The study, by researchers at Dundee University in Scotland showed that taking 10g of cod liver oil a day can reduce the need for non-steroidal anti-inflammatory drugs (NSAIDs) by 30%. Many patients with RA take NSAIDs such as ibuprofen. However, high doses have been linked to adverse side-effects such as increased risk of heart attacks, strokes and stomach bleeding.
Researchers looked at 97 patients with RA who took NSAIDs for their condition. Some were given 10g of cod liver oil daily and others were given a dummy pill. After 12 weeks their NSAIDs were gradually reduced.
