A meta-analysis included seven studies recently concluded “marine omega-3 supplementation was associated with an increased risk of atrial fibrillation”
An article entitled: ‘Effect of Long-Term Marine Omega-3 Fatty Acids Supplementation on the Risk of Atrial Fibrillation in Randomized Controlled Trials of Cardiovascular Outcomes: A Systematic Review and Meta-Analysis,’ co-authored by JoAnn Manson, principal investigator of the VITAL Trial — has been published.
The authors concluded “In RCTs examining cardiovascular outcomes, marine omega-3 supplementation was associated with an increased risk of atrial fibrillation (AF). The risk appeared to be greater in trials testing >1g/d.”
The meta-analysis included seven studies, five of which were included in the meta-analysis reported on in a 30 April 2021 news alert, which also reported an increased risk of AF with omega-3 supplementation.
The GOED staff is returning from Vitafoods Europe and plans to review the publication in greater depth next week.
