Potassium for Blood Pressure Support

Bundled Up Woman with Healthy Blood Pressure Spreading Joy While Hiking in the Fall Forest

Are you worried Black Friday shopping and holiday stress might raise your blood pressure? Have you ever wondered how potassium affects your blood pressure and whether or not you are getting enough? If so, this blog post is for you!

Potassium is a mineral crucial for the healthy function of all tissues and organs in your body. Potassium levels must be maintained at an optimal balance inside and outside your cells because potassium shifts play a role in nerve function, and nerves control your muscles and organs.

So, each time you move a finger - or your heart beats, potassium moves out of and back into your cells to drive the nerve and muscle function.

Continue reading below to learn more about the effect of potassium on blood pressure and how to improve your potassium level.

What are the Symptoms of a Low Potassium Level (Hypokalemia)?

Not consuming enough potassium daily can increase the following:

  • Fatigue
  • Muscle weakness
  • Muscle cramps
  • Blood pressure
  • Bone loss
  • Salt sensitivity
  • Excretion of urinary calcium
  • Risk of developing kidney stones1

Do I Need More Potassium?

According to research, only 3% of Americans consume sufficient potassium daily.2 Potassium was identified as a shortfall nutrient of public health concern in the recent report of the 2020 Dietary Guidelines Advisory Committee.2,3

Foods High in Potassium Support a Healthy Blood Pressure Level

How Does Potassium Lower Blood Pressure?

Diets containing foods that are a good source of potassium and that are low in sodium may reduce the risk of high blood pressure and stroke” is a health claim that has been approved by the FDA based on available research.1

Unfortunately, many people in the United States and across the world consume a Western Diet, also known as the Standard American Diet (SAD), which is relatively high in sodium (salt) and low in potassium.4 The unhealthy Western diet is associated with an increased risk of developing high blood pressure (hypertension) and cardiovascular disease.5

Ultimately, it is the interplay between sodium and potassium intake and management that affects your blood pressure.5 Therefore, potassium is most supportive for those who consume too much sodium.

Potassium counteracts the blood pressure-raising impact of high sodium intake by supporting the removal of sodium by your kidneys. Research suggests that the dietary sodium-to-potassium ratio is more predictive of high blood pressure than consuming either too much sodium or not enough potassium alone.3

Good Sources of Potassium - Healthy Foods that are High in Potassium to Support Healthy Blood Pressure

How Do I Increase My Potassium Level?

Potassium is present in most foods, and fruits and vegetables offer the highest potassium levels. Good sources of potassium include:

  • Apricots
  • Lentils
  • Potatoes
  • Bananas
  • Squash
  • Kidney beans
  • Raisins
  • Prunes
  • Spinach1

To increase your potassium intake, consider adding more potassium-rich fruits and vegetables to your daily menu and supplementing with extra potassium.

Also, a low magnesium level can contribute to a low potassium level by increasing the amount of potassium excreted in your urine.1 Therefore, consider boosting your intake of both magnesium and potassium if needed.

While it is important to consume adequate potassium daily, some health conditions, such as chronic kidney disease (CKD), require a low potassium intake. Thus, it is always best to discuss dietary supplements with your doctor to ensure you are taking appropriate doses of the nutrients you need for optimal health.

Excipients, also known as additives or fillers, are like candy or cigarettes because they are devoid of nourishing value and can even be harmful. Like candy and cigarettes, they allow companies to generate income or, in the case of supplement manufacturers, to save money during the manufacturing process, but they are not healthy for us to consume...
