Flax oil questions

[frankenfurter]

OK, so I am about to go buy some flaxseed oil for the first time to add to my diet. Anything specific I should look for? Are there different "qualities" of oil, for example like there is whey concentrate and isolate? Is there an expiration date? Are there different strengths?

Thanks in advance.

Look for an oil w/ a high lignan content.

Look for cold pressed organic flax oil. Once you open it, make sure you refrigerate it and try to avoid exposing it to light as much as possible.
