fish/cod liver oil

You know, I'm not sure what the difference is between fish oil and cod liver oil.

My hairdresser recommended I start taking cod liver oil, so before I bought some, I searched about it on Google, to see if I could find any warnings about it being harmful.
I did not find anything that said it was harmful, nor did I find anything about it helping hair growth. What I DID find were websites saying Cod Liver Oil helps with arthritis and mental sharpness. Apparently, Cod Liver Oil is rich in Omega-3 fatty acids.

I don't know why they don't mention this on the label of Cod Liver Oil bottles. I guess it has something to do with FDA regulations. Omega-3 must not be on the list of things the government recognizes as worthy of belonging on their little "Supplement Facts" charts.

Some of the websites said you could take Omega-3 tablets as a substitute with the same results, if you are vegetarian. I remember also reading that you shouldn't confuse Cod Liver Oil with Fish Oil, but I'm not sure how they are different.

I've done a little research and it says that cod liver oil should be taken during cool seasons like fall-winter and fish liver oil in spring-summer. What do you guys think?

Hello Ev'reebodeee!

Actually, Purple, Cod Liver Oil tablets do contain a great deal of Vitamin A, and also D. According to my bottle, one serving (3 softgels) contain 75% of your daily intake of Vitamin A, and 100% of your Vitamin D!
Which I'm not too thrilled about, since I'm already getting more than enough of both of those. I also take Centrum, and I drink a lot of milk.

GNC sells something called Triple Cod Liver Oil, which has 3x the amount of Omega-3 in each tablet, but still the same levels of Vitamins A & D. (Instead of calling it Omega-3, they call it EPA and DHA. Not sure what the difference is.)
Anyway, I reason that since the Omega-3 is what I want, I'll just take one of these Triple Cod Liver Oil a day, instead of 3 regular Cod Liver Oil a day, and get the same amount of Omega-3 with not as much Vitas A+D.

I just need to finish this bottle of regular Cod Liver Oil tablets so I can start in on my Triple Cod!

In a related tangent:
I'm always reluctant to take Cod Liver Oil tabs together with powder-based tablets like Nourishair and Centrum. I just have these visions of the Cod Liver Oil globbing up the broken down vitamin powder and interfering with the absorbtion in my belly. But that's just my imagination painting weird pictures in my mind that are in no way related to the actual biological mechanics of digestion.
I do that a lot.

But hey, it worked for those kooky people that came up with that rediculous cellular animation that shows how Pantene magically enters the cells of your hair to repair damage and smooth the cuticle! LOL What crack were THEY smoking? Who cares? That animation sold them millions of bottles of conditioner!
