Omega 3 ALA is converted to eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Omega 6 is converted to gamma-linolenic acid (GLA) and then to arachidonic acid (AA). Several studies have shown that a lower ratio of omega-6/omega-3 fatty acids is more desirable in reducing the risk of many chronic diseases and a ratio of 4:1 showing improvements. [1]
The diagram below shows the components of fatty acids
Increasing my omega 3 to omega 6 ratios
I'm removing canola oil as I cannot find a bottle that does not contain any trans fat. I currently take fish oil for EPA and DHA. Algae is another alternative but it comes with a higher cost.
I've also added coconut oil for its medium-chain triglycerides, which are rapidly digested and acts more like a carbohydrate than a fat. I'm mainly trying it out to increase energy levels [2]. Its the only saturated fat that I'm happy to consume at larger dosages.
Common sources of GLA are evening primrose oil and borage oil. Borage oil contains 20% GLA, evening primrose oil with 9% GLA and black current oil with 15-20% GLA [3]. While I've been unable to find scientific sources, I've read positive personal stories about the use of these oils for controlling hormonal acne [4][5][6].
