What are the key things to look for in a quality fish oil? I am currently using one from Wal Mart called SPRING VALLEY. It has 8 different kinds of fish in it and it also says it is MEG-3. 99.99% purified.

I just get the Vitamin Shoppe fish oil caps. seem to work well, and priced decently.

Basically any fish oil will do kind of:
If its Late spring to Early Autumn (fall) you should be taking fish oil
If its between Early autumn and Late spring you need Cod liver oil the difference is in the Vitamin D which we can get from the sun in the summer but tend to lack during the cooler periods. (note if you live close to the equator you should use fish oil all year round.

Now how much should you be taking?
There are 2 things you need to look for on the back of your fish oil container EPAs (Eicosapentaenoic acid) and DHAs (Docosahexaenoic acid) Together you need to get between 1000mg-1200mg (note this is not the weight of the oil its the weight of those EPAs and DHAs combined.)
My fish oil pills have 180mg of EPA and 120mg of DHA so i take 4 pills a day 180+120=300x4=1200.
its as simple as that just spread your intake throughout the day if you can for best results

For fish oil, I messed around with different brands, from expensive to cheap. I found that they were all the same for me. I use a Wal-Mart or Costco one, and it works find for me
