Cod liver oil supplements


Does anyone have any information on the benefits of cod liver oil supplements? Or experience of taking it and if it had any effect? I’m. Looking at it more from a running point of view.
Thanks in advance.


Looks to be a well informed article.


My own belief is that we should aim to get all our nutrition from food. I can see why if you don’t eat certain things you might need supplements to provide missing nutrients, but if you’re an onmivore then food should give you everything you need.
