What Is Potassium?

Potassium is both a mineral and an electrolyte. Since the body cannot produce this chemical compound itself—it has to be consumed using external means. This being, through the food you consume—or by taking the best potassium supplements for keto.

This mineral is essential for life—being responsible for ensuring fluid levels are kept at optimum levels, nerve signaling, and contracting the muscles.

If you want more detail—here’s an excellent video on the importance of potassium.

Why Is Potassium Supplementation Important for Keto?

Potassium deficiency can become an issue for those following the keto diet for two main reasons.

Firstly, foods which are high in potassium are often carbohydrate-rich too—such as sugary fruits and potatoes. As these staples need to be avoided on keto—this can lead to insufficient potassium intake.

Secondly, one of the most common side effects of ketosis—increased urination—depletes stores of this mineral. Studies have indicated that undertaking a low-carb diet results in increased water loss.

But, during urination, you’re not only expelling fluid from the body but also essential electrolytes too—including potassium.

These two factors combined can lead to health issues—which can be avoided by taking the best potassium supplements for keto.

The Downsides of Too Little Potassium

Specifically for the keto diet—a lack of potassium, combined with the body adapting to using fat as fuel instead of carbs, can lead to the symptoms of “keto flu”. While usually a short-lived experience at the beginning of the diet—it can be quite unpleasant.

Too little of this important mineral can lead to:

Using the best potassium supplements for keto can help to ensure your health remains in good shape.

Potassium Rich Foods on Keto

As mentioned, many of the potassium-rich foods such as fruits, potatoes, and beans are high in carbs—making the intake of this mineral a challenge for the dedicated keto-dieter.

However, there are some fairly good potassium providers that you can eat while following keto, including:

  • Avocados—a real powerhouse packing in 690 mg per fruit.
  • Mushrooms—just 3.5 ounces provides 318 mg of potassium with a healthy bonus of three grams of protein.
  • Brussels sprouts—low in calories and carbs, one cup of this tasty vegetable gives you 389 mg of potassium.
  • Pumpkin seeds—handy snacks for the keto practitioner which are high in omega-3 fatty acids and provide 220 mg of potassium per one-ounce serving.
  • Salmon—not just a great heart-booster, this fish contains 638 mg of potassium per five ounces.

However, trying to hit your daily potassium intake every day with these foods may be tough—and monotonous. Instead, the best potassium supplements for Keto can take the strain.

What to Look for in the Best Potassium Supplements for Keto

Here are a couple of points to think about when selecting the best potassium supplements for keto.

The Type of Potassium

Potassium supplements tend to be made in three forms—citrate, gluconate, and chloride. While there are some slight differences in the way these chemically react within the body—for keto supplementation its a minor detail.

However, it’s generally considered that the citrate version is the best tolerated and most easily absorbed.


When selecting the best potassium supplements for keto—it’s valuable to consider the pill count/pack size.

If you’re considering keto as a lifestyle choice—not just a short-term diet, it may be beneficial to purchase a product which will last a long time. This means that you won’t be reordering every month and running the risk of potassium levels falling.

Other Ingredients

Some of the best potassium supplements for keto may include compounds in addition to their potassium content. This can prove useful if you feel you’re lacking in other essential nutrients.
