depression, it can be an important piece of the bigger picture. 

Potential Benefits of Probiotics for Anxiety and Depression

Research is still evolving into the effect of probiotics on depression and anxiety. Though there are quite a few studies that suggest it’s beneficial to use probiotics for mood improvement.[6] The biggest challenge is that there are several different kinds of probiotics that affect the body in different ways. Here are some of the probiotics and how they might benefit depression or anxiety:

  • Some probiotics, specifically Lactobacillus rhamnosus GG (LGG), may help reduce stress.[7]
  • Research has shown that probiotics like L. acidophilus (LA-1) reduce inflammation.[8] Experts have linked chronic inflammation to mood disorders, and a healthy gut may help reduce inflammatory responses.[9]
  • Studies show that the probiotic Lactobacillus plantarum JYLP-326 may help alleviate sleep issues, like insomnia.[10]

While there are potential mental health benefits of probiotics, it’s important to be clear about what they can and cannot do. Despite the growing interest in the microbiome and depression, probiotics are not a cure.

Mental health conditions are complex and influenced by a combination of biological, psychological, and environmental factors. So improving gut health alone is unlikely to resolve deeper emotional challenges. Instead, you may find that the best course of action is to use probiotics as an add-on to therapy and medication, if needed, not as the only form of treatment.  

When It’s Time to Look Beyond Supplements

While you might find probiotics helpful, they are not a substitute for professional mental health care. If you’re experiencing persistent anxiety, low mood, or difficulty functioning in daily life, it may be time to seek more structured support. You might need additional help if you’re experiencing:

  • Ongoing feelings of sadness or hopelessness.
  • Increased anxiety that interferes with daily activities.
  • Difficulty maintaining relationships or responsibilities.
  • Lack of improvement despite self-help efforts.

In these situations, the most effective approach to managing symptoms is to address your whole wellness. This often includes evidence-based therapies such as cognitive behavioral therapy (CBT) or dialectical behavior therapy (DBT), along with medication when appropriate. Within this whole-person approach, you and your provider might consider using probiotics as a supportive tool, rather than a primary treatment.

It’s also important to consider how probiotics and medications interact. In most cases, probiotics are safe to use alongside prescribed treatments, but it’s always best to check with a healthcare provider before adding any supplement.

By viewing probiotics as one piece of a larger plan, you can avoid relying on them too heavily while still exploring their potential benefits.

Probiotics and Mental Health FAQ

To help you better understand the connection between probiotics and mental health, we’ve answered some of the most common questions about their role in mental health.

Yes, gut health can affect mental health. Our physical and mental health are deeply connected. When we’re not feeling physically well, it’s harder to feel mentally well, and vice versa. 

The gut is also a major producer of the neurotransmitter serotonin, producing around 90% of the body’s supply.[1] 

This chemical plays a big role in our emotions. So while gut health alone doesn’t determine your mental state, imbalances in the microbiome suggest it can play a contributing role.

The research is still evolving, but there are several studies that support evidence that probiotics can improve mental health, specifically depression and anxiety.[2] 

However, they are not a standalone treatment and work best when used alongside therapy, medication, and other evidence-based approaches.

According to research, some of the best probiotics for mental health include strains of Lactobacillus and Bifidobacterium species.[3] 

Experts have studied these strains for their potential role in mood improvement. However, results vary, and what works for one person may not work for another.

Research shows that some probiotics could improve negative feelings in about two to eight weeks.[4] Though this timeline varies based on the severity of your symptoms, overall health, and whether you combine them with other treatments.

There are many different probiotic strains that have varying effects on physical and mental health. While what’s best for one person might have no effect for another, there is research that supports how the probiotic strains Lactobacillus helveticus R0052 and Bifidobacterium longum may improve symptoms of depression.[5]

But really, there is no definitive answer because the relationship between the microbiome and depression is complex. A healthcare provider can help determine whether they may be appropriate for your specific needs.
