Standard Dose
Timing
Cycle Duration
Evidence LevelStrongModerate

Mechanism

Endocannabinoid-like lipid that activates PPAR-alpha and indirectly enhances endocannabinoid tone. Potent anti-inflammatory and analgesic without acting directly on CB1/CB2. Reduces mast cell activation, neuroinflammation, and chronic pain.

Contraindications

  • None established at standard doses

Mechanism

Tributyrin is a triglyceride form of butyrate — a short-chain fatty acid critical for colonocyte health. HDAC inhibitor that supports gut barrier integrity, reduces intestinal inflammation, and modulates immune function. Superior absorption compared to sodium butyrate.

Contraindications

  • None established at standard doses
