Omega-3 (EPA/DHA)

Supplements

Mechanism

EPA and DHA incorporate into cell membrane phospholipids, modulating membrane fluidity and lipid raft signaling. EPA competitively inhibits arachidonic acid conversion via COX-2 and 5-LOX, reducing pro-inflammatory eicosanoids (PGE2, LTB4) while generating anti-inflammatory resolvins and protectins. DHA is critical for neuronal membrane integrity, modulating BDNF expression and synaptic plasticity via Nrf2 and NF-kB pathways.

Standard Dosing

2-4g combined EPA/DHA daily (targeting 2:1 EPA:DHA ratio for inflammation; 1:1 for cognitive)

Timing

With meals containing fat for absorption. Split dose AM/PM.

Cycle Duration

ongoing

Side Effects

  • Fishy burps/aftertaste
  • Mild GI upset
  • Loose stools at high doses
  • Potential increased LDL in some individuals

Contraindications

  • Active bleeding disorders
  • Scheduled surgery (discontinue 2 weeks prior)
  • Fish/shellfish allergy (use algal-derived)

Quercetin

Supplements

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
