Best Electrolyte Tablets for Runners 2024

If you have never taken electrolyte tablets, you may be wondering if all the buzz is true. You have probably heard a lot about them and what they can do to improve your running performance. We'll discuss electrolytes in this article, including what they are and when you might wish to utilize them.


What are Electrolyte Tablets and What They Do?

In some situations, especially when activity is continuous, intense, and/or performed in a warm climate, sweat losses can be sufficient to cause electrolyte imbalances. Electrolyte tablets can help prevent electrolyte imbalances by rehydrating your body. They are replacing the salt, potassium, and magnesium that are lost when you sweat.

Moreover, they also include bicarbonate, which helps your body absorb the electrolytes and neutralize stomach acid. 

What Happens When Electrolytes Are Low?

Mild electrolyte imbalances may not show any symptoms. Such conditions may go unnoticed until a routine blood test detects them. Once a condition worsens, symptoms typically start to show up.

Although not all electrolyte imbalances result in the same symptoms, many do.

The following are typical signs of an electrolyte disorder:
irregular heartbeat
seizures or tremors
abdominal cramps, weakness in the muscles, diarrhea, or vomiting
feeling numb and tingly

Severe electrolyte imbalances can cause serious issues such as seizures, cardiac arrest, and even coma.

a. Why We Need Electrolytes?

Your body contains minerals called electrolytes that carry an electric charge. They are present in your tissues, blood, urine, and other bodily fluids. Here are some  example of electrolyte's functions:

- ensure that the water in your body is in balance. 
- balance the acid-base (pH) ratio in your body. 
- ensure that your heart, muscles, brain, and nerves all function as they should.

b. Can Taking Electrolytes Be Harmful?

Electrolyte tablets can be dangerous if we take it too much. For instance, hypernatremia, the medical term for having too much sodium, can result in nausea, vomiting, and diarrhea. Hyperkalemia, or having too much potassium in the body, can affect how well your kidneys work and lead to cardiac arrhythmia, nausea, and irregular heartbeat.
