Re 3-6-9 oils. It ia always good to hear about health professionals with a wider interest. 3 6 9 s are very good in general terms just maybe not the best especially for whose metabolism might already be upset. Even with a three six nine there would be arguments for including fish oil or similar.
The KEY is balancing the omega threes and sixes. IF 3 -6 -9 is the only fat intake then dependant on the exact omega three six balance and inclusion of DHA and EPA etc the product that would cover things.
BUT many of the three six nines do not include sources of DHA and EPA which are KEY again KEY players in this. Check the label.
However as six is everywhere due to inclusion very many processed foods (vegetable oils), and the balance in our animals and many farmed fish has been pushed towards omega six by inclusion of grain in their food it is likley to be three that most people have to supplement.
Fish oil does include a range of fats for me and would come before a 3 6 9. Flax oil also has some six as well as being high three and so the inclsuion of a little flax seed or oil would ensure sixes and the basic omega three element linolenic acid n18:3.

There are arguments for GLA and they undoubtably have a place, but if omega three is the team it MAY be that GLA is substitute no 1. I dont say dont take GLa just watch the sixes it comes with and be aware it is on the cox 1 and 2 pathway so probably moderation.
I was in the 3 6 9 category about a year ago, and it took my awhile to understand those who said it may not be the optimal option given current dietary general trends. Once I twigged what they were arguing I moved from that to a small amount of olive (virgin oil) dessert spoon and about 5tps of a quality fish oil a day. I rely on nuts and food sources etc for my omega sixes.
It is complex. There are no straight forward answers. Trials have not been done.
Stored body fats may also be a factor e.g. people could build up omega sixes in body fat which would be an argument for much higher omega threes whilst your body fats balance out which could take a long time two to three years or more.
I do not regard myself as a guru but in my free time have been reading extensively round the subject and trials for many months.
Tests are available fro omega three six in the body etc see a book Smart Fats By M Scmidt
You should consult you advisor in respect of significant dietary changes.
