However, the mind-body connection is very important as it significantly improves the overall wellbeing of a person. This is why certain professionals are trained in understanding and improving this connection. [Prof Nanette Mutrie of the University of Edinburgh’s Institute for Sport](https://www.theguardian.com/lifeandstyle/2019/dec/02/one-step-at-a-time-exercise-mental-health), Physical Education and Health Sciences, outlines how the brain releases endorphins when we exercise, as well as dopamine and serotonin. She notes that: “very often, these same chemicals form part of antidepressant drugs”. This is why the mind-body connection has also become a prominent field of study for the biological aspects of human behavior. As a result, the biological aspects of human behavior is considered a key part of higher education research across top universities. [Maryville University’s psychology degree](https://online.maryville.edu/online-bachelors-degrees/psychology/) highlights how biological psychology is one of the core courses for modern psychologists. And the studies undertaken at universities by biological psychologists have allowed dietitians to better understand how nutrition plays a role in both physical and mental health. One of the major findings has been the effect probiotics have on a person’s mood. Probiotics are a combination of good live bacteria and/or yeasts that are most popularly known to improve your digestive system. However, these can also positively impact your mood in a few ways: #### **Boosts cognitive function** Cognitive function refers to mental abilities such as learning, reasoning, and remembering. But aside from simply boosting these abilities, [a study in The Journals of Gerontology](https://academic.oup.com/biomedgerontology/article/76/1/32/5821144) also concludes that probiotics promote mental flexibility and can help prevent mental decline. This includes enhancing the cognition of those with Alzheimer’s disease and mild cognitive impairment. The study suggests that this might be due to probiotics improving the interaction between the central nervous system and gut microbiota. #### **Lower stress and anxiety** Stress can cause anxiety by disrupting the balance of the intestinal microbiota. [A study on Science Direct](https://www.sciencedirect.com/science/article/pii/S2352289521000023) mentions that probiotics, and in effect some gut bacteria, can lower levels of cortisol -- which is a primary stress hormone. It can also balance the intestinal microbiota through its immunomodulatory effects, which essentially helps improve your immune system. This creates T-regulatory cells to limit chronic inflammatory diseases, and cytokines to regulate immunity and inflammation. These can activate immune pathways throughout your body, helping lower stress levels and improve mood. #### **Reduce symptoms of depression** In relation to the previous point, depression can also arise from the disturbance of the balance of intestinal microbiota. Probiotics reduce inflammation-related processes such as oxidative and nitrosative stress, and damage to mitochondria that can contribute to depression. Other conditions that can cause depression, such as irritable bowel syndrome and other gastrointestinal problems, can also be relieved by the intake of probiotics. #### **Improves overall sense of well-being** Probiotics help you keep a healthy balance in your body. Aside from helping your body digest food, they also help enhance your immune system and reduce the risk of certain diseases, such as acute respiratory tract infections and acute infectious diarrhea. Along with these benefits, probiotics can also affect the mind through the gut-brain axis, which essentially links your central nervous system to your gastrointestinal tract. Communication along the axis also involves neural, endocrine, and immune pathways. These pathways are usually found to be altered in the cases of mental problems, such as depression and anxiety. Overall, intake of probiotics can help keep your gut healthy and improve these pathways, which will improve your overall sense of well-being. #### **Creates postbiotics** Probiotics are still living organisms, they need to eat in order to live. When they eat and ferment foods, they produce more beneficial compounds called