Omega-3s lower heart rate

New evidence suggests how fast the heart beats while at rest is a key factor in circulatory and all other causes of death.

In this review of 51 placebo-controlled omega-3 studies covering 3,000 participants, compared to placebo, those who took an omega-3 supplement had a small—but significant—average reduction in heart rate of 2.23 beats per minute.

Individually, there was no separate benefit for EPA, but DHA provided a significant benefit: an average of 2.47 fewer resting heartbeats per minute.

Doctors said this is important because most participants had normal resting heart rates, and calculate that 3.2 fewer beats-per-minute would lower chances for a sudden fatal heart event by 7.5 percent.
