I'm a little confused with the relation of vitamin D3 to omega 3 6 7 9, arent they all fish oil?

Title basically. I have a D3 pills that each have 50ug(2000IU) and take one daily. (Im 107kg/200cm, is that enough?) Then I have some other pills that are omega 3 6 7 9, specific content of one pill is: - 364mg omega 3 - 42mg omega 6 - 6mg omege 7 - 130mg omega 9 - 5 ug vitamin D My confusion is that they are both marketed as "fish oil" Can I/should I take both? Thanks!

Cod liver oil generally has a lot of Vitamin D. Generic “fish oil” is usually quite processed and doesn’t contain much nutrients outside of the Omega 3s.

Vitamin D is good and is a common thing to supplement (especially for people who don’t go out much/live in darker areas), but it can be over-consumed. Omega 3s without the Vitamin D is essentially just fat wrapped in gelatin, it can’t really be over-consumed other than just taking in too many calories (which would be hard to do with fish oil supplements).
