Omega-3 fish oil supplements provide little vascular health benefit

Omega-3 fish oil supplements provide little vascular health benefit

Do you take supplements containing omega-3 fish oil in the belief they are helping to protect your heart? A new study suggests you could be wasting your money.


Researchers from Cochrane analysed trials involving more than 100,000 people and discovered little proof that omega-3 supplements prevented heart disease. In fact, they say the chance of getting any benefits from such supplements is one in 1,000.


However, despite this, the researchers still maintain that eating oily fish as part of a healthy diet is beneficial. Indeed, NHS guidelines state that people should try to eat two portions of fish each week, one of which, ideally, should be oily fish such as mackerel, salmon or fresh tuna. This is so they get enough “good” fats.


Speaking about the findings of the research, Prof Tim Chico, a cardiologist from Sheffield University, said: “There was a period where people who had suffered a heart attack were prescribed these on the NHS. This stopped some years ago.


“Such supplements come with a significant cost, so my advice to anyone buying them in the hope that they reduce the risk of heart disease, I'd advise them to spend their money on vegetables instead.”


Dr Lee Hooper, from the University of East Anglia, said: “The most trustworthy studies consistently showed little or no effect of long-chain omega-3 fats on cardiovascular health.”


Nevertheless, Dr Carrie Ruxton from the UK’s Health and Food Supplements Information Service said supplements containing omega-3 can still play an important role for people who don’t eat oily fish – especially as omega-3 also benefits the brain, eyes and immune function.
