Omega 3 ...too much of a good thing?

I find, especially with certain brands of omega 3 oils, that I experience an increase in anxiety & worry when I take too much. (tblspoon) Does anyone else experience this? I have a tendency to over do something that is "good" for me. I am constantly reminded that balance is key. Since most supplements are extreme, concentrated, it is probably prudent to take breaks...Dr. Sahelian often recommends 4 days on, with 3 days off. More so, listen to your body over what anyone tells you.

Hi Rob,

I have no problem with flax seed oil, which I can take in large quantities, but high potency omega 3 fish oil causes me to have weird, nightmarish dreams. I am sticking with flax!
