Pterostilbene

Supplements

Mechanism

Dimethylated analog of resveratrol with 4x greater oral bioavailability. Activates SIRT1 and AMPK, reduces oxidative stress, and improves lipid profiles. Superior pharmacokinetics compared to resveratrol due to methyl groups protecting against glucuronidation.

Contraindications

  • Hormone-sensitive conditions (mild estrogenic activity)

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
