A new study by the Montreal Heart Institute found that high doses of fish oil supplements do not reduce atrial fibrillation, a common type of irregular heartbeat. The study also showed that fish oil supplements did not reduce inflammation or oxidative stress markers, which may explain their lack of efficacy.
Low-dose fish oil was found to reduce seizure frequency by a third in people with epilepsy who no longer responded to drug treatment. The study also showed a modest fall in blood pressure, but no significant changes in heart rate or fat levels.
