Lactobacillus Rhamnosus, also referred to as L. Rhamnosus, is a bacterial microorganism that is commonly found in probiotic supplements used to promote healthy digestive function. L. Rhamnosus is one of many non-colonizing transient bacteria of the human gastrointestinal tract, and has been shown to provide notable benefits to neural pathways, the immune system, and in the treatment of candida.

As with other members of the Lactobacillus genus, L. Rhamnosus are aptly named for their production of lactic acid. Lactic acid is an organic compound that is found naturally in many dairy products (as a by-product of containing bacteria) and is also FDA approved as a food additive. When used as a food additive, Lactic acid serves as a powerful natural preservative, curing agent, and often a flavoring agent as well. These is a remarkable demonstration of how fermented foods, such as sour kraut and kimchi, are able to preserve foods. The bacteria that grown in these types of culture produce lactic acid which destroys harmful bacteria, and helps grow beneficial probiotics.

There is a large body of growing research that points to Lactobacillus Rhamnosus possessing the ability to have a tremendously-positive impact on gut health, as well neurological function. While there are some rare instances where L. Rhamnosus isn’t tolerated well, most people who introduce the lactic-acid producing bacteria into their system see some benefit. There are many different species within the Lactobacillus genus, and many of these compounds offer powerful gut-healing benefits. These compounds can be found in foods such as sour kraut and yogurt, and are also available for purchase as isolated supplements. For those simply looking for probiotics, you’ll find a table of supplements below—all of which contain Lactobacillus Rhamnosus.

L. Rhamnosus & Healthy Immune Function
Lactobacillus Rhamnosus is a powerfully beneficial non-colonizing bacterium that is part of the lactic acid producing genus, Lactobacillus. L. Rhamnosus is a common ingredient found in many probiotic supplements. Boasting data-backed potential to treat leaky gut syndrome, improve neural function, detox candida, and a plethora of other highly-effective health impacts, L. Rhamnosus can be a powerful addition to any dietary supplementation regimen. A quality probiotic can help aid in a great many facets of maintaining a healthy balance such as promoting favorable gut health, fighting common bacterial and fungal infections such as Candida Albicans, as well as helping to maintain robust neurological health as well.
There are a wide array of probiotic products on the market today, and most of them are comprised of a synergistic blend of several different organisms. To learn more about the importance of buying quality supplements, I suggest you read our article Pharmaceutical Grade Supplements, which details many of the risks of store brand supplements. Many of these high quality products restrict sales to licensed healthcare practitioners only— meaning local stores are unable to carry them. These brands make up a segment of the supplement market know as ‘Doctor Trusted Brands’, and are commonly prescribed by licensed Health Professionals to their patients to address health issues. To learn more about these types of brands, check out The Best Supplement Brands: A Comprehensive Guide & Review.
L. Rhamnosus & Gut Health
Lactobacillus Rhamnosus was discovered in 1983 1 living in the intestines of a healthy human subject, and was considered remarkable for its ability to thrive in highly-acidic environments such as stomach and digestive acids. It is this inherent ability which allows L. Rhamnosus to flourish in humans and promote robust gut health. As opposed to several other Lactobacillus strains, L. Rhamnosus is considered a transient strain 2—meaning that without semi-regular consumption it is unlikely to remain present in the GI tract. It is for this reason, that L. Rhamnosus supplements are vital for so many people in maintaining their overall gut health.
In 2010, a study published in Pediatrics 3found that when L. Rhamnosus was given to children with irritable bowel syndrome (IBS) a significant improvement of associated symptoms was seen. These benefits were seen, specifically, in the reduction of abdominal pain, and a decrease in bowel movement frequency. Nearly two-thirds of the children participating in the study showed signs of suffering from increased intestinal permeability (leaky gut). Those given L. Rhamnosus were able to shown marked improvements in follow up intestinal permeability tests, and overall gut health.
L. Rhamnosus & Candidiasis
Caused by an overgrowth of Candida, a type of fungal bacteria, Candidiasis most often presents as a white coating on the tongue or a vaginal yeast infection. While Candidiasis is a condition commonly experienced by women, men are very capable of falling victim to this yeast as well. In addition to tongue and vaginal issues, Candida has been known to grow to excessive amounts within the small intestines. Such overgrowths are thought to contribute to food sensitivities, leaky gut syndrome, chronic fatigue syndrome, as well as a host of other negative physical and mental conditions.
Lactobacillus Rhamnosus has been found to provide effective treatment for vulvovaginal candidiasis, a common vaginal yeast infection. Conjunction with other probiotics and, in some cases pharmaceutical-grade anti-fungals 4, L. Rhamnosus has been show to inhibit the growth of candida, allowing for effective elimination protocols to be enacted. Being that Candida is such a difficult condition to treat effectively, Lactobacillus Rhamnosus offers offers much needed hope to many.
L. Rhamnosus & Healthy Brain Function
While conducting a study on mice researchers found that those given a broth fortified with Lactobacillus Rhamnosus were less likely to show signs of anxiety. One of the most important chemical involved with regulating neurological pathways associated with stress and anxiety is Gama-Aminobutyric acid, or GABA for short. GABA is utilized within the brain by a protein referred to as the GABA receptor.
This important protein receptor, allowing for greater utilization of GABA within neural processing, was found to be present in much higher levels within the brains of mice fed the L. Rhamnosus-containing broth. In addition to higher levels of GABA and GABA receptor proteins, the mice were also shown to possess lower stress hormones, indicating that Lactobacillus Rhamnosus shows tremendous potential in the treatment of both stress and anxiety.
My experience with GABA is with the GABA by Pure Encapsulations, regarded world-wide as being a Doctor-Trusted supplement brand. It’s important to ensure you buy your supplements from companies that you trust to honestly label their products, and also choose to use quality products. Aside from ensuring you aren’t being exposed to unwanted toxins, allergens, or potentially hazardous compounds, a quality supplement can also help you gain an accurate account of how your body is affected during use.

