Cod Liver Oil Benefits, Side Effects and Capsules

Cod liver oil was the bane of children in Britain during the Second World War and the after war period.  They were made to swallow a large spoonful everyday to keep their minds and bodies healthy at a time when food was scarce.  They might have hated the taste of it, but it did as was promised and kept them healthy and enabled them to grow up strong.  Those children would have been amazed today at how willingly people buy and take cod liver oil, but then again, at least we can.

Taking Cod Liver Oil Benefits Us All

Cod liver oil is oil extracted from the liver of the cod fish.  The main cod liver oil benefits are that it is rich in Vitamins A and D as well as Omega 3 essential fatty acids, EPA and DHA.

During the Second World War it was given to children due to its high Vitamin D content, as this helps to prevent rickets.  The Vitamin A it contains helps the body to fight infections and is vital for healthy growth and development as well as healthy eyesight.

At the time, no-one was that aware of the values of essential fatty acids, but today we know that the two essential fatty acids found in cod liver oil, EPA and DHA are vital for the body to function properly.  Humans cannot produce essential fatty acids and so we must get them from our diet.  In the west, we do not eat enough food sources of omega 3, and this is where a supplement such as cod liver oil, comes in particularly handy.

What does Cod Liver Oil do?

Cod liver oil helps the body to boost its immune system and it provides essential vitamins that are lacking from many modern diets.  Vitamin A is found in foods such as liver, spinach, carrots, eggs and cheese.  Vitamin D is only found in eggs and oily fish such as sardines, mackerel and herring.  Most people today do not get enough of these vitamins in their diet and so taking cod liver oil can mean the difference between being healthy and not being healthy. In addition, cod liver oil benefits the body by providing it with not one but two of its essential fatty acids: EPA and DHA, both of which are essential for the body to maintain correct metabolism.

Is Cod Liver Oil Good for You?

Cod liver oil is an extremely valuable supplement for most people and for most people it provides a much needed source of valuable vitamins and essential fatty acids.

The only time you should be wary of taking cod liver oil is if you have a diet that is already rich in Vitamins A and D and the omega 3 fatty acids.  Having too much of these vitamins in the body is as harmful as having a deficiency.

The following people should also be careful when taking cod liver oil and seek advice from their doctor:

  • People who are allergic to fish or nuts
  • People with diabetes
  • People with hypotension (low blood pressure)
  • People with a bleeding disorder of any kind
  • People taking NSAIDs
  • People on blood thinning tablets
  • People on Warfarin
  • Pregnant women
  • Young children (each child’s metabolism varies so you must check with your GP to discover whether cod liver oil is appropriate for your child and what dosage you can give.)

It improves the health and functioning of the cardiovascular system, the nervous system, the digestive system and the immune system.  It strengthens bones and improves the condition of your skin, hair and nails.  Plus it helps to improve brain function.
