The Omega-3 Brand That Actually Got the Science Right (And It's Family-Run)

I've taken omega-3 supplements on and off for years. I've bought the big bottles from warehouse clubs. I've tried the ones with the "extra pure" claims. And more than once, I've wondered whether any of it was actually doing anything — or whether I was just taking expensive fish oil capsules that were already oxidizing by the time I opened them.

Then I learned about Igennus. And I started asking better questions.

What Is Igennus?
Igennus is a UK-based, family-run nutrition supplement company founded in Cambridge in 2003. Their story starts with a personal one: founder Dr. Jav Nazemi had a relative with a serious heart condition, and his research into omega-3's clinical potential led him to create what became the UK's first ultra-pure EPA omega-3 supplement.

The company is now led by his daughter, CEO Mina Nazemi — and it remains genuinely family-run, with in-house nutrition scientists, a resident doctor, and a guiding philosophy that "good health should not be a luxury."

That philosophy shows up in how they price their products (fairly, for clinical-quality formulations), the forms they use (rTG — re-esterified triglyceride, the highest-absorption form of omega-3), and the research relationships they've built with academic and clinical institutions.

Did you know?Most omega-3 supplements use the ethyl ester (EE) form of fish oil — a synthetic form that's cheaper to produce but has lower bioavailability. Igennus uses the re-esterified triglyceride (rTG) form, which research shows is absorbed 70% more effectively than ethyl esters.

Igennus has a focused but comprehensive lineup built around omega-3 and broader nutritional support:

Pure & Essential Omega-3 Wild Fish Oil & Astaxanthin — £34.99 (3-month supply)

• What it is:Wild-caught fish oil in rTG form, paired with Astaxanthin (a powerful antioxidant carotenoid that also protects the omega-3 from oxidation)

• Why the Astaxanthin matters:Omega-3 is highly susceptible to oxidation — Astaxanthin in the same capsule protects the EPA and DHA from degrading

• Supply:180 softgels = 3 months; great value per dose

Super Concentrated Omega-3 Wild Fish Oil & Vitamin D3 — from £20.50

• What it is:High-concentration EPA and DHA in a once-daily format, paired with Vitamin D3

• Best for:People who want maximum omega-3 impact in a single capsule and who may be deficient in Vitamin D (very common in northern latitudes)

Vegan Omega-3 Algae Oil & Astaxanthin — listed

• What it is:Plant-based (algae-derived) omega-3 providing 400mg DHA + 200mg EPA

• Best for:Vegans and vegetarians who want the same clinical omega-3 quality without fish

• Important note:Algae is actually where fishgettheir omega-3 — this is the original source

Pharmepa COMPLETE — listed

• What it is:Combination of fish oil and evening primrose oil delivering 2000mg EPA and DHA

• Best for:People who need high-dose EPA support — often recommended in clinical contexts for mood, inflammation, and cardiovascular health

Vegepa PURE EPA — listed

• What it is:Ultra-pure EPA (eicosapentaenoic acid) combined with virgin evening primrose oil

• What makes it unique:Pure EPA (without DHA) has a specific profile of benefits for mood, focus, and inflammation that differs from combined EPA/DHA products

What Makes Igennus Different

I've looked at a lot of omega-3 brands. Here's what genuinely separates Igennus:

• rTG form for maximum absorption.This is a technical point that actually matters. The rTG form is absorbed significantly better than the ethyl ester form used in most mass-market fish oils. Bioavailability isn't just marketing language here — there's meaningful published research on this.

• GMP-certified EU/US manufacturing.Good Manufacturing Practice certification means the facility and process meet pharmaceutical-grade standards, not just supplement standards.

• In-house nutritionist support.Igennus employs nutrition scientists and a resident doctor who support customers directly. This is unusual for a consumer supplement brand and reflects the clinical heritage.

• Family-run and founder-led.The story of Dr. Nazemi creating the UK's first ultra-pure EPA supplement because of a family health event isn't a marketing narrative — it's the actual origin. That kind of motivated founding tends to produce companies that take quality seriously.

• Both fish and vegan formulations.The algae-based omega-3 line means Igennus serves the full spectrum of supplement consumers without compromising quality for either.

Igennus is a strong fit for:

• Middle-aged adults focused on long-term cardiovascular and brain health— omega-3's most evidence-backed benefits cluster around heart health, triglyceride levels, inflammation, and cognitive function

• Evidence-based supplement consumerswho have done their research and know the difference between ethyl ester and triglyceride forms of omega-3

• People with mood concerns— high-dose pure EPA has a growing body of research supporting mood and focus, and Vegepa is specifically designed for this application

• Vegans and vegetarianswho want clinical-quality omega-3 without compromising their diet

• UK and European consumerslooking for a domestic brand with clinical credibility — though Igennus ships internationally

Why We Love Igennus
Igennus represents something increasingly rare in the supplement industry: a brand that started from genuine scientific need, built with clinical rigor from the beginning, and didn't compromise when scaling up. The rTG formulation, the GMP manufacturing, the in-house science team — these aren't features bolted on for marketing. They're the foundation.

The Astaxanthin pairing in their flagship omega-3 is a perfect example of this thinking. Astaxanthin isn't just a bonus antioxidant — it protects the omega-3 from oxidizing in the capsule and after you take it. That's integrated, systems-level thinking about supplement efficacy, not just "throw in something that sounds good."

And the family story — a founder motivated by a relative's heart health, now led by the next generation — is the kind of continuity that tends to produce consistently excellent products.

Worth Noting

• Prices are in GBP.Igennus is UK-based and prices in British pounds. International customers should check current exchange rates and the Igennus website for shipping options and pricing.

• Clinical-quality supplements are an investment.Igennus products aren't the cheapest omega-3 on the shelf. That's because the formulation isn't the cheapest approach — it's the most bioavailable approach. The value calculation is different.

FAQ

Q: What's the difference between EPA and DHA, and which should I focus on?

A: EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) are both long-chain omega-3 fatty acids. DHA is critical for brain structure and development. EPA is more strongly associated with reducing inflammation and supporting mood. Most people benefit from both; people with specific mood or focus concerns may benefit from higher-EPA formulations like Vegepa.

Q: Why is rTG form better than ethyl ester omega-3?
A: Research shows rTG omega-3 is absorbed approximately 70% more effectively than the ethyl ester form. This means a lower dose of rTG can deliver the same (or greater) therapeutic effect as a higher dose of EE.

Q: Is Igennus third-party tested?
A: Yes — Igennus uses GMP-certified EU/US manufacturing, which includes third-party quality testing as a requirement of that certification.

Q: Do they ship internationally?
A: Igennus ships to multiple countries. Check igennus.com for current shipping destinations and international pricing.

Q: Are the algae-based products as effective as fish-derived omega-3?
A: Algae is the original source of EPA and DHA — fish accumulate it by eating algae. Igennus's vegan algae-based products deliver the same active omega-3 fatty acids, making them a genuinely comparable alternative for vegans.


Igennus is what omega-3 supplementation looks like when a family with a clinical research background builds a brand from the ground up around the science. The rTG formulation, GMP manufacturing, and in-house nutrition science team make this one of the most credible omega-3 brands available. If you're serious about the evidence behind your supplements, Igennus deserves to be in your routine.
