Omega 3: No protection against heart attack or strokes, say scientists
Omega 3 cannot prevent heart attack or strokes, say scientists.
According to a large and comprehensive review of the evidence, the widely held belief that taking omega3 capsules will protect you from a heart attack, stroke, or premature death is false.
Thousands of people regularly consume omega 3 supplements for years.
The belief that it protects the heart has spread – and is promoted in the marketing of the supplements – due to the findings of early clinical trials indicating that the capsules had cardiovascular benefits.

There is no evidence that omega3 supplements are beneficial, according to a comprehensive review by the respected Cochrane collaboration of all the well-conducted trials conducted internationally to test the effect of omega-3 involving more than 112,000 people.
