tributyrin
Tributyrin is a triglyceride containing three molecules of butyrate, acting as a high-bioavailability prodrug of butyric acid. It functions as a histone deacetylase (HDAC) inhibitor and a primary energy source for colonocytes, widely used to support intestinal barrier integrity, modulate inflammation, and promote systemic metabolic health.
Lab Notes — Research Studies
01 Tributyrin administration improves intestinal development and health in pre-weaned dairy calves fed milk replacer
This study found that tributyrin improves intestinal immune and barrier functions while positively modulating gut microbial composition.
View Study ((PubMed))02 Dietary tributyrin, an HDAC inhibitor, promotes muscle growth through enhanced terminal differentiation of satellite cells
Research indicates tributyrin enhances the activity of muscle stem cells, leading to a significant increase in DNA:protein ratios and overall muscle growth efficiency.
View Study ((PubMed))03 Evaluation of tributyrin supplementation in milk replacer on diarrhoea occurrence in preweaning Holstein calves
Tributyrin supplementation was shown to significantly reduce the frequency and severity of neonatal diarrhea by strengthening the intestinal antioxidant barrier.
View Study ((PubMed))04 Dietary Tributyrin Attenuates Intestinal Inflammation, Enhances Mitochondrial Function, and Induces Mitophagy in Piglets Challenged with Diquat
Tributyrin reduced markers of inflammation (TNF-α, IL-6) and improved mitochondrial function and antioxidant capacity under oxidative stress.
View Study ((PubMed))05 Prophylactic tributyrin treatment mitigates chronic-binge ethanol-induced intestinal barrier and liver injury
Experimental evidence suggests tributyrin protects the gut lining and liver from damage caused by acute or chronic alcohol consumption.
View Study ((PubMed))06 Maternal tributyrin supplementation in late pregnancy and lactation improves offspring immunity, gut microbiota, and diarrhea rate in a sow model
Maternal supplementation improved the immune status and gut health of offspring, highlighting its systemic impact on microbiome development.

⚗️ Effects
- Superior Bioavailability: Unlike liquid butyrate which has a foul odor and low reach, tributyrin safely reaches the hindgut for maximum efficacy.
- Anti-Inflammatory: Consistently reduces pro-inflammatory cytokines like TNF-α and IL-6 in multiple animal models.
- Growth Promotion: Demonstrates clear improvements in average daily gain and feed efficiency in developing organisms.
- Alcohol Protection: Effectively mitigates intestinal and liver injury induced by ethanol consumption.
💉 Dosage & Administration
- General Gut Support: Research doses in large animal models often use 0.2% to 0.3% of total caloric intake.
- High-Dose Therapeutic: Human cancer trials have explored up to 400 mg/kg, though this is far above standard supplemental levels.
- Calf/Livestock Model: Common experimental doses range from 2g per liter of milk replacer to 8.3g per kg of feed.
- Prodrug Advantage: Because it is a prodrug, users can achieve higher systemic butyrate levels without the digestive distress of pure butyric acid.
⚠️ Side Effects
- Digestive Shift: Rapid changes in gut microbiota may cause temporary bloating or changes in bowel habits.
- Odor: Though less pungent than butyric acid, some concentrated forms can still have a distinct, slightly unpleasant smell.
- Metabolic Changes: High doses may influence lipid metabolism and gene expression in the liver.
- Unknown Long-term Human Data: Most current data is derived from animal models (porcine, bovine) or specific clinical cancer trials.
📦 Availability & Sourcing
- Supplement Form: Widely available as a specialized gut health supplement, often labeled as 'Liquid Butyrate' or 'CoreBiome'.
- Agricultural Roots: Historically used as a livestock feed additive before gaining popularity in the biohacking and longevity communities.
Reaction Log — User Experiences
Users and researchers are highly optimistic about tributyrin's potential as a 'biohack' for lifespan extension and neurological 'dekindling' via HDAC inhibition, though it is primarily recognized for its potent gut-healing properties.