While glucose is commonly regarded as being the primary source of energy for cellular tissue within the human body, there are also data to suggest that Lactate, a derivative of lactic acid, is preferentially chosen as metabolite of choice by neurons in the brain. That is to say; when given a choice, your brain would rather use lactate than glucose 5 to give its problem solving skills a boost. Highly supportive of dietary practices such as ketogenic diets, the Paleo diet, as well as other low-carb diet derivatives, this new concept of lactate—not glucose—being the preferred metabolite for neural cells turns many commonly-held dietary regards upside down. We’ve all heard of athletes “carbing-up” before a performance, but research suggests that we should also advice our “mathletes” to “lactate-up” before brain-intensive computations.
In addition to the above mentioned benefits, Lactobacillus Rhamnosus has shown marked ability to address the following medical concerns:
- Food Allergies & Intolerances
- Respiratory Tract Infections
- Urinary Tract Infections
While Lactobacillus Rhamnosus seems to show potential to address several health conditions, it has also been known to impact health conditions negatively in a small amount of cases. As with many other probiotics there is a risk of the host body falling into a septic state 6. However, the research indicating such potential pitfalls also states that the risk of sepsis with use of L. Rhamnosus should be considered against the risk of sepsis from other bacteria that would likely be defended against through use of L. Rhamnosus. In other words, L. Rhamnosus is regarded as being able to combat one of the only (RARE) pitfalls associated with probiotic use.
L.Rhamnosus Probiotic Supplements
Lactobacillus Rhamnosus is commonly found in probiotic supplements advertised to provide immune support, digestive support, and overall support for a more healthy-you. Frequently, L. Rhamnosus is found offered as part of a synergistic probiotic blend—containing several other varieties of transient and colonizing bacteria and yeast thought to provide health benefits.
A great example of one of these synergistic products is the Ther-Biotic Detoxification Support by Klaire Labs. This product contains Lactobacillus Rhamnosus, Bifidobacterium Bifidum, and Lactobacillus Casei, and is also the single most potent probiotic product I have ever taken. Klaire Labs has a long record of providing the most-potent probiotics on the market, and is trusted by many Integrated Doctors and Health Practitioners to address a wide variety of issues centered around the gastrointestinal tract.

