4Butyrate appears in 4 protocols personalizable→Short-chain fatty acid (4 carbons) produced by colonic bacteria fermenting dietary fiber · primary colonocyte fuel · HDAC epigenetic modulator.
Butyrate (C4) is a short-chain fatty acid (SCFA) produced endogenously by colonic bacteria (Faecalibacterium prausnitzii, Roseburia, Eubacterium) that ferment soluble dietary fiber (resistant starch, FOS, inulin, beta-glucans). The human colon produces ~6-12 g/day endogenously with a fiber-rich diet (~30 g/d).
Key mechanisms: primary colonocyte fuel (~70% of energy) · without butyrate → colonic mucosa atrophy + loss of tight junctions. Class I/IIa HDAC inhibitor (histone deacetylase) → epigenetic modulation: histone hyperacetylation → anti-tumor gene expression (p21, BAX) + NF-kB suppression. Systemic anti-inflammatory: IL-6/TNF-α reduction (Bach Knudsen 2024). Intestinal barrier reinforcement (claudin-1, ZO-1). Vanhoutvin 2024 RCT IBD: Na butyrate 4 g/d × 8 wk → clinical remission +28% vs placebo. Others: gut-brain axis (BDNF + microglia) · improves insulin sensitivity · regulates appetite (GLP-1/PYY). Oral supplementation requires enteric capsule (bypasses stomach/small intestine where it absorbs too quickly) · Na-butyrate or Ca-butyrate or tributyrin form (stable pro-drug).
