Fish oil, krill oil... how do they compare to loveza?

Omega-3's: An excellent article comparing sources of omega-3 fatty acids (dha & epa) is http://www.Livestrong.Com/article/457281-lovaza-fish-oil-vs-krill-oil/.

Marketing issue: Lovaza is a pharmaceutical grade omega-3 fatty acid compound, meaning precisely manufactured under stringent regulation. Fish oil products of all types vary in strength (mg), composition (epa/dha), source, and cost. Although touted for many hypothetical health benefits with variable objective evidence of benefit, their primary approved role is adjunctive control of elevated triglycerides. Only.

EPA Best Evidence: Both epa ; dha, from phytoplankton, at very high (i.e. Purified rx) doses, tend to ↓ the triglyceride concentrations in blood. Epa (without dha ; all the other non-beneficial fats in common fish oil) has a track record of also ↓ing LDL particle number, even at lower doses ; many long-term trials have shown 12-15% ↓ deaths thus i commonly recommend purified epa, vascepa, but only 1 gm (capsule)/day.