postbiotics. [Our post What Are Postbiotics and What Are Their Benefits?](https://www.scdprobiotics.com/blogs/news/what-are-postbiotics-and-what-are-their-benefits) explains how the benefits of postbiotics depend on the type of probiotic it came from. Just a few benefits of postbiotics are supporting metabolism, helping insulin work more effectively, and reducing the effects of chronic illnesses like Crohn’s disease. There are many probiotic-rich foods aside from yogurt, such as kimchi, miso, pickles, and buttermilk. It should be noted, however, that the area of research on probiotics and its effect on the gut-brain axis is still in an extremely early stage. While there have been studies to determine how exactly probiotics affect the gut-brain axis, further research is still needed.   *Exclusively written for SCDProbiotics.com* *By: Riya Jessa* ### [![Join the SCD Probiotics Affiliate or Distributor Program for Practitioners and Influencers](https://no-cache.hubspot.com/cta/default/19514145/176ff363-ae8b-4c20-a166-a21a6123cf2d.png)](https://cta-redirect.hubspot.com/cta/redirect/19514145/176ff363-ae8b-4c20-a166-a21a6123cf2d) [Gut Health](https://blog.scdprobiotics.com/tag/gut-health) ### Sale Products [![SCD Bio Ag - Microbial Inoculant & Soil Amendment](https://blog.scdprobiotics.com/hubfs/bio-ag_b8f8172c-389a-4b3e-9240-e27bb18ab0c0-1.jpg)](https://www.scdprobiotics.com/products/scd-bio-ag-soil-amendment) [SCD Bio Ag - Microbial Inoculant & Soil Amendment](https://www.scdprobiotics.com/products/scd-bio-ag-soil-amendment) $19.75 [![SCD Probiotic All-Purpose Cleaning Concentrate-Lemongrass](https://blog.scdprobiotics.com/hubfs/cleaningLG-1.jpg)](https://www.scdprobiotics.com/products/scd-probiotic-all-purpose-cleaning-concentrate-lemongrass) [SCD Probiotic® All-Purpose Cleaning Concentrate – Lemongrass, Concentrated, Natural Household Cleaner - 16.9 oz](https://www.scdprobiotics.com/products/scd-probiotic-all-purpose-cleaning-concentrate-lemongrass) $17.39 [![30 Day Supply Liquid Probiotic Supplement](https://blog.scdprobiotics.com/hubfs/EP11.png)](https://www.scdprobiotics.com/products/scd-essential-probiotics-liquid-probiotic-supplement) [SCD Essential Probiotics - 30 Day Supply Liquid Probiotic Supplement 16.3 fl. oz](https://www.scdprobiotics.com/products/scd-essential-probiotics-liquid-probiotic-supplement) $35.59 [Share on Facebook](http://www.facebook.com/sharer/sharer.php?u=https://blog.scdprobiotics.com/how-probiotics-in-your-diet-can-impact-your-mood) Share on Twitter [Share on Email](mailto:?body=https://blog.scdprobiotics.com/how-probiotics-in-your-diet-can-impact-your-mood) [Share on Pinterest](https://pinterest.com/pin/create/button/?url=https://blog.scdprobiotics.com/how-probiotics-in-your-diet-can-impact-your-mood) [Fermented Coffee Offers New Flavors for Old Favorites](https://blog.scdprobiotics.com/fermented-coffee-offers-new-flavors-for-old-favorites) [Back to News](https://blog.scdprobiotics.com) [Coronavirus: Known COVID-19 Symptoms, How to Respond, and How to Support Your Immune System Naturally](https://blog.scdprobiotics.com/coronavirus-known-covid-19-symptoms-how-to-respond-and-how-to-support-your-immune-system-naturally) #### Related Articles ##### [Probiotic Foods vs. Probiotic Supplements: What’s Better for Your Gut?](https://blog.scdprobiotics.com/are-probiotic-foods-better-than-probiotic-supplements) June 12 2025 ##### [Probiotics and Anxiety: How Your Gut Bacteria Affect Mental Health](https://blog.scdprobiotics.com/probiotics-and-anxiety-how-your-gut-bacteria-affect-mental-health) March 25 2025 ##### [Benefits of Elderberry Backed by Science: A Natural Powerhouse for Wellness](https://blog.scdprobiotics.com/benefits-of-elderberry-backed-by-science-a-natural-powerhouse-for-wellness) January 17 2025 ##### [What Are Probiotics and Postbiotics, and Why Are They Essential for Gut Health?](https://blog.scdprobiotics.com/what-are-probiotics-and-postbiotics-and-why-are-they-essential-for-gut-health) December 20 2024 ##### [Probiotics for C. diff: Prevention and Treatment](https://blog.scdprobiotics.com/probiotics-for-c.-diff-prevention-and-treatment) May 30 2024 ![Blue-Black-SCD-Probiotics-Discovery-Call-Business-Card](https://blog.scdprobiotics.com/hubfs/Blue-Black-SCD-Probiotics-Discovery-Call-Business-Card.jpg) ### Let's Talk!
