Flax Seed Oil, Flax Oil: Difference?

[monty2589]

Is there a difference between the two? Cause all I can find in liquid form is Flax oil. I can't find any Flax Seed Oil in liquid form. They're all in gel pill form but which would be better the pill or the liquid and is this a good thing to take if you're trying to put on mass?
