The Science of Purity: Why Our Fish Oils Laugh in the Face of Industry Standards
Let’s be perfectly clear about our process. We start with nature — the vast, powerful ocean — and then we apply a rather obsessive level of science to perfect it. It’s a journey from the raw potential of the sea to a final, purified supplement that is, quite simply, unparalleled.
While some brands might be vague about their manufacturing, we’re an open book. All our fish oils are produced in UK factories adhering to what’s known as Good Manufacturing Practice (GMP). For us, that isn’t a goal; it’s the absolute baseline. We employ a state-of-the-art purification process — a multi-stage molecular distillation, if you must know — that targets and removes unwanted elements with surgical precision. The result? A level of quality assurance that, frankly, others can only dream of.
Sustainability Isn’t a Buzzword, It’s a Prerequisite
You’ll hear a lot about ‘responsible sourcing’. For some, it’s a marketing tactic. For us, it’s a non-negotiable scientific and ethical principle. We don’t just hope our fish are sourced responsibly; we have the certification to prove it.
Our fish oil range is certified by ‘Friend of the Sea’, the leading global authority on sustainable seafood. This isn’t some certificate you buy online. It means independent auditors have scrutinised our entire supply chain, from the fishery to the factory, against their formidable criteria. This certification is your guarantee that our product is free from the lazy, irresponsible practices that can plague the industry: no overfishing, no bycatch of endangered species, and absolutely no illegal, unreported, or unregulated (IUU) fish. Frankly, we welcome the scrutiny.
Purity So Extreme, It Makes Regulatory Standards Look Quaint
It’s an unfortunate scientific truth that our oceans are not the pristine environments they once were. Pollutants are a fact of life. This is where some fish oil brands are content to just scrape by, meeting the bare minimum safety levels set by authorities. We find that… unambitious.
The European Commission (EC) sets “permitted safe levels” for contaminants like PCBs, dioxins, and mercury. And yes, of course, our oils are well below them. That’s table stakes. Then there’s the Global Organisation for EPA and DHA Omega 3s (GOED), an organisation that sets even stricter global standards for quality. We surpass those, too. Naturally.
But here’s where we really part ways with the pack, and you might want to pay attention. EC legislation requires testing for a mere 6 chemical constituents. Six. We find that insultingly inadequate. That’s why our oils are routinely tested for 209.

Yes, you read that correctly. Two hundred and nine. Is it overkill? Perhaps. But when it comes to the purity of what you put in your body, we believe ‘overkill’ is the only acceptable level of diligence. As our analysis shows, our purity levels aren’t just ‘within’ the limits; they render the limits practically irrelevant.
Please note: Our unwavering commitment to the Friend of the Sea standard applies across our fish oil range, with the sole exception of our Cod Liver Oil 1000mg, which follows its own rigorous sourcing protocol.
Still Have Questions? We’d Be Surprised if You Didn’t.
We’ve just thrown a lot of science at you, and our passion for the details can sometimes get the better of us. We get it. That’s precisely why our expert Nutrition Advisors are on hand. They live and breathe this stuff. Challenge them. Grill them on molecular distillation or the specifics of GOED standards. They love it.
