Great HealthWorks, the Makers of Omega XL, Reports New Independent Study: Omega-3s Positively Effect Heart Rate

New Harvard study demonstrates that omega-3 fatty acids, such as found in Omega XL, are effective in reducing elevated resting heart rate associated with sudden cardiac death.

findings suggest a highly consistent and robust effect of omega-3 fatty acids on heart rate.

One of the strongest predictors independently associated with sudden cardiac death (SCD) is elevated resting heart rate. SCD is generally defined as death within one hour of the onset of symptoms, and is most frequently caused by ventricular fibrillation. Clinicians are always interested in substances that can reduce resting heart rate, without significant side effects, for the prevention of SCD. Prior human and animal studies have demonstrated that omega-3 fatty acids, such as found in Omega XL, is one of those preferred agents that can reduce heart rate, naturally, contributing few, if any side effects.

While the cardio protective effects of omega-3 fatty acids have become widely recognized, researchers from Massachusetts General Hospital and Harvard Medical School, Boston, MA, noted prior studies on a wide range of human and animal subjects, with or without cardiac disease, all respond positively to omega-3 fatty acid supplementation with reductions in resting and stress-induced heart rates. Their subsequent research demonstrated a direct effect of omega-3 fatty acids on cardiac cell membrane electrical excitability that contributes to reduced heart rate.

Their findings suggest a highly consistent and robust effect of omega-3 fatty acids on heart rate. Given the close relationship between heart rate and SCD, the direct impact of omega-3 fatty acids on the cardiac membrane to reduce heart rate may be a critical determinant of the preventive effect of omega-3 fatty acids against SCD. Thus, the researchers concluded, increasing intake of omega-3 fatty acids would likely benefit individuals at risk for SCD.

Omega XL is one of only two Omega-3 supplements sold in the world that contains the patented stabilized marine lipid extract PCSO-524™ derived only from the New Zealand green-lipped mussel, with 30 healthy fatty acids including DHA and EPA.
