Contemporary scientific research shows the predisposition of probiotics and healthy gut microbes to bolster the human gastrointestinal system.
In fact, having a healthy gut microbiome can protect against debilitating conditions, such as:
- Inflammatory bowel disease (IBD)
- Leaky gut syndrome
- Various forms of cancer
- Ulcerative colitis
- Gut dysbiosis
- Crohn’s disease
It would be absurd to assert that we understand every single thing about how microorganisms benefit humans.
Nevertheless, it’s safe to point out that modern research that is quickly furthering our knowledge of how these tiny lifeforms support our gut health.
Continue reading to find out everything about how which probiotics are best for the keto diet, and the research studies substantiating their health and longevity benefits.
The Best Keto Probiotics: What Research Has to Say
Not all probiotics are the same. In fact, the vast majority of modern probiotic supplements include bacterial species and microbes that are not beneficial for humans. Many probiotics include microorganisms that don’t survive when exposed to acidic environments.
When you take any sort of probiotic, it has to pass through some highly acidic regions in your stomach. As such, if the bacteria/microbes can’t withstand the acidity, they are useless for your gut.
Knowing that, here are the best keto diet probiotics that flourish in highly acidic conditions, according to science.
1. Lactobacillus acidophilus
Lactobacillus acidophilus is a lactic acid bacterium that organically flourishes in the small intestine. It is useful for treating lactose intolerance, Crohn’s disease, gut dysbiosis, and is extremely impervious to acidic environments.
Moreover, Lactobacillus acidophilus helps create vitamin B9 throughout the body.
2. Lactobacillus rhamnosus
Similar to the above probiotic, Lactobacillus rhamnosus is a lactic acid bacterium that colonizes the small intestine and is an essential regulator of the human immune system.
It also helps with digesting lactose by creating the enzyme lactase, along with synthesizing vitamins B9 and B12.
A scientific trial in healthy middle-aged and senior volunteers discovered that Lactobacillus rhamnosus supplements raised the relative activity level of natural killer (NK) leukocytes – which work to destroy tumor cells – by as much as 150%.
It’s crucial to mention that this anti-tumor effect seems to return back to baseline values shortly after time off of Lactobacillus rhamnosus supplements.
In other words: You attain the most benefit by using Lactobacillus rhamnosus daily as part of your keto diet probiotic regimen!
3. Bifidobacterium lactis
Bifidobacterium lactis is a bacterium that readily colonizes the gut. It receives high praise from clinicians thanks to its intrinsic resistance to bile salts (which is crucial for surviving the harsh digestive processes of the human gut).
Like Lactobacilli, Bifidobacteria help by digesting lactose and are also crucial for producing B vitamins.
4. Bifidobacterium infantis
In addition to vitamin synthesis, Bifidobacterium infantis is used extensively for stabilizing the gut microbiome and gastrointestinal function. It has been demonstrated to decrease the severity and frequency of Irritable Bowel Syndrome (IBS) symptoms.
Bifidobacterium infantis also contains a variety of enzymes that help us absorb various oligosaccharides. This benefits us since it breaks down otherwise indigestible nutrients. Similar to Bifidobacterium lactis, Bifidobacterium infantis is an excellent resistor of bile salts.
5. Lactobacillus paracasei
Lactobacillus paracasei is also part of our natural human gut microbiome. It is especially crucial as it digests fructooligosaccharides (FOS).
It has also been demonstrated to enhance immune function. In fact, it’s one of the probiotics utilized in the renowned healing treatment VSL #3 that is used to treat ulcerative colitis.
6. Bacillus coagulans
Bacillus coagulans has repeatedly been shown to enhance gastrointestinal system health, particularly helping those with Irritable Bowel Syndrome (IBS).
A scientific trial in patients with extremely crippling IBS revealed that Bacillus coagulans usage enhanced the quality of life ratings by more than 20%. It also decreased the frequency of bloating episodes by an astonishing 30-fold compared to placebo treatment.
Bacillus coagulans also reduced other common IBS symptoms, like nausea, frequent bowel movements, and lethargy significantly.
7. Saccharomyces boulardii
Saccharomyces boulardii is a nonpathogenic yeast that, when lyophilized, colonizes the gut and withstands bile salts. (An essential property considering that it has to surpass some extreme digestive conditions).
In contrast to bacteria, which make up 99% of human gut microbes, yeast comprises less than 1% of our gut flora. Saccharomyces boulardii is an especially advantageous keto diet probiotic (and also resists antibiotics, unlike bacteria).
In similar fashion to Lactobacillus rhamnosus, Saccharomyces boulardii is a hell of an immunomodulator. Scientific findings reveal Saccharomyces boulardii can effectively remedy chronic and acute health issues, such as:
- Antibiotic-induced diarrhea
- Traveler’s diarrhea
- Helicobacter pylori infection
- Irritable bowel syndrome
- HIV-related diarrhea
- Multiple parasitic infections
- Ulcerative colitis
- Crohn’s disease
The benefits of Saccharomyces boulardii do not stop there. Many research studies validate that this yeast substantially decreases oxidative stress and inflammation in the gastrointestinal tract of humans.
It also has significant protective effects by battling endotoxins, such as contaminant A from C. difficile and lipopolysaccharides from E.coli. Simply put, Saccharomyces boulardii is a yeast probiotic that you can benefit from in a multiplicity of ways.
Keto Probiotics for Optimizing Your Gut Health
It’s necessary to note that you don’t need probiotics for the keto diet, but these particular supplements can certainly help.
For the majority of people, keto diet probiotics are a great way to ensure you properly digest and absorb all the food you eat. This is especially true if your keto diet doesn’t contain much fiber or low-carb green vegetables.
Probiotics for the keto diet should include several (or all) of the microbial species that we discussed throughout this article.
You may also nourish your gut microbiome by eating certain prebiotic dietary fibers. You can read more about them checking out our Keto Diet Gut Health Benefits article!
We highly recommend using keto diet probiotics in conjunction with prebiotic dietary fibers.
