Electrolyte depletion can and does happen on a keto diet. To keep yourself hydrated and feeling your best, see these keto electrolyte supplements to buy.

Electrolytes are essential minerals found in your blood, sweat, and extracellular fluid. They keep us healthy by helping maintain a wide range of physiological functions, like fluid balance, pH, heart rhythm, nerve communication, and a lot more. Examples of common electrolytes include:

  • Sodium
  • Potassium
  • Magnesium 
  • Calcium
  • Phosphorous

Normally, you’d get all of the above from food.

But under certain conditions, you can lose electrolytes at a greater rate than normal, which is when electrolyte supplements to buy come in handy. The keto flu (when you first switch into ketosis), profuse sweating, and vigorous exercising are examples of conditions under which we lose these nutrients. Some medical problems can also cause electrolyte loss. 

When you lose electrolytes, you’ll definitely feel it. Electrolyte loss can leave us swollen, tired, confused, and with a rapid heart rate 1. If severe enough, these problems may warrant a visit to the ER. Preventing this problem is easy, though, with mindful nutrition and taking supplements when necessary 2.

But don’t grab the first electrolyte supplement you come across; many contain added sugar, starches, and poor quality ingredients. Plus, they may be ineffective and a complete waste of money. Instead, look for ones designed to supplement the keto diet. Below are a couple of the best options to consider in 2021.

1. Keto Electrolytes by Kiss My Keto

This electrolyte supplement in powder supplement is sold in tasty mixed berry flavor. It contains a couple of electrolytes and essential minerals that some people may find difficult to obtain on keto,3, and it includes these moderate amounts. 

For example, you’ll get 36% of the DV for Magnesium and 18% DV for zinc from a single serving of this product. Keep in mind that because you’ll get some of your daily electrolytes from other sources, this dosage is adequate.

The product is ideal if you’re trying to prevent the keto flu and to keep you feeling great on your keto journey. At 90 servings per container, this product can definitely help. But the good news doesn’t end there: Keto Electrolytes comes with highly bioavailable versions of these minerals, like calcium citrate 4 and sodium from Himalayan pink salt. 

Other than that, it’s also sweetened with stevia and does not contain any artificial colors or unhealthy preservatives.

You’ll even get your total daily requirement for vitamin C along with natural stimulants for energy and focus: coffee berry, green tea, Rhodiola, and Siberian ginseng. All of these can give you a natural mental boost.

The vitamins in question are B complex ones, which are important for energy production 5, as well as vitamin C for an immune system boost.

Found a favorite on our list? We’d love to hear if you’ve tried any of the above options, as well as other brands of keto electrolyte supplements. Tell us why they’re working for you and what other features you love about them. 

But in case you’re still looking for ways to replenish your electrolytes, make sure to buy products that contain adequate amounts of bioavailable minerals. Otherwise, it’s always a good idea to get all your nutrients from food. Supplements are meant to fill in gaps in your diet, not to be a primary source of these essential compounds.
