DRRC--I have not come across any PlusEPA blood levels. The contents of PlusEPA are oxidized...they smell like fish. Vascepa is not oxidized, due to patent capsule design and content. The oxidation of PlusEPA likely will effect the pharmaceutical potency.
PlusEPA 4 Gm / Day = $147.96 per month unknown pharmaceutical properties
Vascepa 4 Gm / Day = use the coupon or your insurance (worse case out of pocket) $200 per month
