Why Cod Liver Oil Is Ridiculously Useful

Opinions are always shifting on which health supplements are best but one perennial favourite is cod liver oil. So what’s the big deal?

It turns out that cod liver oil isn’t just Grandma’s favourite. It’s actually a vital supplement for healing our gut.

Essential Omega Fats

Why do we take any supplement? It’s because we believe it will give us a health boost of some kind.

That’s fine but we also need to think in terms of filling in the gaps in our diet.

Nutrients are like building blocks for the construction and maintenance of our bodies, and some building blocks are more fundamental than others.

Cod liver oil contains omega-3 and 6 essential fatty acids. Ever wondered why they’re called ‘essential’?

Some of the building blocks that our body needs can be manufactured inside us by combining other ingredients that are available.

But omega-3 and 6 essential fatty acids CANNOT be manufactured inside is. We can only get them from the stuff we eat.

So they’re not nice-to-haves, they’re musts, if we want our body to be upright and functioning every day, as opposed to lying down and feeling broken!

Raw Materials

Fatty acids are the building blocks of fats, and fats are very important inside our body. For example, every cell membrane, many hormones, some neurotransmitters and 60% of our brain are made of fat.

Our body uses omega-3 and 6 essential fatty acids to manufacture all other fatty acids that are needed to make these cell membranes, hormones and brain gunk.

From omega-3 the body makes two other particularly important fatty acids: EPA and DHA.

EPA and DHA are vital for brain, nerve and visual functions in the body. A deficiency in these nutrients may be one reason people with broken gut often also suffer from mental health conditions like depression, autism or dementia.

And here’s the kicker: our body needs certain vitamins in order to perform the alchemy of turning omega-3 into DHA and EPA.

Most people with broken gut aren’t getting enough of those vitamins – because their digestion is impaired – so the alchemy can’t happen.

This is where cod liver oil comes in. It’s an excellent source of EPA and DHA. So when we take a cod liver supplement, we know we’re giving our body essential fatty acids in the form our body can actually use them.

Can’t I Just Eat Fish?

If you have broken gut, eating fish isn’t going to be enough. You’re not going to be absorbing enough of the nutrients.

Why? We absorb fewer building blocks from any given mouthful of food if our gut’s not working properly. Our gut lining is inflamed, leaky and hardly working at its best.

That means it’s particularly important to supplement with cod liver oil if our gut’s malfunctioning. For those lucky folks whose guts are in tip-top condition, they can get enough omega-3 and 6 from diet alone.

Vitamin A

And there’s more good stuff going in cod liver oil. It contains sh*t-loads of vitamin A, one of the biggies for gut-healing! Vitamin A is particularly important for nerves and brain development. It’s also crucial for the health of our gut lining.

If we don’t have enough vitamin A, we can develop leaky gut. And if we already have leaky gut, it may be impossible for us to absorb enough vitamin A from the food we eat.

Yes, it can be a vicious cycle, where we don’t have the nutrients we need to heal our broken gut, and our broken gut can’t manufacture the nutrients our body needs to heal.

Cod liver oil contains a form of vitamin A that is particularly easy to digest for people with broken gut. Other forms of vitamin A that are used in supplements may not actually be absorbed at all.

Happily, cod liver oil also contains a good supply of vitamin D, another heavyweight of the vitamin world.

Recommended Products

Check out my recommended products and you’ll see one of my favourites is Green Pasture fermented cod liver oil. The fermentation process unlocks even more nutrients.

It’s also available in a version combined with grass-fed butter, as this mix has been found to be particularly beneficial.

Plant-Based Alternatives

For plant-based folks, I recommend a nut and seed oil, like Udo’s Oil.

The richest sources of omega-3 and 6 are in fact seed oils like flaxseed and hempseed oil. The only snag is that people with broken gut won’t be able to benefit fully from taking them (because they lack the vitamins needed to convert them to EPA and DHA, see above).

It’s interesting that gut-guru Dr Natasha Campbell McBride recommends that those of us struggling with chronic gut issues should supplement with BOTH cod liver oil AND a seed oil. Personally I follow that advice and take both every day.

By the way, seed oils are NOT FOR COOKING! They are very delicate and should be kept in the fridge, away from heat and bright light. They oxidise and become toxic when heated, even gently. Check out: Why Your Gut Is Broken

In case you’re wondering, coconut oil does not come in the category of seed oils and is excellent for cooking.

