Butyrate

Butyrate is a short-chain fatty acid (SCFA) produced by gut bacteria fermenting dietary fiber. It is the primary energy source for colon cells, supports gut barrier integrity, and acts as a histone deacetylase (HDAC) inhibitor, which has epigenetic implications for gene expression. Its healthspan relevance lies in its ability to reduce systemic inflammation, improve metabolic health, and maintain a healthy gut microbiome, a key pillar of longevity.

Verdict

A valuable tool for gut health, best achieved through dietary fiber.

Protocol

• Typical daily dosages range from 300 mg to 2000 mg, often taken with meals to support gut health.

Flags

• Increasing dietary fiber is the primary and often superior method for raising butyrate levels.
• Supplements have a very strong and distinct, often unpleasant, odor.
• High doses may cause bloating, gas, or other gastrointestinal discomfort.
• The benefits of direct supplementation versus endogenous production via fiber are still debated.
