I just read this article. I have been taking cod liver oil (two capsules at every meal) because it benefits my mood so much. Now I am afraid that I am a little bit toxic on the vitamin A, even though cod liver oil is a superfood for me.

I think the brand I use is Carlson. Maybe some smarter people here could explain things to me?

It strikes me that the easy way to avoid the problem is to use fish oil rather than fish liver oil.

If you desire to continue to use cod liver oil you may want to compare vitamin A levels between brands and figure out what dosage of vitamin you would be receiving between it and your diet and other supplements. If that is to high for your existing brand look for a brand that you could take that would not give you excessive levels of vitamin A.

How about asking your doctor for vitamin A and vitamin D tests at your next checkup? Then you'll know if you're deficient or toxic in either nutrient, and you can adjust your dose or change supplements if necessary.

While Dr. Mercola has some good things to say, he isn't in your bloodstream.  It may be worrying about nothing.  I brought this up to my Doctor as well and they said they weren't worried about it.  They feel that people are in need of the cod liver oil.  although I just noticed that I have been buying one called "Omega 3 Fish Oil" from Nordic Naturals, who also makes "Cod Liver Oil" with A in it.  And the former doesn't put A in it.  But when I muscle test, my body is saying it prefers the Cod Liver oil.

For what it's worth.

They don't "put" vitamin A in cod liver oil. CLO is naturally high in vitamins A and D, while "fish oil" comes from other parts of the fish; it has the same EFA content without the fat-soluble vitamins.

Aaah!  Sorry about that.  Either way I think I need it.

Remember that we're all individuals. Some of us have cod liver oil (CLO) as a black dot, some as an outright avoid, some as a neutral, some as a beneficial, and some as a diamond.

Most people in the world haven't heard of Dr D and don't have SWAMIs. Most people don't know how to muscle test for supplements.  They're just guessing what their bodies need. I speculate that the people who do poorly on CLO (getting vitamin A toxicity, for example) are individuals who shouldn't be using CLO to begin with.

IMO, if you've got CLO as a superfood, and/or you're muscle testing to see if you need it, then your chances of developing vitamin A toxicity are pretty slim.

People like me (with CLO as an avoid) are the ones who do poorly on it.

Muscle testing sounds amazing. Do you recommend a good source for me to get good at doing it for myself?

try a utube video search on how it is done

I second what wise Ruthiegirl   said, there's no guessing, get tested.  I've got subclnical Vitamin A deficiency  probably cos of a never healing mouth ulcer (Oral Lichen Planus) and maybe gut damage.  It's evidenced on me by bumps on the underside of my thighs and upper arms and they never seem to go away so I take 5000 IU daily.  I also take Vitamin D to hopefully counteract (cos I avoid the sun and have autoimmune troubles).  Probably cod liver oil would be cheaper so I should look into that though it may not be standardised - it's a superfood for me so I should!  Thanks 4 reminding me!

One way to tell if you are getting too much Vitamin A may be frequent headaches.  High doses have been noted to cause those.

Have read that modern farming or extraction methods has reduced the amount of Vitamin D found in cod liver oil.  

You would have to take A LOT of cod liver oil, especially Carlson. Carlson is an excellent brand, with A and D in the right ratios.

Perhaps not take it every meal? Seems superfluous. The Weston Price people showed that tribes had many times more the amount of animal-based vitamin A in their diets than most people currently do in Western societies.

I take it on occasion.
