Want To Lower Your Resting Heart Rate? Eat More Omega-3 Fats

Your heart rate can reveal a lot about your health—an elevated resting heart rate (RHR) is a risk factor for heart problems like hypertension, plaque buildup, heart failure, and even early death (it's actually a sneaky good predictor of longevity1).

Exercise and physical fitness is one of the most known ways to improve your heart rate, but what you eat also impacts it. And omega-3s are one of the best (if not the best) nutrients that can help lower your high heart rate. 

Omega-3s target heart rate in various ways—the most direct one, however, is by acting on the electrical excitability2 of heart tissue cells. 

Each pump of the heart is powdered by electrical impulses, and omega-3s seem to prolong the time between those signals, therefore decreasing your heart rate. 

And omega-3s appear to be especially powerful at lowering RHR for people who have an elevated heart rate to begin with. 

Now, the normal range for RHR is quite wide—ranging from 60 to up to 100 beats per minute4 (bpm). For those with high levels of physical fitness or who are endurance athletes, a normal RHR may be much lower, ranging from 35 to 60 bpm. 

Anything over 100 bpm is absolutely considered high, but even being at the upper end of normal may not be ideal for you. 

There are so many reasons to up your intake of omega-3s (most of us truly aren't getting enough)—not only do they help lower a high heart rate, but they also support brain health, vision, mood, and immunity. 

If you do want to focus on heart rate, though, eating five or more servings of fatty fish every week is a good place to start. Choose from fish like salmon, anchovies, sardines, and tuna. And if five servings seems like a lot, then start with two and work your way up. 

Fish oil supplements can also be an easy way to significantly increase your omega-3 intake. To reap the most benefits, choose one that provides at least 1,000 milligrams (if not 1,500 milligrams) of combined EPA and DHA daily.
