Quercetin vs Tributyrin (Butyrate Prodrug)

Mechanism

Quercetin is a flavonoid that inhibits mast cell degranulation and histamine release, functions as a potent senolytic (selectively clearing senescent cells) when combined with dasatinib or fisetin, and activates AMPK and SIRT1 pathways. It inhibits PI3K/Akt/mTOR signaling, suppresses NF-kB, and modulates JAK-STAT inflammatory cascades. As a zinc ionophore, it facilitates zinc entry into cells, which may inhibit viral RNA-dependent RNA polymerase.

Standard Dosing

500-1000mg daily

Timing

With meals for absorption. For senolytic effect: 3-day pulse monthly on empty stomach.

Cycle Duration

ongoing for general use; pulsed monthly for senolytic protocols

Side Effects

• Headache
• Mild GI upset
• Tingling extremities at high doses
• Rare: kidney toxicity at very high doses

Contraindications

• Pregnancy/lactation at high doses
• Concurrent cyclosporine therapy

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
