In this video, Dr. David Perlmutter discusses a recent Men's Health article titled “The Benefits of Probiotics Are Well-Documented, But Can They Improve Mental Health?” He highlights the article’s comprehensive review of the gut‑brain connection, emphasizing the role of the vagus nerve and, more importantly, gut bacteria and their metabolic products in influencing brain function. Perlmutter notes that depression is increasingly understood as an inflammatory disorder with much of its inflammatory origin rooted in the gut. While acknowledging that probiotics are not yet a standalone treatment for mental illness, he cites emerging research showing that certain probiotic strains can positively affect mood. He stresses the importance of lifestyle choices—diet, stress management, exercise, and sleep—in maintaining a healthy microbiome, linking these factors to overall mental health. Perlmutter also shares news that his book Brain Maker has been translated into Brazilian Portuguese and Russian, expanding its global reach. He concludes by encouraging viewers to read the article and stay tuned for further updates on microbiome health.

Hello everyone, Dr. Perlmutter here. A really interesting article just appeared in Men's Health, the online version, menshealth.com, and it is entitled, The Benefits of Probiotics Are Well-Documented, But Can They Improve Mental Health? And I think this is a really timely article because first, it went into great depth in terms of reviewing the connection between the gut and the brain, how that is mediated to some degree in a relationship by not only the vagus nerve that connects the two, but more importantly, the bacteria that live in the gut and the various metabolic products that they produce, how those metabolic products affect the brain. I was interviewed for this article as well as Dr. Emery Meyer. You know, we've talked to him on The Empowering Neurologist before, and I really again believe it was a very good overview. You'll see a link to the article accompanying this video. What they concluded I think was really very important, that first there is this powerful relationship. We've known that for a while, that depression, for example, is primarily an inflammatory disorder. We recognize that inflammation for the most part has its genesis within the gut. They really did also conclude that we're not yet at a stage where we can talk about treating mental illness with probiotics alone, and I would agree with that. They did, however, quote research that indicated that intervention using certain types of probiotic species has been proven effective, for example, in altering the mood in humans. And I think we're clearly at the very beginning of that research, but it is very, very exciting because we are seeing results. So I would offer up the advice to read this really intriguing and well-written article, again, in Men's Health. There's a lot to be said about caring for your microbiome. I think that's one of the areas they quoted me about was the idea that the foods we eat, for example, are really relevant in terms of Keeping the gut bacteria healthy. It is the focus of what we wrote about in the book Brain Maker, and I wanted to share other news with you that Brain Maker is now in Brazilian Portuguese. I just got this yesterday, and also now in Russian. So it's good. It's good that we're getting the message out now in over 30 languages around the world. That our lifestyle choices are really very important for us, not only because of their direct effects that have been studied for a long time, but for their effects on how they— our lifestyle choices affect our gut bacteria, and then secondarily, the important role of our gut bacteria in terms of our health. So, looking at our stress levels, our exercise, our sleep patterns, and perhaps most importantly, the foods that we choose to eat through the lens of how these choices affect our gut bacteria and their health, I think, is very, very important. So more news to come, that's for sure. Thanks for joining me. I'm Dr. David Perlmutter.
