Omega-3 (EPA/DHA) for longevity

At a Glance

Mechanism of Action

Incorporated into membrane phospholipids; precursors to resolvins and protectins; lower hepatic triglyceride synthesis.

Omega-3 (EPA/DHA) is typically taken orally as triglyceride-form fish oil or algal dha, with largest meal. Incorporated into membrane phospholipids; precursors to resolvins and protectins; lower hepatic triglyceride synthesis. Effective range is 1–4 g, with 2 g EPA/DHA combined being the most-studied dose. Taking it with food improves absorption and reduces GI upset.

Dosage & Timing

Timing (With largest meal) is chosen to match the compound's pharmacokinetics and the physiological pathway it targets. Consistency matters more than the exact hour.

How to Take

1. Start at the lower end of the range (1) for the first 7–10 days to gauge tolerance.
2. Titrate up to the target dose of 2 g EPA/DHA combined once tolerance is confirmed.
3. Take with a meal that contains fat for optimal absorption.
4. Best timing: With largest meal. Keep the daily window consistent so effects are legible against baseline.
5. Missed dose: skip and resume normally; never double up.

Absorption & Bioavailability

• Fat-soluble — take with a meal containing ≥10 g of fat to maximise absorption.

Cycling & Stacking Strategy

• Most users run Omega-3 (EPA/DHA) continuously and reassess every 12 weeks with bloods and a symptom log.
• If effect plateaus, a 2–4 week wash-out often restores responsiveness by resetting receptor sensitivity and feedback loops.
• Common stack: Vitamin D3, Astaxanthin. Introduce one addition at a time so you can attribute effect and side effect.
• Rotate related supplements seasonally rather than layering five products in the same category.

Safety Profile

How to Choose a Quality Product

• Third-party tested — look for NSF, Informed Sport, USP or an equivalent independent COA (certificate of analysis) on the batch you're buying.
• Standardised active — the label should specify the exact active compound and its concentration, not just the botanical name.
• Minimal excipients — avoid unnecessary fillers, artificial colours and shared allergens (soy, gluten) unless you're happy to test for reactions.
• Dose per serving matches the researched range (1–4 g) — many consumer products under-dose to widen margins.
• Manufactured in a cGMP-certified facility with a clear country of origin.
• Reasonable price per effective dose — cheaper products often deliver less active per capsule, so the true cost-per-dose is higher.

Common Mistakes

• Under-dosing — using 1 when the research uses 2 g EPA/DHA combined.
• Stopping after two weeks — most longevity-relevant endpoints need 8–12 weeks of consistent dosing before they move on bloods.
• No baseline labs, so any effect is attributed to placebo or hype rather than to the supplement.
• Stacking three or four new products in the same month — you lose all ability to attribute results.
• Buying the cheapest brand and skipping the third-party COA — potency and purity vary dramatically between manufacturers.
• Taking it fasted despite a fat-soluble or food-dependent absorption profile.

Evidence Grade — A (91/100)

Grade A — multiple randomised human trials or meta-analyses support the primary claim. Dosing, mechanism and safety are well characterised in humans.

The primary references used to grade Omega-3 (EPA/DHA) are listed below. Cross-check against the current literature and expect the grade to move as new human trials publish.
