I take a gram a day of good quality cod liver oil... very important for brain health.

Omega 3 is one of the things that is present in abundance in food that grows in the wild, plant-based or not, but when we cultivate it on reused soil with only one type of fertilizer, or in animals we raise on unnatural or unvaried food sources, it starts to disappear.

You can get fish oil with certain certification labels which show they are pure and have been tested for heavy metals. Mine has an IVO label:

Most of it comes from algae so why not go straight for the source and get some Algal Oil ? more ethical/ more sustainable and prices are more and more comparable with fish oil
