I believe cod liver oil is
promoted by the food and
fishing industry to reprocess its waste products and make a little extra cash.
I am with Nick in avoiding the horrible stuff. I was given it once as a
child and can still taste it. There of course are other potential toxins too
(see wikipaedia for a start.)

Subject: Re: Vit D supplements
Much as I defer to the wisdom of our grannies, it is a mistake to give
cod liver oil except to subjects who are low in vitamin A.
Co-existing with a generalised vitamin D deficiency, we appear to
suffering from a generalised vitamin A excess. It is quite rare to see low
serum vitamin A levels (in the adult population I deal with) but quite common
to see high, and even dangerously high, levels of vitamin A. I presume this
situation has developed since WWII.
Vitamin A seems to be added to many manufactured foods and is present
in most multi-vitamin supplements at rather high levels.
The problem is exacerbated by the fact that retinol, which is an
alcohol, is displaced from its hepatic storage sites by ethanol. So
subjects who consume regular amounts of ethanol are also at risk from
potential damage to the liver caused by de-localised retinol.
So please, don't recomend people to take cod liver oil as a source of
vitamin D - unless you really know what you are doing.

For those of you who
might remember "cod liver oil and orange juice" was given to
pregnant women and children during and after World War II, and I note that
some GPs have been recommending it again |
