High dose EPA safe for warfarin and aspirin users


When it comes to recommending fish oils for health purposes there is no doubt about their benefits; indeed, people seeking health advice would be hard pushed to find a practitioner with even poor knowledge of nutrition who wouldn’t recommend fish oil to address many health concerns. Yet despite their wide use and the increasing scientific and clinical support for specific high dose, pure formulations, the fear of the anticoagulation effects induced by omega-3 intake remains a concern.

Time and again, practitioners and health food staff question me as to whether our high strength ultra-pure EPA-only products can be recommended to clients on blood-thinning medication, and until recently the answer has been “not without prior medical consent”. Although the recommendation to inform the doctor prescribing anticoagulants still stands, thanks to a barrage of recent studies and review articles I can finally, hand on heart, shout from the roof tops that omega-3s, including our pure EPA products, are safe for all individuals regardless of their cardiovascular status. Interestingly, these are not new messages and good quality RCT studies proving the safety of omega-3 use have been published in abundance over the last five to ten years. This begs the question – why has this outdated advice still not been addressed and clarified for health practitioners? An expert opinion piece written by professor of medicine Dr Harris, in the American Journal of Cardiology, sums up just how safe omega-3s can be at doses between 1-4g daily.
