"Marine oil" gets used as if it's one thing. It isn't. Fish oil, squalene, green-lipped mussel oil — they're different oils, from different sources, taken for different reasons. Here's the short version.
Fish oil = omega-3 fatty acids
Standard fish oil is taken for its omega-3s (EPA and DHA) — fatty acids your body can't make enough of on its own. If omega-3 intake is what you're after, fish oil is the tool for that job.
Squalene = a lipid your body already makes
Squalene is a different marine lipid entirely. Rather than supplying fatty acids you lack, it tops up a molecule your body already produces — squalene occurs naturally in human skin as part of your normal oil production. Deep-sea sharks are one of the richest natural sources, which is why shark squalene has been taken as a traditional daily oil for generations, particularly for skin health and everyday wellbeing.
So which one?
They're not competitors — they do different jobs. Plenty of people take both. The honest way to choose is by what you're actually after:
- Omega-3 intake (heart, brain, general nutrition basics) → a quality fish oil.
- Skin health and a traditional daily marine oil → squalene.
- Joint comfort → look at green-lipped mussel, a different marine extract again.
What matters more than the label on the front
Source and testing. Our Shark Squalene is purified and refined in New Zealand under HACCP and GMP quality systems, and every batch is laboratory tested before encapsulation — 1000mg per softgel, one a day.
