I figure, if I'm going to spend money on Omega 3,
instead of buying supplements,
I'll go out and eat sushi ... salmon, tuna ...
or open and enjoy a can of sardines.
Eggs, spinach, broccoli, kale, and olive oil are good too.
As for the effects of Omega 3,
sushi seems to help me with things like
headache relief and joint pain relief.
(Also for the joint pain, I think eating liver helps, for me anyways.)
