Ask the doctor: What is the upper limit for omega-3 fats?

Q. There's a lot of publicity about omega-3 fats being beneficial for heart, mind, joints, eyes, and so on. There are over-the-counter products of varying size. So, this is my question: is there a daily upper limit on fish oil consumption?

A. There isn't an official upper limit, but for most people, I'd be inclined to draw the line at a gram — 1,000 milligrams (mg) — of omega-3s from fish oil a day.
