Supports is higher

Support is ahead, but a single strong opposing study can change this.

In plain English

Taking fish oil supplements every day might lower your chances of having a heart attack, but it won't make a big difference in preventing other serious heart problems or getting cancer if you're a healthy older adult.

What the research says

3 studies

  1. Study: Marine Omega-3 Fatty Acids and Prevention of Vascular Disease and Cancer

    Taking omega-3 fish oil pills daily lowered the chance of having a heart attack in older adults, but didn’t reduce the risk of strokes, other major heart problems, or cancer. So the claim is mostly right.

  2. Study: Marine Omega-3 Fatty Acids and Prevention of Vascular Disease and Cancer

    Taking omega-3 fish oil pills every day lowered the chance of having a heart attack in older adults, but didn’t reduce the risk of strokes, other heart problems, or cancer. So the claim is right: it helps with heart attacks but not much else.

  3. Study: Omega-3 fatty acids have little or no cardiovascular protection: An interventional study

    This study found that taking omega-3 fish oil pills daily didn’t really help prevent heart problems in adults, which matches the claim that these pills don’t significantly lower the risk of major heart events. It didn’t show any big benefit for the heart.
