I hate disclaimers. I don’t feel like they should be necessary on an internet site, where people should be reluctant to believe anybody or anything. But, sometimes we’re gullible and vulnerable, especially when it comes to our health. So I just want to remind readers that I am not recommending Clostridium butyricum. I am not speaking against it either. What you put in your mouth is as personal as who you let French kiss you. Have caution. I do.
Do I think Clostridium butyricum sounds like a decent probiotic? On paper it does. But I’m aware that each person’s gut is unique beyond comprehension. Its function is as varied as each person’s diet, stress level, and sleep pattern. That’s pretty varied. Please never go out and buy or use a supplement because I mention it. I’d feel just horrible about that. Read the studies I reference. Read the internet anecdotes for the good AND THE BAD. Then, talk with your doctor about if he or she sees any harm for you based on what he or she knows about you.
Try hard to make your diet as real and whole as you realistically can. That’s a great start for health! And also try hard to savor each person you love in your life. Our life on Earth really is unpredictable, and each moment counts. For more on Clostridium butyricum on my site, read here, here, and here. I’ve enjoyed searching for information about it and putting it in one “place.” I hope if you’re reading this far, you find what you’re searching for. If you can’t understand something, please ask.
Clostridium butyricum For Vascular Dementia
In a vascular model of disease, mice with carotid artery occlusion who were given Clostridium butyricum (strain WZMC1016 dosed at 5 x 10 ^6, 5 x 10^7, 5 X 10^8) had improved cognitive test scores.
In humans, this might translate into someone who has vascular dementia from atherosclerosis—“clogged arteries.” The probiotic-treated mice fared significantly better on motor skills testing and cognitive skills testing (numerically significant at the two higher doses). Their brains looked better in the hippocampal region, a region known to be exceptionally sensitive to low blood flow, than the non-treated vascular occlusion subjects. Please notice that dose did affect the outcome!
The specifics, if you’re interested, also indicated that the probiotic treated mice had:
- Increased levels of BDNF (brain-derived neurotrophic factor)
- Increased ratio of Bcl-2 to BAX (antiapoptotic to proapoptotic factors) (10^7, 10^8 doses)
- Increased ratio of p-Akt/Akt (Akt phosphorylation=p-Akt) (5×10^7, 5×10^8 doses)
- Structural preservation of the hippocampus with reduced apoptosis of neurons in the hippocampus (dose of 5 x 10^8)
- Increased butyrate in the feces
- Increased butyrate in the brain (10^7, 10^8 doses)
- Increased diversity of GI bacteria (“drastically changed” were the words) (10^7, 10^8 doses).

Clostridium butyricum for Stroke
In a mouse study which simulated cerebral ischemia/reperfusion injuries, such as those which may be found in a stroke in humans, mice who were pretreated with Clostridium butyricum (strain WZMC1018 at 1 x 10^9 dose) had less neurological deficits than the other mice.
In addition, in the probiotic treated mice it was found that:
- The expression of Caspase-3 and Bax were significantly decreased
- The Bcl-2/Bax ratio was significantly increased
- Butyrate content in the brain was significantly increased
- Apoptosis in the hippocampus was ameliorated
- Decreased contents of MDA; increased SOD in the brain tissue.

Clostridium butyricum in Traumatic Brain Injury
In a traumatic brain injury model, Clostridium butyricum administration in mice resulted in improved outcomes.
Specifically found were:
- Improved neurological deficits
- Decreased brain edema
- Less impairment in the blood brain barrier
- Increased GLP-1 production in colon and increased GLP-1 receptor protein expression in the brain (GLP-1 is glucagon-like peptide-1 and is considered a mediator between the gut and the brain.)
- An improved intestinal barrier, evidenced by decreased serum D-lactate levels.

Clostridium butyricum for Prevention of Anxiety
Laryngeal cancer patients who required surgery (laryngectomy) had lower anxiety parameters when they received Clostridium butyricum before surgery.
Human laryngeal cancer patients received Clostridium butyricum (420 mg/capsule, two capsules twice a day) prior to surgery for about 14 days. When compared to placebo-receiving laryngeal cancer surgical patients, they had:
- Lower corticotropin-releasing factor levels (CRF), a stress-related hormone, also commonly known as corticotropin-releasing hormone (CRH)
- Lower morning and evening heart rates
- Lower anxiety test scores.

Clostridium butyricum for Bladder Cancer and Colon Cancer
The association of Clostridia affecting cancer goes back to 1813, when it was noted that patients who acquired gas gangrene (Clostridium perfringens infection) had cancer regression! Because they are anaerobic organisms, they emerge from spore form to vegetative form in the anaerobic, necrotic centers of tumors, where the bacteria can promote tumor destruction. (1)
An in vitro and in vivo mouse study showed that Clostridium butyricum induced bladder cancer tumor cell death (apoptosis).
Rather than oral administration, Clostridium butyricum (both in the in vitro and in vivo arms) was directly applied to the tumor cells. The study found the administration:
- Increased TRAIL (tumor necrosis factor-related apoptosis-inducing ligand ) release from polymorphonuclear leukocytes (PMNs), perhaps more effectively and safely than the current therapy, BCG
- Drastically suppressed growth of bladder cancer cells in vitro and in vivo.

In a colon cancer model study, researchers found that Bacillus subtilis and Clostridium butyricum inhibited proliferation of colorectal cancer cells and promoted cancer cell apoptosis in vitro and in vivo.
Mice with induced colon cancer were used for the in vivo study, and human colon cancer cells used for the in vitro study. The researchers noted improved inflammatory markers and immune responses.
- TLR4 mRNA was decreased with the probiotic administration.
- NfKb was also decreased with the administration of the probiotics.
- The probiotic treated cancer-model mice had downregulation of Th17 cells as compared to the non-treated cancer mice.

Clostridium butyricum to reduce food allergy (milk allergy)
Clostridium butyricum reduced intestinal anaphylaxis to beta-lactoglobulin in mice with induced allergy and the researchers felt the probiotic might have potential as a supplemental therapy for food allergy.
Mice who had a milk allergy to beta-lactoglobulin were given Clostridium butyricum. When given the probiotic, the treated mice, as compared to the untreated mice, had:
- Decreased diarrhea
- Improved villus histological integrity with decreased amount of inflammatory cells [It really was pretty cool if you like histology.]
- Increased CD4+ CD25+ Foxp3+ Treg cells in the MLN and high levels of TGF-β and IL-10 in the serum
- High levels of TGF-β and IL-10 in the serum
- Reversed imbalance of Th1/Th2 andTh17/Treg.

Closing and Personal Anecdote
I think that’s all the studies I’ll go through on Clostridium butyricum for a while. My eyes were kind of drooping near the end. Make sure and comment on typos or wrong information so I can address them!
I did try this probiotic several times off and on over the last couple of years at all kinds of doses. I had no major issues from it when I took it, but I did have some minor ones. (But my gut is not your gut.) Despite this probiotic reportedly being used for constipation in Asia, I found that my baseline constipation increased and I had to increase my magnesium laxative use while taking it. I also experienced bloating. I had a good sense of well-being on the probiotic, but I have a tendency to have that much of the time anyhow. I seemed to wake up earlier, but I think that could be anything. Due to the constipation and (painless but pretty significant) bloating, I could never extend my use of this probiotic more than two weeks. I didn’t know if it was the probiotic itself or the lactose in it.
That’s it for today.