A Stupid-Simple Gut Remedy

Taking a cod liver oil supplement is a stupidly simple and effective way of helping our gut to heal.

It might be old-fashioned but many clinical studies show that taking omega-3 and 6 reduces inflammation and is effective in treating anything from infections and cancer to depression and diabetes.

Cod liver oil has also been shown in studies to boost our friendly bacteria, yay!

But remember, getting our diet right is even more important than the right supplements! Check out: Clean Eating: More Than Just An Elitist Fad

  1. Now I have learned more about the Omega Fats and Thanks a lot for the tips and insights! I think not all of us has a good grasp of the importance of it and I found your article useful.

  2. We could all use improvements to our health and it sounds like Cod Liver Oil is an easy way to accomplish this. I have issues with acid reflux. I wonder if this would help?

  3. I have heard that cod oil is really good for our gut as there were a lot of those supplements in the 90s. I don’t know if Japan has cod liver pills but I have to look.

  4. This is my first time learning about this, and really should try it out. I think I really need to work on bettering my gut health. Thank you so much!

  5. this is a very important article on supplement and the right kind of supplement. I think I will definitely agree with you on the importance of cod lever oils , however you have listed almost the entire spectrum of usefulness in a clear to understand lucid manner in your article

  6. This post brings back memory when I was living in my country of origin. My mom used to make me take cod liver oil a lot.

  7. Wow it’s amazing how taking cod liver oil consistently can help boost our immune system and most important of all, it can help in gut healing. I definitely learned a lot from this article when it comes to taking care of our health. Thank you!

  8. Yeah opinions have always been shifting on which health supplements are best or whether to have them or not. Being a nutritionist and a health coach, I do come across such queries quite often. I do recommend cod liver oil to my clients only when it is essential. Everyone doesn’t necessarily needs it. Though it is a vital supplement for healing our gut and is a good source of Essential Omega Fats.

  9. I often take cod liver oil, my mum swears by it! I love your blog, so informative and insightful. Great work and thanks for imparting some geeky knowledge my way yet again!

  10. Perfect! I now have aa reason to buy this one next time I go to the market. My wife is against it as she’s unfamiliar with Cod liver oil.

  11. blair villanueva

    Thanks for this useful information. I will check about cod liver oil and add to our regular diet meal.

  12. I’m a marathoner and I used to take Cod Liver Oil gel-cap (Kirkman). It was suggested by a family friend (who is a doctor), I was told that aside from omega-3 and 6 , it is also good for the muscles and has wound healing property. Thank you for this informative post!

    1. Thanks for the interesting article. Should the fermented version of cod liver oil be avoided if one has Candida/yeast overgrowth?

  13. I can only agree. I had/have an autoimmune disease, and the doctors didn’t know what to do. A combination of self-administered dietary change and OMEGA-3 completely reversed it, and I’m living symptom-free for years now. Nature always knows best.

  14. Eileen Mendoza Loya

    Fish oil or cod liver oil is a very good supplement to take everyday. It is great for eye health, skin and hair too.

  15. I grew up hearing horror stories about cod liver oil from the older people in the family. Although I take a good number of supplements, I really did not know a thing about cod liver oil, except that the people who grew up taking it thought it was akin to some kind of torture. I definitely need to check it out further though. I had no clue as to the benefits.

  16. I love the health benefits of cod liver oil I just wish it tasted better. Years ago my son took it all the time and it even helped his body heal a cavity in a baby tooth. Now that he is a teen he won’t touch the stuff.

  17. My gut is so broken from Hpylori and parasites. I now have histamines intolerance which makes healing the gut even harder. I get pain from eating so many food, it feels like an up hill challenge. I wish more gut experts had remedies for these issues. I right now my biggest challenge is trying to gain weight and find foods I can eat.

    1. I totally get that! I’m the same boat as you, i found colonics will clear out parasites impacted faeces and histamine build up, along with b12 shots and coffee enemas, its not easy but gaps works. Its hard once well not to slip back into old habits and let the bacteria rise up again, so i am embarking on the above again. I’d recommend health coach like here as its overwhelming and we always need help on these journeys.
