My pharmacist says they can't be compared since ethyl esters are added to help stabilize EPA and DHA, increasing thier respective molecular weights. If this is correct, knowing the difference will allow a mg/mg comparison, (Fish oil to Lovaza). Even with my insurance co-pay, Lovaza is expensive.
What is the difference (molecular weight) between Omega-3- acid and Omega-3 - acid ethyl esters?

An Omega-3-acid ethyl ester molecule weighs more than an Omega-3-acid
molecule, according to my pharmacist. What I need to know is: how much more weight does the ethyl-ester molecule add to the Omega-3-acid molecule? If an Omega-3-acid weighs X, then an Omega-3-acid ethyl ester weighs X+Y. What is the value of Y? Is it 0.3, 0.95, 1.7??? Without knowing the difference in WEIGHT, I am unable to make a relevant comparison. I hope this makes my original question clearer since the prescription (Lovaza) is over $100 per bottle. Fish oil, krill oil, flax seed oil, they all contain Omega-3-acid WITHOUT the ethyl ester (stabilizing) molecule and cost considerably less. I would like to get my cost down to dimes per day instead of dollars per day. If anyone knows where I might be able to access this information, I would be very grateful.
