Cod Liver Oil: Frequently asked questions

What types of Cod Liver Oil are there and what determines a good product?

There are many different types of Cod Liver Oil, but the most common one is a combination of fish liver oil and cod liver oil. This type contains both EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). It also has vitamins A & D added to it. The other type is pure cod liver oil that does not contain any fish oils or vitamin additives at all. Some people prefer this because they believe that adding additional ingredients makes the product less effective for them personally since their body may be unable to absorb some nutrients from these extra ingredients in addition to what’s already present in the supplement itself. However, there are no scientific studies showing which form works better than another so you should try each kind out yourself if possible before deciding on your favorite brand.

The quality of a Cod Liver Oil is determined by the amount and ratio of Omega 3 to 6 fatty acids. This can be measured using Gas Chromatography (GC). A good oil will have at least 1000mg EPA/DHA per serving, with no more than 2% GLA or less than 1% LA content.

Who should use a Cod Liver Oil?

Anyone who is interested in improving their health and wellness. Cod Liver Oil has been used for centuries to support the immune system, help with skin conditions such as eczema or psoriasis, improve joint function and reduce inflammation. It can also be taken by people suffering from chronic fatigue syndrome (CFS), fibromyalgia and other autoimmune diseases like rheumatoid arthritis or lupus erythematosis.

Based on what criteria should you buy a Cod Liver Oil?

The first thing you should do is check the label. You want to see that it contains Vitamin A and D, as well as Omega 3s. It’s also important to make sure there are no artificial preservatives or colors in your Cod Liver Oil; these can be harmful for children (and adults). If you have any questions about what a good brand of fish oil looks like, ask us. We love talking about this stuff.

The main thing to look out for is the quality of the ingredients. You should always go for Cod Liver Oil that contains only natural, high-quality ingredients and no additives or artificial flavors. It’s also important to check if it has been filtered properly and doesn’t contain any heavy metals like mercury which can be harmful when consumed in large amounts over a long period of time.

What are the advantages and disadvantages of a Cod Liver Oil?


Cod Liver Oil is the most natural and beneficial supplement you can take. It contains vitamins A, D3 and E as well as Omega 3 fatty acids EPA & DHA which are essential for good health.


The disadvantages of a Cod Liver Oil are that it is not as easily absorbed by the body and may cause some gastrointestinal upset. However, this can be avoided if you take your cod liver oil with food or at least an hour before eating. If you do experience any stomach discomfort after taking your cod liver oil, try to find one which has been enteric-coated (this means that the capsule has been coated in such a way so as to protect its contents from being destroyed by gastric juices). Also make sure that there are no additives present in the capsules themselves; these will also hinder absorption into your system.
