What Are The Best Potassium Supplements Brands?

Did you know potassium is an electrolyte? It is an essential mineral that the body needs.

Here is an overview of the possible benefits of taking a potassium supplement along with a few recommendations.

If you’re a regular at the gym, you’ve undoubtedly been advised at some point that you need to make sure that you consume foods with a good amount of potassium in them to help your body recover after a workout.

But is there any truth to this? 

And if it’s really that important, should you consider taking potassium supplements?

Sure, bananas have a lot but what other foods do? 

Let’s take a look at what supplementation can do for you, and a closer look at some of our favorite potassium supplements in the market.

Potassium 101

At a basic level, Potassium is an electrolyte: one of the essential minerals in your blood that helps transmit the electrical impulses running all through your body, enabling it to move, improving blood pressure. 

Some potassium-rich foods are bananas, sweet potatoes, regular potatoes, cooked spinach, and broccoli.

Your Body Needs Potassium

It may seem weird to think our body has electric signals running through it, but the body is a complex system of cells, tissue, and fluids that are run by these signals sent out by your brain and through your nervous system.

While many of these electrolytes are found outside of cells, potassium is one of the minerals inside the cells, making it an important conductor for your body’s neurotransmission process.

Here are some of the most important roles that potassium plays within the body:

Keeping Your Brain Healthy

Good Potassium levels allow more oxygen to reach your brain, thus stimulating your neural activity and increasing your cognitive abilities; in other words, it may help you process information faster, retain that information and react quicker.

But a potassium deficiency has far more dangers than simply “getting dumber.” It’s no coincidence that people who suffer strokes are often found to have a deficiency since an optimal blood flow to and from the brain reduces the chances of clotting and preventing oxygen from reaching your brain.

There are also correlations between potassium deficiency and epilepsy since the disease is tied to abnormal nerve cell activity within the brain.

Ensuring Proper Muscle Function, Reducing Muscle Cramps and Leg Cramps

Your body needs to have a certain amount of potassium to function properly because it is the ion in your cells that stimulates the neural connectivity of muscles and the brain.

It would naturally follow, then, that high potassium levels are vital to the proper growth and recovery of muscle tissue, since it’s directly responsible for your muscles’ contractions and relaxation. Muscles grow bigger because we work them to a point of stress, after which they repair themselves to handle that stress again in the future.

Also, we all know how much our muscles — and our body as a whole — need water to function and grow.

Potassium helps maintain an optimal balance of fluids in the body and ensures that different types of cells get the right amount of fluids that they need in order to function properly.

The flipside of this is that it also helps prevent muscle cramps, which are caused by low levels of fluids and electrolytes in the muscle tissue.

Processing Macronutrients

Potassium helps ensure that the protein, carbohydrates, and fats that you consume in your diet perform how they’re supposed to when you consume them.

For instance, potassium directly participates in the process of your body using the amino acids in the proteins you’ve consumed and turned it into proteins your body can use.

When you consume carbohydrates, potassium as a role in breaking down those carbs into glucose (which is immediately used by your body as a fuel source) or glycogen (which is just a fancy term for your body storing that glucose in your muscles for later use).

Potassium is also crucial in the process of your body processing fat correctly, and/or breaking it down as needed.

Other Benefits

  • Helps with high blood pressure
  • Improves kidney function
  • Help prevent kidney stones

Do You Really Need to Take A Potassium Supplement?

So, with all those great benefits, it would only make sense for you to try and consume as much potassium as you possibly can, right?

Wrong, actually.  The best thing to do if you have low potassium is talking to your doctor who can provide medical advice on the best way to increase your intake.  Their advice, diagnosis, or treatment may be supplements or increasing potassium-heavy foods.  Plus, they can tell you the proper amount of mg of potassium needed per day.

Potassium is one of seven key electrolytes needed by the body, along with sodium, chloride, magnesium, calcium, phosphate, and bicarbonate.

Each one of them services a specific and important role, especially when it comes to ensuring the balance of fluids flowing in and out of the cells in your body.

More importantly, all of these electrolytes are delicately balanced.  If there’s an imbalance in your electrolytes, it can affect your hydration, nerve impulses, muscle function, and internal pH levels.

In other words: you can have too much of a good thing when it comes to Potassium.

Because many of the foods we consume in our diet today are loaded with preservatives, we tend to consume more of those key electrolytes than we often realize.

However, potassium is not one of them, which results in a deficiency since we’re consuming much more of those other minerals, versus the amount of potassium we’re getting.  There’s a good chance you’re probably not getting enough potassium.

Best Potassium Supplement for Muscle Cramps

  • Pills become discolored if taken out of original bottle and placed in daily pill container, which leads to questions around whether it loses potency
