Take both
That I couldn't say. But it has been shown to reduce cholesterol significantly. How it gets there is ?
It sure did wonders for Barry Bonds.
I take a natural supplement (Nature's Way) Omega 3-6-9 that is in a "perfect ratio". Does it work? Who knows but I'm here posting away!
Flax seed oil high in Omega 6 which the body has a tough time converting to Omega 3 where as Fish oil (from pure sources) has a more readily 'assimilable' Omega 3..according to the advertising anyway...Flax also doesn't have DHA and EPA omega-3s, only ALA. DHA and EPA are what the body needs. ALA can be converted by the body to DHA and EPA, but not very efficiently. If you are taking fish oil, there is no need to take flax.
Does Omega 6 have any benefits on its own?
