Agree with cleerlyseeker - nothing I've seen indicates fish oil does much of anything.

Icosapent ethyl (Vascepa and I think the new Euro approved is called Vazkepa) does show some promise, but no significant independent proof, yet), in my case, combined with atorvastatin, reduced my triglycerides to around 40, and my LDL to under 40. I have had no obvious side effects from either.
