At the baseline visits participants will receive their randomization schedule. Participants allocated to fish oil supplementation will be instructed to take four OmegaGenics® EPA-DHA 1000 capsules each containing 710 mg of EPA and 290 mg DHA daily; this will provide a total daily dose of 2840 mg EPA plus 1160 mg DHA for a total daily dose of fish oil of 4 grams. There will be dispensed a 6 week supply (70 capsules) Patients will take tablets with protein meal to enhance bioavailability. In addition, subjects will be asked to refrigerate the capsules, as the investigators have found in our prior studies that this step helps to virtually eliminate fishy taste or eructation. The investigators will use oleic acid as our placebo. The reason for the use of oleic acid is several-fold. First, oleic acid (olive oil) capsules have a similar texture, size, color, and consistency to fish oil capsules. Oleic acid has been used as a placebo in several prior studies and is well tolerated.(1-3)
