How to Choose
Choose Tributyrin Over Sodium Butyrate
Tributyrin is a triglyceride that protects butyrate through the stomach, delivering it to the colon where it is needed. Sodium butyrate releases immediately in the stomach, where most butyrate is absorbed before reaching target tissues. Tributyrin also eliminates the notoriously unpleasant rancid odor of free butyrate. CoreBiome is a patented tributyrin ingredient used in several quality products.
Effective Dose Range
Look for 300-1000mg tributyrin per daily serving. Most studies on butyrate gut health benefits used doses equivalent to 300-600mg tributyrin. Higher doses (750-1000mg) may be beneficial for post-antibiotic recovery or more significant gut barrier concerns. Start at the lower end and increase gradually.
How We Evaluate
Every product is scored against these weighted criteria. Our ratings reflect clinical evidence and product quality, not commission rates.
Butyrate Delivery Form
30%Tributyrin delivers butyrate to the colon where it benefits colonocytes. Sodium butyrate releases prematurely in the stomach. We strongly favor tributyrin-based products.
Dose Adequacy
25%Does the product provide a meaningful dose of tributyrin or butyrate per serving? Clinical relevance starts at 300mg tributyrin.
Third-Party Testing
20%Purity testing is important since butyrate supplements can contain impurities. NSF, USP, or independent lab verification is preferred.
Value
15%Cost per serving adjusted for form quality. A $0.80/serving tributyrin delivers more benefit than a $0.30/serving sodium butyrate.
User Experience
10%Smell, taste, capsule size, and GI tolerance. Tributyrin is far superior to sodium butyrate for odor and taste.
Frequently Asked Questions
What is the best butyrate supplement?
What is the best butyrate supplement?
The best butyrate supplement uses tributyrin rather than sodium butyrate for targeted colonic delivery. BodyBio Butyrate is the most established overall option. Avoid sodium butyrate products, which release butyrate prematurely in the stomach.
Is tributyrin the same as butyrate?
Is tributyrin the same as butyrate?
Tributyrin is a triglyceride (fat) that contains three butyrate molecules bound to a glycerol backbone. When it reaches the intestines, lipase enzymes release the butyrate. This delivery mechanism is what makes tributyrin superior to free butyrate salts — it protects butyrate from premature absorption in the stomach.
