Butyrate is an important short-chain fatty acid (SCFA) that has been studied extensively in the past few decades, primarily due to its potent ability to modulate histone deacetylase (HDAC) activity and epigenetic regulation. Butyrate has become increasingly important in the cancer research field due to its potential to modulate the expression of cancer-related genes and pathways, as well as its ability to act as an anti-inflammatory and anti-carcinogenic agent. Butyrate is a four-carbon SCFA that is produced by the microbial fermentation of dietary fiber in the colon. It is then absorbed and utilized by the colonic epithelial cells for energy production and has been shown to have a number of beneficial effects on the human body, including acting as an anti-inflammatory and anti-carcinogenic agent.
Butyrate production is largely dependent on the composition of the gut microbiome.
Butyrate:
- can modulate histone deacetylase (HDAC) activity and epigenetic regulation
- can induce cell growth inhibition in different types of cancer cells.
- is anti-inflammatory {ref│ref│ref}
- is an immunomodulator {ref}
- SIRT3 inhibitor {ref}
- dictates ferroptosis sensitivity through FFAR2-mTOR signaling {study|study}
- preferentially induces apoptosis in glycolytic cells {ref}
- prevents anaerobic glycolysis and promotes normal oxidative glycolysis (epigenetically) {ref}
- is a modulator of redox signaling {ref}
- reduces endotoxin levels {ref│ref}
- reduces plasma glucose {ref}
- inhibits the growth of E. coli {ref}
- mitigates clinical and pathological features of C. difficile {ref}
- decreases the production of ammonia by inhibiting the growth of ammonia-producing bacteria e.g. H. pylori produces unusually large amounts of urea-derived ammonium
- GPR109A is a tumor suppressor in the mammary gland and the pharmacological induction of this gene in tumor tissues followed by its activation with agonists could be an effective therapeutic strategy to treat breast cancer. {ref}

CAUTION: Butyrate should not be used in oral squamous cell carcinoma {ref} as the receptor GPR109A is upregulated in this type of cancer. For the same reason, niacin should not be used in this cancer type.
Supplements and pharmaceutical drugs: Tributyrin (Butycaps) {ref}, Sodium/Calcium/Potassium/Magnesium Butyrate, Intrinsa Genoma Nutritionals (contains magnesium, butyric acid, caprylic acid🛈), Pendulum Glucose Control *, PhenylButyrate (link)
You can also increase butyrate by eating enough fiber (fruits and vegetables), type III resistant starch {ref}, short-chain fructo-oligosaccharides, xylo-oligosaccharides (XOS), herbs and herbal teas such as (green) tea {ref}, PHGG, senna {study}, licorice, ginger {study}, Triphala {ref}; honey, psyllium husk, berberine, orange juice {ref}, kombucha, coffee, chlorella, butter/ghee, taurine, curcumin, modified citrus pectin, kelp, walnuts {ref}, yacon, carrot, cooled potato, exercise, riboflavin {ref}
I wonder if it might be beneficial to do a one-time 7 day-course of a broad-spectrum antibiotic first and then start with the foods and supplements as mentioned above. Sort of a reset: out with the old, in with the new.
(*) What specific bacteria help create butyrate?
There are many species of bacteria that either contribute to the butyrate-making process or are responsible for the actual production of butyrate.
Some of the most common species who are responsible for producing butyrate:
- Faecalibacterium prausnitzii (belongs to Clostridium leptum cluster)
- Eubacterium rectale (belongs to Clostridium coccoides cluster)
- Roseburia spp. (Roseburia faecis, Roseburia inulinivorans, Roseburia intestinalis, and Roseburia hominis)
- Clostridium butyricum
- Clostridium beijerinckii
- Eubacterium spp. (Eubacterium hallii)
- Anaerostipes spp. (Anaerostipes butyraticus, Anaerostipes caccae, and Anaerostipes hadrus)
- Butyricicoccus pullicaecorum {study}
Additionally, species of bacteria in the Bifidobacterium genus are known to help break carry out the first steps in fiber digestion, providing molecules to the gut microbiome that the above species can use to make butyrate.
