Fish Oil

Is A Fish oil overdose dangerous?

As with anything in life, too much can possibly be harmful and of course fish oil is no different. However, on saying that, if you stick to the recommendations on the bottle then it will be very difficult to overdose on fish oil. Even if you do happen to accidentally take too much fish oil then the possibility of suffering severe long term effects are unlikely although if you do overdose it’s important to seek medical attention just to be on the safe side.

So what can you expect if you overdose on fish oil? The symptoms of a fish oil overdose are likely to be similar to the side effects that can be experienced with fish oil only much worse.

What are the side effects associated with Fish Oil?

It has to be said that the risk of severe side effects from taking fish oil is quite rare. The most commonly reported side effect from fish oil are fishy burps, a fishy aftertaste in the mouth and an upset stomach in the form of stomach cramps and possibly accompanied by flatulence and diarrhoea. You can help prevent this by keeping your fish oil in the fridge and only taking it along with meals.

More serious side effects can include easy bruising and an increased risk of bleeding and possibly the more serious internal bleeding which can be difficult to identify. However, there is also a risk from ingesting too much Vitamin A but only if you are taking Cod Liver Oil as Cod Liver Oil contains significant amounts of Vitamin A which can cause Vitamin A toxicity. This is particularly important for pregnant women as too much Vitamin A is believed to be harmful to the unborn baby and may result in birth defects.

If you are worried about vitamin A toxicity then it may be best to avoid Cod Liver Oil and take other fish oils which do not contain vitamin A as it is quite easy to exceed the recommended dietary allowance of Vitamin A, particularly if you are taking the fish oil over extended periods of time as Vitamin A can accumulate in the body.

Treating an overdose

If you suspect that you have overdosed on fish oil and/or are experiencing severe side effects then seek medical attention as soon as possible so that you can receive the appropriate treatment. Treatment will generally consist of alleviating or stopping the symptoms that have arisen as a result of the overdose.

Fish liver oil and Fish Oil, what’s the difference?

Fish Oil as the name suggests is oil that has been extracted from fish, particularly the oily fish such as Salmon, Tuna, Swordfish, Sardines, Herring, and Anchovies etc. These fish contain certain Omega 3 fatty acids such as EPA or Eicosapentaenoic acid and DHA or Docosahexaenoic acid that are so important for good health and which we are hearing so much about in the national press and other media.

Fish Liver Oil on the other hand, is Fish Oil that has been extracted from the liver of fish as opposed to the whole fish, Cod Liver Oil for example. Just like Fish Oil, Cod Liver Oil also contains the Omega 3 fatty acids EPA and DHA.

Many people believe that Fish Oil and Cod Liver Oil are much and such the same so it won’t make any difference which one they take but this isn’t correct. In addition to the Omega 3 fatty acids Cod Liver Oil also contains quite significant amounts of Vitamins A and D which can be detrimental to health if taken in too high a quantity.

Vitamin A Toxicity and Cod Liver Oil

With Vitamin A in particular, it is not going to be too difficult to exceed the recommended dietary allowance (RDA) as Vitamin A is a fat soluble vitamin so it isn’t as easy for the body to dispose of any excess in the diet and so it can accumulate in the body. Vitamin C for example is water soluble so any excess can be eliminated fairly easily.

Too much Vitamin A can lead to a serious condition known as Hypervitaminosis A, or in other words Vitamin A toxicity. Symptoms of Vitamin A toxicity can include nausea, vomiting, anorexia, blurred vision, headaches, muscle pain, weakness, confusion, and in severe cases, hair loss, fever, anaemia, drying of the mucous membranes and even bone fractures. If you are concerned about Vitamin A toxicity or if you are pregnant or nursing or intending to become pregnant then it is best to avoid Cod Liver Oil as too much Vitamin A has also been linked to birth defects.

Fish Oil doesn’t contain Vitamins A and D so vitamin toxicity isn’t a proble

Is Cod fish oil good for you?

This is a tricky one because the answer is both yes and no. Cod liver oil as the name suggests is taken from the liver of the Cod. Although the oil contains high amounts of the really important Omega 3 fatty acids such as Eicosapentaenoic acid (EPA and Docosahexaenoic acid (DHA), it also contains significant amounts of Vitamins A and D which although can be good for you in the right amounts, too much can prove toxic for some people. Furthermore, as we have done a good job of polluting our waters, cod liver oil may also contain harmful toxins such as mercury.

Benefits of Cod Liver Oil

The Omega 3 fatty acids in cod liver oil are the very Omega 3 fatty acids that we find so hard to source in our diet unless we eat significant amounts of fish. Normal Western diets are now so high in Omega 6 and so low in Omega 3 that many health professionals believe this imbalance to be the main cause of a rise in heart disease, inflammatory conditions and other so called ailments of the 21st Century.

Omega 6 is pro inflammatory whereas Omega 3 is anti inflammatory. What we need to do to rectify this imbalance is reduce our intake of Omega 6 and increase our intake of Omega 3 but of course this can be difficult if we don’t eat a lot of fish. This is where fish oil comes in and yes taking cod liver oil can help to increase your Omega 3 intake.

Vitamin A Toxicity

As Cod liver oil contains relatively high amounts of vitamin A it is quite possible to exceed the recommended dietary allowance and because Vitamin A can accumulate in the body, there is a risk of developing Hypervitaminosis A, a serious condition as a result of vitamin A toxicity. Vitamin A in high doses can also cause birth defects so it is not recommended for pregnant women or for anyone trying to conceive.


Another potential problem with Cod Liver Oil is the possibility of the oil containing undesirable and harmful toxins such as mercury and PCBs. This of course does not apply if the oil has been refined and purified to remove these toxins. However, not all fish oil producers regularly test their oils for purity so it is essential that if you do consider taking fish oil that you opt for a reputable one.
