how to test fish oil purity...is this true?

[Guest guest]

Hi, I was researching a means to test the purity of fish oil supplements.

Allegedly one should try freezing the capsules for 3 hours as a quality test.

If they freeze completely they are very low quality.......if they freeze

partially, they have impurities in them. The highest quality Omega 3s would

stay

liquid. Any opinions about this? Thanks. Lisa

Never heard this, yet there is a lot I do not know. However, I have

read if you have problems with after affects ie burping etc from tatking

fish oil supplements, to freeze them and they should pass through the

stomach into the intestines before melting reducing after affects.

The most important thing is to make sure that the fish oil is free of

PCB and Mercury. The only product I know that is free form PCB &

Mercury is Cod Liver Oil from Kirkman

A chemist friend told me that only molecularly distilled fish oil is

safe from heavy metals.

This doesn't really work for a normal freezer, the capsule will become

liquid almost immediately upon removal from freezer!! I know, because

that's where I keep the capsules. What works is taking the pills either

at night before going to bed with a glass of water or taking a few

minutes before taking a large meal! I do that with liquid Cod liver oil!

I suppose it figures really re the purity of the oil as fish themselves

don't freeze do they!

I have read that healthy (omega-3 rich) fish oil is only obtained from the

blue fish living in the coldest waters, as these fatty acids have a powerful

" antifreezing " effect, which is why these fish have become rich in it in the

first place.

 

So not all blue fish have the same amounts (or quality?) of omega3 in their

oil. For instance, tuna species living in warmer seas are supposed to be

very poor in it, or lacking it altogether (also farm fish if they have not

been fed with a source of omega-3).

 

Therefore, it seems to make sense that this freezing test would indicate how

rich that particular fish oil is in Omega-3, but you still would not know if

it's polluted with mercury, etc...

I was told to open the capsule into a shot glass and put it in the

freezer...

Carlson's cod liver oil is molecularly distilled.

What I know is that all the oil supplements should be treated like

virgin oils, cool, no light. I also know that fish oils should be

taken with food containing fat to be digested properly.

 

I recently got a pendulum and taught myself how to dowze. What I do now

is check everything I am about to swallow with the pendulum whether it

is good for my body or not, and it does work.
