(Research in progress)
A study was conducted on heart rate regulation through the Institute of Cardiology at the University of Montreal. As noted above, this pilot study involving 45 patients at the Montreal Heart Institute showed that up to 2.4 grams of EPA/DHA had no adverse effects on heart rhythm. The subjects were consuming up to four softgels of o3mega extra strength for a period of 7 and a half months without ill effect. Dr Anil Nigam and his colleagues reported that the o3mega extra strength was safe, well-tolerated and without any major side effects, including bleeding and heart rhythm abnormalities (which have been anecdotally connected to certain fish oil supplements). A large scale, double-blind, follow-up study started in late 2008 and is expected to be finished in 2014.
