Fish don’t make omega 3 oils, they ingest them from algae. So you can just cut out the middle fish and get them from algae yourself, in the form of algae oil supplements.
well the omega 3 to omega 6 ratio is the point of taking O6
How do you know how much O3 you need? So O6 is in plant-oils, how many O3 Capsules do you need to eat with your salad if you put olive Oil on it?
Fish and shellfish already have the perfect ratio, unless you cook them in plant oils.
