Ascenta NutraSea is my Fish Oil of choice.I am not promoting Popeye's, but they always sell it for the lowest price.
Make sure to take your vitamin D as well.
I upped my dose from 1000 to 2000 IU last week and have been feeling much better.
It may be a placebo effect but that is fine with me.
Don't let the January blahs get you down.
