Best Potassium Supplement for Keto: Read This Review To Find Out

Keto flu can make it hard to stick to your eating plan. Keto sometimes diets lower potassium levels too far, which might make you ache, feel fatigued, or have muscle cramps.

It’s not fun.

Finding the best potassium supplement for keto lifestyles is challenging. We’re going to be taking a look at some of the products out there—and how they might be able to help you feel great as you shift into your highest health.

What Kind of Products Can Safely Restore Your Potassium Levels?

While a potassium deficiency might be the primary source of keto flu, using a potassium-only supplement could backfire. For one thing, getting too much potassium can be as dangerous as not getting enough.

Maybe more so.

Too much potassium can permanently damage your heart. There are other electrolytes to consider, too.

Sodium, magnesium, and calcium all play a part in keeping your body hydrated during keto. They help you avoid the fatigue, brain fog, and muscle cramps that can come when your electrolytes are out of balance.

This means the best potassium supplement for keto could be a supplement that’s balanced with other electrolytes, as well.

Some of the most popular electrolyte supplements for keto are sold in pill or capsule form. They range between $15 and $35 per bottle on

Some people report increased energy, better sleep, improved muscle function, and an overall sense of wellbeing with these products.

2020’s Reviews of The Best Potassium/Electrolyte Supplements for Keto Fans

To help with your decision, we’ve researched some of the top-selling potassium supplements on the market.

#5. Code Age Keto Electrolyte Capsules

Code Age keto electrolytes claim to be a high dosage supplement that requires only 1 capsule per day, taken with water. However, the instructions say that adults can safely take up to four doses a day.

One bottle contains 180 capsules, so it’s a decent buy for the price. Even at four capsules a day, one bottle would last 45 days.


  • Sodium
  • Magnesium
  • Potassium
  • Calcium

What does this supplement help with?

  • Muscle cramps
  • Mental fog
  • Fatigue
  • Poor sleep

What other people say:

  • “Wow. I can’t believe how much my energy has returned, and it has lessened my leg cramps considerably!”
  • “This product is not a high dose as it is advertised to be. The required electrolytes for keto diets are much higher than what is in this product.”
  • “I take one in the morning and once at night. My migraines are gone and I have ten times the energy.”

You can check the price here:

Things we liked:

  • Compared to similar formulas, you get a lot more capsules for about a quarter of the price.
  • Most people who use this product seem to feel better within a week.
  • Top-notch customer service

Things we didn’t like:

  • There’s only 100 mg of potassium in one capsule. Ingesting more than the recommended amount still wouldn’t boost your potassium levels very high, and it might give you diarrhea.
  • Some sources say calcium isn’t needed in an electrolyte product. We say the space taken up by calcium could be used for more potassium.
  • Poor packaging leaves messy electrolyte powder on the capsules.

How Do These Types of Products Work?

Finding the best potassium supplement for keto is about more than just pulling a bottle of supplements off the shelf. To make the best choice, you need to understand how potassium works in the body.

1. What’s a Potassium Deficiency Like?

A few uncomfortable things happen when your body doesn’t have enough potassium.

Potassium impacts the way your muscles move, including your heart. If you don’t have enough potassium, you could experience muscle cramps. (1, 2)

You might also experience heart arrhythmia, which is when your heart beats out of its normal rhythm. Finding the best potassium supplement for keto might help you avoid this scary situation.(3)

2. Why Do Potassium Deficiencies Happen?

Some people have low potassium levels because they suffer from a genetic disease such as Bartter syndrome or another chronic kidney disease.  This causes them to lose a lot of potassium through urine. (4)

potassium becomes an issue for people on ketogenic diets because keto flushes stored water out of the body.

For every gram of glycogen stored, the body also stores around three grams of water. During a keto diet, as glycogen is used up, that water is released. (5)

3. It Might Feel Like a Flood.

As the kidneys remove the extra water from the blood, they also remove sodium and potassium. This can result in dehydration and depleted electrolytes.

This is when low potassium levels become an issue, and people begin to experience keto flu.

4. Are There Natural Ways to Boost Potassium Levels?

Sure. Many wellness issues can be treated through diet, and keto flu is one of them.

Eating vegetables loaded with vitamin K can make a difference. Spinach, avocados, and mushrooms are great choices. Some meats can help, too.(6,7)

However, it might be hard to switch from a fast-food diet to a plan based on vegetables and fat. At least in the beginning, finding the best potassium supplement for keto can keep you going. At the same time, you figure out your favorite keto eating plan.

5. Why Do We Use Electrolyte Supplements To Support Keto Diets?

Around 98 percent of adults in the United States aren’t getting enough potassium from food. That problem is compounded when you start a keto diet and start flushing potassium out of your system. (8)

To be healthy, adults need 3,500-4,700 mg of potassium per day. Finding the best potassium supplement for keto could be essential for healthy weight loss as well for avoiding keto flu.

6. What’s The Best Way to Use a Potassium Supplement?

Your best bet is a mix of healthy eating and using the best potassium supplement for keto diets.

Check the milligrams per capsule for the supplements you’re considering and compare it to the foods you plan to eat during the day. Some quick math could help you figure out how much of the supplement to take to complement your diet.

Finding the best potassium supplement for keto fans means you’ll have to do some planning. On the days when you don’t eat as much spinach, consider upping the dose of your electrolyte supplement.

What Potassium Supplement is Best For Keto Diet?

Finding the best potassium supplement for keto lifestyles can be a tricky deal. The number of capsules and the amount of each electrolyte in different supplements make it difficult to compare the value side by side.

That said, we’ve found a favorite we like: the Hi Lyte electrolyte supplement best.

Here’s why:

One: while it includes sodium, it focuses more on magnesium, which can help with muscle cramps alongside potassium.

Two: Since many Americans are zinc-deficient, it’s nice to see this added as a supplement that’s seeking to balance electrolytes.

Three: It contains about 50 percent more potassium than some of the other products reviewed in this article—and this is the real game-changer. If you’re looking for the best potassium supplement for keto diets, the amount of potassium in this one makes it a top choice.
