Actually, you can have a blood test done to check the levels of omega 3's. I believe that they are pretty pricey and I don't know if they are covered by insurance or not. I had one done by my Dr. for free as part of a study a couple years ago and was pretty deficient (I have an eating disorder too though, so that could have effected it), but I was even eating flax seed off and on. Haven't had one done since then, but have often wondered if I'm still deficient. I also think the test might have to be sent somewhere specific as it's not a common test that is done by all labs.Originally Posted by lekawa
It's too bad there isn't a way to test whether you're deficiant or not. I tend to feel that this quy had an agenda. I still have my flax seeds every day. Even if I'm not "efficiently" converting it, I feel I may be getting enough Omega 3's anyway since I have it every day, and flax seeds have many other nutrients also. I use walnuts regularly in my cooking also. Haven't checked out the microalgae yet. Is the mercury less of a risk in microalgae than it is in fish oil?
