Cod liver oil or omega-3 – which one is the best for me (and can I take both at the same time)?

It is best to take only cod liver oil supplement.

Both contain omega-3 fatty acids. Cod liver oil is richer in nutrients and contains vitamins A and D. 1 teaspoon (that is about 5 ml.) contains 4501IU * (90% RDI) Vitamin A and 450IU * Vitamin D (113% RDI).

More bang for your buck.

If you do not want more vitamin A (vitamin A overdose is harmful) and D or if you want to strictly control their dosage, take only fish oil. You can also take fish oil in addition to vitamin D and A supplements if you want the benefits from those vitamins but don’t want to take cod liver oil.

Important: If you are pregnant, avoid cod liver oil. Overdosing can lead to birth defects! Play it safe and take your doses of DHA and EPA from Omega-3 supplement.

Bet on UK-made pure oil supplements certified for quality and, most importantly, with good reviews from people just like you

I have selected the best cod liver supplements in the UK having in mind these criteria…

  • Origin. Look for oil from fish that is caught using sustainable methods and comes from ecologically clean areas. The origin of most supplements is the wild fish from the icy waters of the Arctic or Norway.
  • Purified from heavy metals. All products are clean of metals and other contaminants.
  • Made in the UK. We support British business. If the product is made in the UK, this is a bonus for us.
  • Certified quality. We have selected products that have been independently tested for quality, taste, etc. Some products have even won prizes for their taste (product number 5). We want only the best.
  • Customer feedback. What matters to me is what people say about the product, and not what the manufacturer says. I have selected only highly-rated products on Amazon, etc.

OK, let’s move on to the list with the best cod liver oil supplements…

Fermented Cod Liver Oil is a product made after soaking the cod liver in brine. After fermentation, the oil that rises to the surface of the water is collected, purified, and packaged.

Why fermented cod liver oil? Simply put, fermentation enhances the nutritional value of the product.

What is the best time to take cod liver oil capsules and what is the recommended dose?

It is best to take it in the evening with something fatty – meat, fish, salad with olive oil, etc.

Cod liver oil is fat, and it is best absorbed with other fats. It is best to take 1-3 tablets at dinner. There is a very good article (studies are also mentioned) why you should take such supplements at night here –

By the way, it is best to keep cod liver oil in the refrigerator. It doesn’t matter if it is in the form of capsules or liquid.


OK, what about the recommended daily dosage (RDI)?

There is no standard.

You need to consider what dosage brings you results (whatever they may be), the doctor’s recommendations, and to read the labels. Use as a guide the recommended doses of the products in the list above. This is most often 1 -3 tablets/day. Stick to the labels and everything (should) be OK.

Note: Be careful with the dose of vitamin A! Consider the intake of the vitamin from your diet plus other supplements (if you take any) and try not to exceed the recommended dose. As I said, if you overdo it, it becomes toxic.


If you can’t get enough vitamin A, D, or omega-3 fatty acids from your diet, use some of the best cod liver oil supplements from the list above

They contain 100% of the recommended daily doses of vitamins A and D. They have EPA and DHA. The taste is… bearable. They are easily and quickly swallowed. Take it in the evening with fatty foods. Take a walk in the sun, eat foods rich in calcium and you will be fine.
