How much fish,cod,flax oil for a 64oz Green smoothie?

I am making a nice green healthy smoothie, it has wheat grass, celery, oranges, apples, carrots.

I just need to know how much oil of each do I need for a 64oz of this stuff?

Fish oil bottle says 1 teaspoon but now I am thinking since there is so much liquid. I should put 2 teaspoons….

HALP? Lol
