Low Levels of Faecalibacterium prausnitzii on a recent stool test? In the rapidly evolving field of gut health research, one bacterium has garnered significant attention for its numerous benefits, Faecalibacterium prausnitzii. An integral player in our gut microbiome, this beneficial microbe is often cited as a key indicator of a healthy digestive system. However, emerging studies reveal a concerning trend—many individuals are experiencing alarmingly low levels of Faecalibacterium prausnitzii on stool testing, which is linked to a range of health issues.

In Today’s article, Ill explain just how important this powerhouse commensal bacteria is, explore the problems when you find low levels on a stool test, and lastly review some of the Best Probiotics To encourage growth of Faecalibacterium prausnitzii.

Whether you’re a health enthusiast or someone struggling with gut health problems, understanding the impact of low levels of Faecalibacterium prausnitzii could be a vital piece of the puzzle in achieving optimal well-being.

What is Faecalibacterium prausnitzii?

To understand what problems may be associated with low levels of this bacteria on a stool test, we first need to understand the role and the job of Faecalibacterium prausnitzii in other words what does it do that makes it special?

Faecalibacterium prausnitzii is a crucial and highly abundant bacterium in the human gut microbiota, accounting for over 5% of the total bacterial population in a healthy gut. Known for its beneficial role in maintaining gut health, this anaerobic bacterium belongs to the Firmicutes phylum and is commended for its potent anti-inflammatory properties (*). Unlike many other bacteria, Faecalibacterium prausnitzii produces short-chain fatty acids (SCFAs), particularly butyrate, which are vital for colon health, immune function, and overall well-being.

Why Are Low Levels of Faecalibacterium prausnitzii a Problem?

The significance of low levels of Faecalibacterium prausnitzii cannot be understated. This bacterium plays a critical role in sustaining the integrity of the gut lining, reducing inflammation, and fostering a balanced immune response.(*),(*) Consequently, having low levels on stool testing is a significan problem. Low levels can trigger diverse and troubling gastrointestinal symptoms and conditions.

Low Levels prausnitzii

Lower levels prausnitzii are often associated with:

1. Increased Inflammation: Without sufficient Faecalibacterium prausnitzii, the production of butyrate diminishes, leading to weaker anti-inflammatory defenses(*). Butyrate, a short-chain fatty acid, is known to play a crucial role in maintaining gut health. It provides energy to colonocytes, aids in maintaining the intestinal barrier function, and has anti-inflammatory properties

2. Gut Dysbiosis: Imbalanced gut flora can result in adverse changes to the microbiome, promoting the proliferation of pathogenic bacteria (bad bacteria) over beneficial ones.

3. Compromised Immune Function: This beneficial bacterium helps modulate the immune system(*), and its deficiency might trigger inappropriate immune responses contributing to a host of issues.

Faecalibacterium prausnitzii and Inflammatory Bowel Disease (IBD)

Low levels of Faecalibacterium prausnitzii and IBD—including Crohn’s disease and ulcerative colitis—are widely recognized to be intimately linked.(*) Research has consistently shown that patients with IBD have reduced populations of F. prausnitzii in their intestines. Heres  a few ways how IBD and Faecalibacterium prausnitzii are connected.

1. Anti-inflammatory Mechanisms: Faecalibacterium prausnitzii generates anti-inflammatory molecules like butyrate and salicylic-like molecules, contributing to the suppression of inflammatory pathways. If you have low levels of F. prausnitzii these anti-inflammatory buffers that keep inflammation in check are lost. This exacerbating gut inflammation is a hallmark inIBD patients(*). One of the ways we measure inflammation in Functional medicine is by measuring calprotectin levels and Eosinophil Protein X levels.

2. Barrier Function: Faecalibacterium prausnitzii supports the production of mucin, a primary component of the gut’s mucus layer that constitutes a crucial first-line defense. Without adequate levels, the protective barrier weakens, facilitating the entry of disease causing bacteria and exacerbating inflammation.

