The question behind the headline

Adults with elevated triglycerides; prescription EPA or EPA+DHA, usually 4 g/day in clinical studies.

What the finding does—and doesn’t—tell us

Prescription products and retail supplements are not interchangeable. DHA-containing formulations may raise LDL cholesterol in some patients. Clinical supervision matters.
