What Is Butyrate?
Butyrate is a short-chain fatty acid made from fermentation by specific gut bacteria. Unlike vitamins and minerals, the body does not get significant amounts of butyrate from food. Instead, it must rely on the gut microbiome to produce it.
Butyrate is the primary fuel source for the cells lining the colon. When these cells are well fed, the gut barrier remains intact. Without enough butyrate available, the barrier weakens, inflammation rises, and immune signaling becomes dysregulated.
How Butyrate Influences Health
- It maintains gut barrier integrity. By providing 70% of the energy colon cells need, butyrate prevents intestinal permeability (leaky gut) and maintains a physical shield against pathogens.
- Butyrate acts as a powerful immune modulator. It promotes regulatory T-cells and suppresses excessive inflammatory signaling. This explains why low butyrate levels are common in IBD and autoimmune conditions.
- Butyrate functions as a gene-signaling molecule and can influence genes involved in inflammation, cell repair, and metabolism. Current research is exploring the effect of butyrate on cancer prevention, neuroinflammation, and aging. Low butyrate levels are highly prevalent in individuals with Parkinson’s and Autism.
Despite its importance, many people produce far less butyrate than their bodies need due to fiber deficiency, loss of key microbes, and chronic inflammation. Antibiotic use also drastically decreases butyrate production.
How to Increase Butyrate
- Fermentable Fiber, such as Sunfiber® or inulin, leads to higher butyrate production.
- Visbiome® generates lactate and acetate, which other microbes can convert into butyrate through a process known as cross-feeding. Akkermansia strengthens the gut’s mucus layer, creating an environment where butyrate producers are more likely to thrive.
- Tributyrin & Sunbutyrate™ deliver butyrate directly to the gut. This can be especially helpful when inflammation is already present and microbial production is impaired.
- Anaerostipes is a primary producer of butyrate, and recent breakthroughs now allow for its direct supplementation.