3. Immune Regulation: Faecalibacterium prausnitzii modulates immune responses and maintains regulatory T-cells(*), essential for immune tolerance. A deficiency in F. prausnitziican lead to dysregulated, overactive immune responses characteristic of IBD. IBD is an autoimmune disorder.

Best Way To Increase Low Levels of Faecalibacterium prausnitzii

Given its vital role, enhancing Faecalibacterium prausnitzii levels represents a promising avenue for improving gut health and managing conditions like IBD:

1. Dietary Interventions: A diet rich in prebiotics (such as resistant starch, inulin, and pectin) can boost the growth of Faecalibacterium prausnitzii. Foods like whole grains, bananas, apples, and asparagus are good sources.

2. Probiotics and Synbiotics: While direct supplementation of Faecalibacterium prausnitzii is currently challenging, new synbiotic formulations show potential in promoting its growth within the gut microbiota.

3. Lifestyle and Environmental Factors: Regular exercise, stress management, and avoiding unnecessary antibiotic use can help maintain a healthy gut environment conducive to beneficial bacterial growth.

4.Butyrate Supplementation- butyrate can create a healthier environment in the gut, which may indirectly support the growth of beneficial bacteria, including F. prausnitzii.

5.Fermentable Fiber- F. prausnitzii is known to thrive on fermentable dietary fibers and prebiotics, a diet rich in these compounds can help boost its levels. Foods like fruits, vegetables, legumes, and whole grains are excellent sources.

Best Probiotics To Boost Low Levels of Faecalibacterium prausnitzii

While direct supplementation of Faecalibacterium prausnitzii is not yet commercially available, you can support and increase its levels in your gut through certain probiotics and lifestyle changes that promote a healthy microbiome environment.

Probiotic strains such as Bifidobacterium Infantis, Lactobacillus Rhamnosus GG, and Lactobacillus Plantarum can be beneficial in enhancing gut health and promoting the growth of beneficial bacteria like Faecalibacterium prausnitzii. These strains are often found in multi-strain probiotic supplements like Orthobiotic 100, known for their potency and diverse bacterial footprints, which help rebalance gut dysbiosis.

In addition to probiotics, focus on consuming prebiotics like resistant starch, inulin, oligofructose, and pectin. Resistant starch can be obtained from foods like cooked and cooled potatoes, green bananas, and legumes.

Inulin and oligofructose are present in foods such as chicory root, garlic, onions, and artichokes, while apples and citrus fruits provide pectin. These prebiotics are fermented in the colon, providing essential substrates for Faecalibacterium prausnitzii and other beneficial bacteria.

Synbiotics, which combine prebiotics and probiotics, can also play a significant role in enhancing gut health by optimizing conditions in the gut to support beneficial bacteria.

Besides specific probiotic and prebiotic interventions, adopting a high-fiber diet and including a diverse range of fibrous foods can promote the growth of beneficial gut bacteria. Regular physical activity and exercise positively influence gut flora composition, while stress management techniques like mindfulness, yoga, and meditation mitigate stress-related gut issues.

It is essential to practice antibiotic stewardship to avoid unnecessary antibiotic use, as these can drastically alter gut microbiota. When antibiotics are necessary, supplementing with probiotics subsequently may aid in restoring microbial balance.

Understanding the importance of maintaining adequate levels of Faecalibacterium prausnitzii can guide you towards strategies that promote its growth and mitigate inflammation, particularly in the context of inflammatory bowel diseases (IBD).

By leveraging specific probiotic strains, prebiotics, synbiotics, and responsible lifestyle choices, you can fortify your gut health and support a balanced microbial environment that fosters the proliferation of Faecalibacterium prausnitzii.

In summary, low levels of Faecalibacterium prausnitzii have profound implications for gut health, particularly in the context of IBD and inflammation. Understanding and addressing its deficiency can pave the way for new preventative and therapeutic strategies, offering hope for those affected by chronic inflammatory conditions.