As discussed above, L. Rhamnosus has been shown to be effective in the treatment of yeast overgrowth such as Candidiasis, caused by candida and other extremities of bacterial balance. It is these beneficial properties that have led to so many to regard Lactobacillus Rhamnosus as an effective probiotic supplement.
As with all supplements, there are considerable differences in quality, “inactive ingredients,” and viability of active ingredients. When conducting your search for the best probiotic supplement, there are a few guidelines that can help you come out on top. The first being the age-old adage; you get what you pay for. Don’t expect a $5.99 bottle of probiotics to be the best—and be wary of harmful fillers and inactive ingredients. The second, lesser-known rule of thumb when shopping for the best probiotic supplement is paying close-attention to the refrigeration requirements. Non-refrigerated probiotics tend to have a shorter life-span, and are often sold in a non-viable (dead) state. There is some mixed sentiment regarding the effectiveness of live cultures vs. dead cultures in the probiotics 7 world, but both sides of the argument seem to recognize that both forms are able to produce positive benefits. In my personal experience, I have found live culture probiotics to be much more robust in their effect on my physiological balance.
L. Rhamnosus … has been shown to provide notable benefits to neural pathways, the immune system, and in the treatment of candida.
There are many candida-cleanse packages that offer L. Rhamnosus on the ingredients list, but few products out there that offer isolated cultures of Lactobacillus Rhamnosus. ProBiotica Rhamnosus from Seeking Health, as well as Swanson Health Products both offer isolated cultures, but I have little experience with either brand, and can’t attest to their potency or viability. Klaire Labs Ther-Biotic Detox Support offers a semi-isolated blend of L. Rhamnosus which also contains Lactobacillus casei and Bifidobacterium Bifidum. Klaire labs are widely respected for the quality of their ingredients and especially for the viability of their probiotic strains. My personal experience is that this supplement is very potent and effective, although slightly difficult to obtain since it has to remain refrigerated during the shipping process.
Buying L. Rhamnosus Supplements
If you take supplements regularly for the treatment of a health condition, or just as a means to benefit your overall health, you’ve probably ordered supplements online before. While it’s nearly always a better idea to buy supplements from online retailers to ensure quality of brand and fairness of price, probiotics can sometimes be a bit of an issue. Probiotics often need to be kept in very controlled conditions, such as in the refrigerator, to ensure their potency (They are alive after all!) Most potent of the Lactobacillus probiotics fall into this category, making them a tricky sale for online retailers. Depending on the particular product, probiotics can be tricky to find online—often only available from unknown retailers. When it comes to Doctor Trusted Brands of probiotics, these can almost be impossible to find. Local stores carry some probiotics, but for supplements from doctor trusted brands you need to shop online, or get them through a licensed healthcare professional.

Probiotics are very powerful allies in the quest for maintaining optimal immune function and overall gut health. Lactobacillus Rhamnosus—L. Rhamnosus for short—is a particularly useful organism that has been shown to positively effect brain health, gut health, immune function, as well as serve as a powerful treatment for intestinal issues such as IBS. This supplement can be hard to find in local stores, and hard to order without having it spoil from online stores. Pureformulas is an excellent retailer that specializes in doctor trusted brands, and makes many accommodations to ship products while safeguarding against spoilage. If you are considering ordering a L.Rhamnosus probiotic supplement, they are definitely worth checking out. As with any health care decisions, you should seek the advice of a trained healthcare professional before making any decisions about your nutritional supplementation, dietary routines, or general shifts in lifestyle.
