Anybody uses fish oil instead of flax for their omega-3 intake? Seems better for your health:
"Effects of Dietary Flax Compared With Fish Oil
ALA, found in flax seed is the precursor of omega-3 fats, can be converted to long-chain omega-3 fats and can therefore be substituted for fish oils.
However, ALA is not equivalent in its biological effects to the long-chain omega-3 fats found in marine oils. EPA and DHA are more rapidly incorporated into plasma and membrane lipids and produce more rapid effects than does ALA.
Experimental studies suggest that intake of 3-4 grams of ALA per day is equivalent to 0.3 grams (300 mg) EPA per day.
Relatively large reserves of LA in body fat, as are found in vegans or in the diet of omnivores in Western societies, would tend to slow down the formation of long-chain omega-3 fats like EPA and DHA from ALA.
One advantage of the consumption of ALA over omega-3 fats from fish is that the problem of insufficient vitamin E intake does not exist with high intake of ALA from plant sources. "
