Wow, what a conprehensive reply! thank you so much. I have some flax seed oil - I originally bought it to push up the amount of fats in my diet but now I see it is of some other nutritional use.

I bought the evening primrose because they were on offer and I had some vague idea about them being good for you!

I'm moving back to the UK soon and I'll be in a good position to find a good EPA & DHA suppliment.

The only other oil/fat I use is olive oil which I believe is neither omega 6 nor 3?

Once again thank you.

Robert
