The Best Keto Electrolytes

There are a handful of supplements that can make a world of difference when you’re following a keto diet, and electrolytes are one of them. Electrolytes are minerals in your body that carry an electrical charge. 

These charged minerals are essential for a range of bodily functions such as balancing the fluids in your body, muscle contractions, regulating blood pressure, and neurological functions — to name a few[*]. 

Many people find that when they switch to a keto diet, they lose a lot of electrolytes in the process of becoming keto-adapted. This is due to the fact that as your body learns to run on ketones, you lose quite a few of the fat-fueled energy molecules on the way. Your body starts ramping up ketone production before your metabolism is trained to use them all — so they leave through your kidneys and take electrolytes with them. 

In addition, during that first week or so on a keto diet, you’ll be burning up a lot of stored carbohydrates. When this happens, you lose water (and electrolytes) because stored carbs hold water (3 grams of water per gram of glycogen, to be exact)[*]. 

Sodium, potassium, magnesium, calcium, chloride, phosphorus, and bicarbonate are all electrolytes. However, on the keto diet, the big ones to watch out for are sodium, potassium, magnesium, and chloride. 

When your electrolyte levels become imbalanced, you may experience some unpleasant side effects, often referred to as “keto flu,” such as:

  • Headache
  • Nausea
  • Muscle cramps
  • Brain fog
  • Constipation
  • Cramping and gas
  • Fatigue 

Luckily, there is a simple solution to your electrolyte balance problem — electrolyte supplements. But not all electrolyte formulas are created equal, so we’ve put together a list of the best keto electrolytes on the market today.

Things To Consider When Purchasing Electrolytes On Keto

When looking for a keto electrolyte supplement, there are a few things to keep in mind:

Make Sure It’s Low-Carb

While electrolytes themselves won’t add to your daily carb allotment, many companies add hidden sources of carbs to either enhance flavor or as fillers. Always check the ingredient label to see if they’ve added sugars or if there are any carbs in your product. 

Ideally, your electrolyte supplement should be keto-friendly and contain zero carbs. There is no good reason for electrolytes to contain carbs, so save your carb allotment for your meals. 

Watch Out For Artificial Sweeteners

In an effort to keep carbs low and provide a pleasant flavor, many supplement companies will add low-quality artificial sweeteners like aspartame and sucralose to their products. These sweeteners are made from chemicals and shouldn’t be part of your daily regimen. 

Instead, look for companies that sweeten their products with stevia or monk fruit. 

Electrolyte Quality and Quantity 

When following a low-carb diet, the four electrolytes you want to watch out for are potassium, sodium, magnesium, and chloride. Be sure that the supplement you choose contains a balanced ratio of all four of these minerals. 

Some companies will add in extra electrolytes, or go heavy on one of two while providing minimal amounts of the rest. To stave off keto flu, you want to make sure you’re getting the correct proportion of each electrolyte. 

Preservatives or Other Chemical Compounds

Always check the ingredient label on your electrolyte supplements to ensure they haven’t snuck any low-quality chemical ingredients in there. In addition to artificial sweeteners, be on the lookout for color-enhancers and preservatives. 


Starting your day with an electrolyte drink can be a lifesaver. This is especially true when you first start the ketogenic diet and are transitioning into ketosis. To combat keto flu and replenish your stores, look for a supplement that has the top four electrolytes; potassium, sodium, magnesium, and chloride.

Sports drinks used to be the go-to for athletes, but with more sugar than most donuts, they’re really doing more harm than good. There are also plenty of mineral-rich whole foods, like leafy greens, but they won’t offer enough electrolytes for a keto dieter. Even Himalayan salt and sea salt come up short. 

This is why finding a high-quality supplement is vital. 

Electrolytes play a crucial role in cellular health, nerve function, muscle function, and more. Make electrolytes a part of your daily routine to get ahead of any potential imbalances and to keep your body fully hydrated.
