Fishy tales – you don’t need fish oil supplements
Many labels on fish oil supplements make unsubstantiated health claims, according to this study. They found that 74 per cent of around 2,800 supplements made at least one claim relating to heart, brain or joint health. Extensive research shows there is no cardiovascular benefit to taking fish oil supplements and at high doses, they can increase the risk of atrial fibrillation (fluttering or pounding heart palpitations).
Lead author, Dr Ann Marie Navar, said: “As a preventive cardiologist, I tell my patients that if they are taking fish oil to try to avoid heart disease, they can stop because it’s not helping them. Their money would be better spent on something that will actually prevent a heart attack, like more fresh vegetables, blood pressure or cholesterol medication or a gym membership.”
