Imagine: you faithfully take your omega-3 supplement, thinking you're doing well… but did you know that much fish oil – especially the cheaper varieties – comes from residual streams of the fish industry? To make the oil suitable for consumption, it is often deodorized, decolorized, and heated. This processing can lead to (partial) oxidation, producing free radicals that may promote inflammatory processes in the body.

Of course, not every fish oil is automatically "bad," and there is also higher quality fish oil. But it remains basically a processed product mainly aimed at isolating the omega-3 fatty acids (EPA and DHA).

Differences at a glance

Why this nuance?

• Quality varies: Not all fish oil is the same. High-quality brands pay a lot of attention to careful extraction, packaging, and storage to minimize oxidation.
• Processing vs. whole food: Cod liver oil is generally less processed and contains multiple essential nutrients in addition to omega-3.
• Personal preference: Choose what is feasible and pleasant for you, and pay attention to both quality and dosage. Some people tolerate cod liver oil better and prefer that it has a "broader" nutrient profile, while others prefer a specific (or higher) dose of omega-3 from fish oil.

Ultimately, it is important to make a well-considered choice with your supplement selection. Omega-3 fatty acids can certainly contribute to good health, but pay attention to the source, processing method, and the presence of other valuable nutrients.

Why fermented cod liver oil is better than fish oil

Our great-grandparents were not fans of factory-made products. They fermented cod livers in saltwater – a slow, natural process where the oil gently releases. No heat, no chemicals, no tricks. Just Mother Nature doing her work. If you want a bit more depth on the question cod liver oil or fish oil, read more about it here!

Why fermentation is so brilliant:

• Preservation of all vitamins: Research shows that fermented cod liver oil contains higher levels of natural antioxidants and vitamins compared to refined variants. A, D, E and K2 (which forms during fermentation!) – a dream team for your bones, immune system, and hormones.

• Omega-3 in pure form: No oxidation, because no heating. This keeps EPA and DHA intact.

• Sustainability: No waste – everything from the fish is used.

Fun fact: The Vikings already used this!

Green Pasture vs. Regular Cod Liver Oil: The difference that matters

Not all cod liver oil is the same. Many brands heat the oil, causing vitamins to be lost and synthetic variants to be added. But Green Pasture? They do it differently:

• Wild-caught cod from clean waters.
  
• Fermentation without junk: No chemicals, just time and patience.
  
• Combo with butter oil: Although K2 is not explicitly mentioned in the sources, the combination with butter oil (rich in K2) in Green Pasture products emphasizes the role of fat-soluble vitamins for bone health and calcium metabolism 

But Gino, I don't like fish! No stress – the natural variant is mild, and you can mix it with a splash of honey or cocoa. (Psst: kids often swallow it easier than we do 😉)

How much Cod Liver Oil do you need? 🥄

FAQ: Everything You Want to Know (But Never Dared to Ask)

1. Is Cod Liver Oil safe for children?
Absolutely! Traditionally, children were given cod liver oil for strong bones and fewer ear infections. Choose the natural variant – sweetness is an acquired taste 😉.

2. Why that K2?
Vitamin K2 directs calcium to your bones, not your arteries. A must for everyone supplementing with D3.

3. What does Cod Liver Oil taste like?
Honestly? A bit fishy. But with a spoonful of raw honey or in a smoothie with banana and cocoa, you hardly taste it. Pro tip: Hold your nose while swallowing – always works! 🤫
