The 25 Cent Heart Failure Solution You NEED to Know About

Are you the victim of outdated medicine?

If you’re living with heart disease, chances are the answer is yes.

I already warned you earlier this week that one of the most popular heart drugs in America can actually increase your risk of complications and death! (If you missed it, you can catch up HERE.)

Now, according to a groundbreaking study in the New England Journal of Medicine, a common mineral that’s available for pennies per dose can significantly reduce heart failure risk, dangerous cardiac arrhythmias, and death in high-risk patients.

Yet, chances are your cardiologist has never mentioned it before.

The POTCAST trial tracked 1,200 heart patients with implanted cardioverter defibrillators (ICDs) for 3.3 years.

Their mission? To determine whether a common mineral can aid in heart health.

All of the patients had low potassium levels at the start of the trial. (This was defined as 4.3 mmol per liter or lower.)

One group was given treatments designed to increase their plasma potassium to a high-normal level of 4.5 to 5.5 mmol per liter. This included potassium supplements and/or mineralocorticoid receptor antagonists, and dietary advice on how to increase their potassium levels.

The second group received standard care.

Three years later, those participants whose potassium levels reached high-normal had a significantly lower risk of being hospitalized for arrhythmias or heart failure, and a lower risk of dying from any cause at all.

This study builds on decades of research showing potassium’s crucial role in heart function.

The mineral helps maintain the electrical balance of your heart, assists with heart muscle contractions, and it regulates the heart’s rhythm.

Most people should be able to get enough potassium from their diets. It’s found in every fruit, vegetable, legume, or meat that you eat. If you’re avoiding ultra-processed foods and eating a whole-foods diet, as I always recommend, potassium levels shouldn’t be a problem.

But if you’re at high risk for heart disease, don’t guess at your levels. Have them tested, and if necessary, ask your doctor about taking supplements until you reach your goal.

Keep in mind, potassium does have a sweet spot.

Too high, and it can lead to irregular heartbeats, weakened heart muscle contractions, and heart attacks. Too low, and it can increase the risk of dangerous arrhythmias.

According to this study, an ideal level to aim for is 4.5 to 5.5 mmol per liter.

Instead of blindly doling out dangerous beta blockers, more doctors should focus on using natural heart failure prevention tools like potassium.

Treatments don’t have to be expensive—or come in a bottle—to be effective.

P.S. This hidden in plain sight heart “prescription” outperforms Big Pharma drugs.
