Keto Electrolytes: Replenish electrolytes & Stay hydrated on keto

Today, the keto diet is becoming more and more popular due to its simplicity and effectiveness in treating obesity and diabetes. Everyone has probably heard that maintaining electrolyte balance is an important part of the keto diet and also helps in coping with one of the most difficult periods called the keto flu. In this article, you will find the necessary information about what keto electrolytes are, their role in our body and how to replenish them.

What are Electrolytes?

Electrolytes are minerals found in the blood and various body fluids that carry a small electrical charge. The transfer of electrical charges in our body is necessary to activate and maintain different cellular and nerve functions.

Electrolytes are responsible for maintaining vital functions of the body like electrical balance in cells, muscle contractions, water balance, and pH levels. 

Here is a list of some of the electrolytes that play a vital role in your body. 

  • sodium (Na) 
  • potassium (K)
  • calcium (Ca) 
  • magnesium (Mg)
  • chloride (Cl)
  • hydrogen phosphate
  • hydrogen carbonate

Generally, people receive electrolytes from a proper and balanced diet. Eating too little or too much of certain food groups can lead to electrolyte imbalances. Electrolyte imbalances can lead to an increased risk of various diseases such as kidney, liver and cardiovascular disease. Therefore, it is essential to eat healthy foods, balance and control your macronutrient intake using nutritional labels.

The main reason our body loses electrolytes is that they are excreted in sweat and urine. In some cases, this occurs during vomiting and diarrhea.

If you want to know the exact amount of electrolytes in your body to adapt your diet, you need to get a proper blood test.

Keto flu and electrolytes

As you probably know, carbohydrates are the primary source of energy in our body. When you switch to a keto diet and cut your carbohydrate intake to less than 50g per day. As your carbohydrate intake decreases, the glycogen in your body gradually begins to deplete, and it can no longer supply the body with the necessary energy levels. Therefore, your body begins to go into a particular metabolic state called ketosis.

While in ketosis, your body starts producing an alternative energy source called ketone bodies. Ketone bodies are produced by the liver during the breakdown of fatty deposits and become the primary energy source for the body instead of glucose. As long as the body is devoid of carbohydrates, it will remain in a state of ketosis.

As for electrolytes, decreasing carbohydrate intake leads to a lower level of insulin, which is responsible for sodium balance in the kidneys. Sodium is responsible for regulating water balance in the body. When the amount of sodium decreases, the kidneys begin to secrete more water and electrolytes are washed out. This leads to an imbalance in electrolytes(sodium, potassium and magnesium), which appears as keto flu.

For this reason, you may often find recommendations for increased water and electrolyte intake to help relieve the keto flu. 

The keto flu comes with the following side effects

  • nausea
  • vomiting
  • headache
  • fatigue
  • dizziness
  • insomnia
  • constipation
  • exercise difficulties

Keto-friendly electrolytes


Sodium is an electrolyte that is responsible for maintaining the volume of extracellular fluid, conduction of nerve impulses and muscle contraction. The minimum daily dose required to maintain vital body functions is 500 mg sodium per day. The kidneys are responsible for regulating sodium levels in the body. 

An additional source of sodium for your body can be salt, also known as sodium chloride.

Diseases that caused by sodium imbalance: 

  • Cardiovascular disease
  • Chronic kidney disease (CKD) increases the risk of heart disease and high blood pressure 
  • Osteoporosis if your diet high in sodium
  • Increased risk of stomach cancer

Daily intake rate:

  • Studies have shown that for men and women aged 14 and over, as well as pregnant women, the recommended dose is 1,500 mg per day. In addition, it is stated that 2,300 mg per day is the maximum dose for reducing chronic diseases. 
  • In the case of a keto diet, you need to consume a little more sodium 3000-5000 mg as it is flushed out of the body. 
  • Daily intake information provided according to NCBI

Sodium deficiency can cause the following symptoms

  • Anorexia 
  • Headache
  • Vomiting
  • Lack of energy 
  • Muscle cramps 
  • Weakness
  • Seizures

Potassium is an electrolyte that is responsible for maintaining normal fluid levels in our cells. In addition, it helps muscles to contract, helps the heart maintain a regular rhythm, and helps the body eliminate waste products from cells. The amount of potassium in the body is regulated by the kidneys.

Daily intake rate:

  • For women aged 14-18, the intake is 2300 mg per day; for women 19+ – 2600 mg. For pregnant and lactating women, the intake rate ranges from 2500 to 2900 mg per day, depending on age.
  •  For men aged 14-18, the intake rate is 3000 mg; for men 19+ – 3400 mg
  • Daily intake information provided according to National Institutes of Health

Diseases that caused by potassium imbalance:  

  • Arrhythmia 
  • Kidney disease
  • Different genetic kidney disorders
  • Cushing’s syndrome
  • Flaccid paralysis 
  • Hyporeflexia

Potassium deficiency can cause the following symptoms

  • Elevation of blood pressure

Calcium is an electrolyte that plays a vital role in supporting various bodily functions such as blood clotting, muscle and vascular contraction, the transmission of nerve impulses, and hormonal secretion. 99% of the calcium stores in the bones and the remaining 1% supports the functions described above.

Most of the calcium comes into our bodies with food, such as milk, yogurt, and cheese.

It should also be mentioned that vitamin D is an essential element that helps the body absorb calcium. Usually, our body gets this vitamin from food or produced by the skin with sufficient exposure to sunlight.

Daily intake rate:

  • The recommended daily intake of calcium for women 19-50 years old is 1000 mg per day; 
  • For women 51+ – 1200 mg
  • For pregnant and lactating women, the recommended daily allowance is 1000 mg
  • For men 19-70 years old, the recommended daily dose is 1000 mg
  • For men 71+ years – 1200 mg

Diseases that caused by calcium imbalance: 

  • Cardiovascular disease

Why it’s important to stay hydrated on keto

Stay hydrated while on a keto diet. Because during the diet, your body loses water and electrolytes at an increased rate. As you may recall, the side effects of this process can manifest in a very severe and severe form known as the keto flu.

In order to keep the keto flu from getting overly severe, it is necessary to stay hydrated. To do this, you need to consume more water. You can achieve this in several ways. First of all, water must be with you at all times. If you don’t like drinking plain water, you can add organic flavor to it, but no sugar or carbs. Secondly, you can use a variety of bone broths to replenish your water level. Thirdly, chilled or warm lemon tea is an excellent way to maintain the body’s water balance. Finally, try to add more greens and berries to your diet because they contain a fair amount of water in their composition.

Best Keto-friendly electrolyte drinks and supplements

By following a low-carb diet, your body changes its metabolic processes to adapt to the new diet. The result of this change is an increased need for electrolytes such as sodium, potassium and magnesium. An imbalanced intake of these electrolytes can increase the risk of various diseases and cause different side effects such as losing muscle mass, experiencing headaches or weakness. Therefore, it is vital to track and plan your electrolyte intake while following the keto diet.

Nowadays, you can find many different supplements and drinks that can help you easily compensate for electrolyte deficiencies on a keto diet. Below is a list of a few keto-friendly drinks you can add to your diet.
