Waves,

I've been worried about Krill in the oceans as well.
I asked a bipolar chemist on line one time about fish oil and krill and whether we had an appropriate substitute for it, given that the oceans are being over fished. He has a sciency answer that I did not understand. He seemed to be saying that we some possibility in the future of solving this.

When I remember, I take my vit D3 and then either krill oil or fish oil and two pills of flax seed oil (the flax is cheaper than the fish or krill). I take the fish / krill oil aware that I am not taking doses high enough to improve mood. I had a dentist tell me fish oil helps gum health. My pdoc told me he took it for good brain health.
