What the research says

The short version

Several large trials of omega-3 supplements found no reduction in heart attacks or strokes, although triglycerides fell in at least one. Benefits for dry eye were also not shown in a large trial.

Doses around 4 g a day slightly raised atrial fibrillation risk in two large trials, and high doses may prolong bleeding time.

About "most pills": NIH ODS: a typical fish oil supplement provides about 1,000 mg fish oil, containing 180 mg EPA and 120 mg DHA, though doses vary widely.
