Omega-3 — Why Kiwis Should Care
Share
TL;DR
Omega-3 fish oil (high in EPA and DHA) is one of the most evidence-backed supplements in existence. Dr. Rhonda Patrick — one of the world’s leading micronutrient researchers — calls it her #1 recommendation. The science shows clear benefits for heart health, brain function, inflammation control, and healthy ageing. Most New Zealanders are not getting enough from diet alone. Here’s exactly why it matters, what the latest research says, and how to choose the right one.
Evidence rating for Omega-3 (High EPA/DHA): ⭐⭐⭐⭐⭐ Robust
(Multiple large RCTs, meta-analyses, systematic reviews, and consistent findings across cardiovascular, neurological, and inflammatory outcomes — one of the strongest evidence bases of any supplement.)
Why Dr. Rhonda Patrick Calls Omega-3 Her #1 Supplement
Dr. Rhonda Patrick, PhD (biomedical science, St. Jude / UCSD) has spent her career studying micronutrients and their impact on healthspan. In multiple appearances on the Joe Rogan Experience (including the landmark #1474 episode) and her own FoundMyFitness podcast, she repeatedly states that if she could only take one supplement, it would be high-quality fish oil rich in EPA and DHA.
Her reasoning is simple but powerful:
- Modern diets are chronically low in these long-chain omega-3s.
- EPA and DHA are not just “healthy fats” — they are structural components of every cell membrane, especially in the brain and heart.
- They powerfully modulate inflammation at the molecular level (resolvins and protectins).
- Decades of research show benefits that compound over a lifetime.
This isn’t hype. It’s the conclusion of a researcher who reads every study in detail.
The Evidence — What the Research Actually Shows
1. Cardiovascular Health (The Strongest Data)
The VITAL trial (Manson, J.E. et al., 2019, New England Journal of Medicine) followed 25,871 adults for over 5 years. While the primary endpoint for the omega-3 arm was not statistically significant for major cardiovascular events in the overall population, important secondary findings emerged:
- Significant reduction in heart attacks among participants with low baseline fish intake.
- Clear benefits for those already at higher cardiovascular risk.
A 2019 meta-analysis by Hu, Y. et al. (also NEJM context) and the 2020 Cochrane systematic review (Abdelhamid, A.S. et al.) both confirm:
High-certainty evidence that marine omega-3 supplementation reduces cardiovascular events and mortality, particularly in people with existing heart disease or high triglycerides.
Key takeaway for Kiwis: New Zealand has one of the higher rates of cardiovascular disease in the developed world. Many of us eat far less than the recommended 2–3 servings of fatty fish per week.
2. Brain Health & Cognitive Function
DHA makes up ~30% of the fatty acids in brain cell membranes. Low DHA status is linked to poorer cognitive performance and higher risk of neurodegenerative issues later in life.
Meta-analyses show benefits for: - Memory and executive function in older adults
- Mood support (especially when combined with EPA)
- Neuroprotection during ageing
Dr. Andrew Huberman frequently discusses omega-3 in his foundational protocol for exactly these reasons.
3. Inflammation & Recovery
Chronic low-grade inflammation drives most modern diseases. EPA and DHA produce specialised pro-resolving mediators (SPMs) that actively resolve inflammation rather than just suppressing it.
This is why athletes and high-stress individuals often report better recovery when supplementing.
NZ-Specific Context: Why Kiwis Should Pay Attention
Despite living in a country surrounded by ocean, most New Zealanders have suboptimal omega-3 status.
- Average fatty fish consumption in NZ is well below the 250–500 mg EPA+DHA daily target recommended by health authorities.
- The typical Kiwi diet (high in processed foods, seed oils, and grain-fed meat) is skewed toward omega-6, creating an unfavourable ratio.
- Local testing (NZ Nutrition Foundation and independent studies) shows many adults fall into the “low” or “very low” omega-3 index category (<4% RBC EPA+DHA — associated with higher cardiovascular risk).
Good news: New Zealand has excellent access to high-quality options. Brands like Clinicians, GO Healthy, and several premium imported lines (Nordic Naturals, Carlson, etc.) are widely available and often third-party tested. BioHackNZ only curates products that meet strict purity and potency standards.
Who Should Consider Omega-3 Supplementation?
Almost everyone who does not eat 2–3 servings of fatty fish (salmon, mackerel, sardines, anchovies) every week.
Particularly beneficial if you: - Have a family history of heart disease or high triglycerides
- Experience high stress or poor recovery
- Follow a plant-based or low-fish diet
- Are over 40 (age-related decline in conversion efficiency)
- Want to support long-term brain and heart healthspan
Who may not need it: People who already eat fatty fish 3+ times per week and have confirmed good omega-3 index via blood test.
Recommended Dosage (From Published Research)
| Goal | Combined EPA + DHA per day | Notes |
|---|---|---|
| Foundational / General health | 250–500 mg | Minimum effective dose for most adults |
| Cardiovascular support | 1,000–2,000 mg | VITAL trial & AHA recommendations |
| High triglycerides / inflammation | 2,000–4,000 mg | Under medical supervision |
| Cognitive / mood support | 1,000–2,000 mg | Higher EPA ratio often preferred |
Pro tip: Take with a meal containing fat for best absorption. Split dose morning/evening if >1 g total.
Always choose: Molecularly distilled + third-party tested for heavy metals, PCBs, and oxidation (TOTOX < 5 is excellent). Look for IFOS 5-star rated products when possible.
Safety & Interactions
Omega-3 fish oil is one of the safest supplements available when taken at recommended doses.
Possible considerations: - Mild blood-thinning effect — consult your doctor if you are on anticoagulants (e.g., warfarin, aspirin) or before surgery. - Fish allergy — choose algae-based DHA/EPA instead (vegan option, though slightly different profile). - High doses (>3 g/day) should only be taken under healthcare provider guidance.
No major safety concerns in the vast majority of published trials.
The Bottom Line — Dr. Rhonda Patrick’s Message
Dr. Patrick doesn’t sell supplements. She doesn’t have affiliate deals. When she says omega-3 is her #1 choice, it’s because the evidence is overwhelming and the risk is extremely low.
For New Zealanders who want to supplement with confidence — not guesswork — high-EPA/DHA fish oil is one of the highest-ROI additions you can make to your daily routine.
It’s not about living forever. It’s about giving your body the building blocks it needs to perform and recover at its best for as long as possible.
