Butyrate (Sodium Butyrate / Tributyrin)
A short-chain fatty acid (SCFA) that is the primary energy source for colonocytes. Produced by gut bacteria from fiber fermentation, supplemental butyrate supports intestinal barrier integrity, reduces inflammation, and promotes healthy gut microbiome composition.
How it works
Inhibits histone deacetylases (HDACs) for anti-inflammatory gene expression. Fuels colonocyte mitochondria via beta-oxidation. Strengthens tight junctions by upregulating claudin-1 and ZO-1. Activates GPR109A to suppress NF-κB.
Key facts
- Molecular weight: 110.09 Da (sodium butyrate)
- Half-life: ~30-40 minutes (rapidly metabolized by colonocytes)
- Bioavailability: Tributyrin: ~60-80% delivery to colon; sodium butyrate: variable
- Storage: Room temperature. Sealed container (pungent odor if exposed).
Dosing overview
- Typical dose: 300-600 mg tributyrin or 500-2000 mg sodium butyrate
- Frequency: 2-3x daily with meals
- Duration: Ongoing
- Route: Oral (enteric-coated or tributyrin pro-drug)
Reported benefits
- Colonocyte energy support
- Tight junction integrity
- Reduced GI inflammation
- Healthy microbiome support
- Epigenetic modulation (HDAC inhibition)
- Improved insulin sensitivity
Possible side effects
- GI gas/bloating
- Unpleasant taste/odor (sodium butyrate)
- Loose stools initially
- Rare: heartburn
Research
- Butyrate and intestinal barrier function (2021): Supplemental butyrate increased transepithelial resistance by 45% and reduced endotoxin translocation in human gut models.
- Tributyrin in ulcerative colitis (2022): 4-week tributyrin supplementation reduced fecal calprotectin by 60% and improved clinical remission rates in mild-moderate UC.
Community reviews of Butyrate
- vial_vault_vicky rated it 5/5 - Solid compound with real results: Been using Butyrate for about 6 months and the results are clear. Not overnight dramatic, but a steady, consistent improvement that became undeniable by the end of the first month. The mechanism makes sense based on what I have read in the literature, and my subjective experience matches the expected timeline. Benefits built gradually and plateaued at a good level. Side effects were minimal to none at the dose I used. Followed proper protocols for sourcing, storage, and administration. Would recommend to others who have done their research and have realistic expectations.
- morning_protocol rated it 4/5 - Worth adding to the protocol: Butyrate has been a worthwhile addition. I am data-driven and tracked relevant markers before, during, and after. The improvement is measurable and correlates with the intervention timeline. What sets this apart from some compounds I have tried is the consistency. Benefits did not fluctuate wildly or disappear. They built up and maintained. That gives me confidence in the mechanism. Tolerance has been excellent. Nothing in my bloodwork or subjective experience raised any flags. This is the kind of compound that does its job quietly without causing problems. Exactly what you want.
- cycling_chad rated it 5/5 - Genuinely effective after 3 months: Been using Butyrate for about 3 months and the results are clear. Not overnight dramatic, but a steady, consistent improvement that became undeniable by the end of the first month. The mechanism makes sense based on what I have read in the literature, and my subjective experience matches the expected timeline. Benefits built gradually and plateaued at a good level. Side effects were minimal to none at the dose I used. Followed proper protocols for sourcing, storage, and administration. Would recommend to others who have done their research and have realistic expectations.
- protocol_pete rated it 5/5 - Noticed clear benefits within weeks: Added Butyrate to my protocol about 1 month ago and it has earned its place. The benefits became noticeable around week 2-3 and have been consistent since. What I appreciate about this compound is the predictability. It does what the research suggests it should do, at roughly the timeline you would expect. No surprises, no dramatic swings, just steady improvement. No notable side effects to report at my dose. Sourcing is always the challenge with research compounds, insist on third-party testing. Storage and reconstitution per standard protocols. Plan to continue.
- lifter_cole rated it 5/5 - Butyrate calmed my gut faster than I expected: I ran sodium butyrate for about 6 weeks while juggling teaching, coaching, and my own training, and it made a noticeable difference for me. My gut felt less irritated, especially on busy days when meals were a bit off and stress was up. Bowel stuff was just more settled, less random and annoying, which honestly made a big difference to how I felt day to day. Could be it suited me well, but I was pretty chuffed with it. For my own experience, it was one of the few gut health things that actually seemed to do something useful.
- scientist411 rated it 4/5 - Helpful, but I still kept my sceptical hat on: I tried sodium butyrate for about 4 months because as a Netherlands-based ultrarunner my gut is often the weak link, especially with long sessions and lots of carbs. I went in sceptical, and that did not fully change, but my belly felt a bit calmer and more predictable, so I kept it.
