Best Salt Tablets for Runners: When to Use Them in Running

While running, you lose thousands of milligrams of sweat, per hour, and you lose electrolytes in the process too. Therefore you need supplements to replenish the lost electrolytes while you are on the road to prevent the risks of low sodium levels.

Salt Tablets for Runners

Sadly, water doesn't contain electrolytes, and can't act as a supplement.

Hence, you will need a good salt supplement and salt tablets are usually the go to for runners.

In this article, I will be explaining:

  • why you should use salt tablets, 
  • their benefits over other electrolyte providers, 
  • review some of the best salt tablets for runners on the market which you can use while you are running and training! 

What Do Salt Tablets for runners Do?

If you have ever wondered why your sweat is salty, that's because you're losing salts when you engage in intense activities like running, and these salts are considered to be your body's electrolytes.

Your body's electrolytes control the movement of fluid in your cells, and also muscle and nerve function.

Salt Tablets for Runners What Do They Do

Electrolytes are made up of:

  • sodium - the main component
  • potassium, 
  • calcium, 
  • zinc, 
  • magnesium, and 
  • chloride. 

Why is salt so important for your body as a runner?

Sodium helps to maintain your body's blood pressure, but since your body's sodium concentration is mostly lost while you are sweating on the road, you are at a high risk of suffering low blood pressure.

And that is why you need to take salt tablets to supplement this loss to prevent your body from having lower sodium levels than required.

The salts in your body also help in the absorption of fluid taken and also build the blood plasma volume.

Plasma is the liquid part of blood that contains salt/mineral, water, and protein. It is also an extracellular fluid.

The blood plasma volume gives you a high level of body fluid which helps in regulating the thermal stability of your body and also heat dissipation.

Failure to take salt tablets before or after prolonged exercise or carrying out a physical activity like running will lead to a reduction in the level of blood plasma, which will lead to an imbalance of electrolytes in the body.

This can also cause effects such as: 

  • nausea, 
  • loss of energy, 
  • confusion, and 
  • headaches 
  • drowsiness
  • and in extreme cases seizures, coma, and even death

The best way to keep this in check as a long distance runner is by taking salt pills as supplements.

This can also cause effects like nausea, loss of energy, confusion, and headaches and lead to extreme cases like drowsiness, seizures, coma, and even death.

And one of the best ways to keep this in check is by taking salt pills, as supplements.

Why Salt Tablets for runners?

One of the best things that you can do to perform well in a race, is to stay hydrated at all times.

And if you are one of the long-distance runners who participate in marathons and other long-distance races where you lose a lot of sweat and electrolytes, water alone can't provide you with the level of hydration that you need.

Salt Tablets for Runners Why Should You Take

This is because water can't replenish the electrolytes that you lose when you sweat in the course of the race.  

Therefore, you will have to get something else that can replace the lost electrolytes, and that is where salt tablets come in.

When you are losing salts through sweat and taking just water without any salt replacement source while you are running a long-distance race, it will disrupt your body’s fluid balance and cause electrolyte imbalances which will lead to the water you are drinking diluting the remaining electrolytes in your body.

And this will cause fatigue and muscle weakness faster than usual and hence slow you down significantly.  

However it can also cause a potentially life-threatening condition known as hyponatremia  which occurs when the concentration of sodium in your blood is abnormally low. (Mayo Clinic)

So, this is why you need salt tablets when you are going for a long run.

To most people the best solution for them in this case is to get the best electrolyte drink from a store and use it as a electrolyte-replacement source, which is also good, but, as you run for a long while, you tend to finish these drinks before you get to the finish line.

So, you will need another alternative that can keep you hydrated on the road, and salt tablets are a reliable, easy and safe option for you to carry along and use at certain points during a race or run.

Also, if you are one of the runners who do not like using typical sports drinks to gain electrolytes, using salt tablets is a good alternative.

Another major benefit that salt tablets have over sports drinks and other sources that can give you a sufficient amount of electrolytes, is that they are easier to carry around.

They offer maximum convenience and are excellent electrolyte supplements that aid electrolyte balance.

And this could be a factor you should consider if you are a marathon runner, and run for long periods of time.

With salt tablets, you just need to carry one full water bottle along, or two at most.

So, below is the list of salt tablets for runners that I have taken the time to review that can help you gain electrolytes whenever you go on a long-distance run or if you are to run for a long time at a high altitude.

Hopefully this will help you save time in finding the right salt supplements that fit your personal preference!

Factors To Consider While Getting A Salt Tablet

Salt Tablets for Runners Factors to Consider

Here are some key factors you should consider before settling for a salt tablet:

Sodium Content

Sodium is the main content of salt tablets.

Its relevance to your overall health cannot be overemphasized. The most acceptable content of sodium in a salt tablet should not surpass 600-1200mg.

Salt Tablets for Runners Sodium Content


A regular salt tablet contains sodium and chlorine as its basic ingredients. Some products contain or use Pink Himalayan salt which has 84 more minerals that are useful to the body compared to regular salt.

These products might come with few carb components, which can make them unsuitable for runners who are trying to stay away from sugar.

However, there are keto products that contain no carbs and are thereby sugar-free.

Tablet Size And Shape  

You should also consider the tablet size and shape especially if you have difficulty swallowing down a particular shape or size of a drug.

Salt Tablets for Runners FAQ

What Is The Downside Of Salt Tablets?

Taking more salt tablets than required can be harmful to your body.

Although it helps to maintain your body's blood pressure, too much sodium in your body puts you at a higher risk of suffering high blood pressure, which can further lead to stroke, heart attack, diabetes, kidney damage, and blood clots.

Your daily sodium intake is supposed to be about 2,300 milligrams, so if you take more than that, it will do more harm than good to your body.

I would advise that you talk to your doctor or a physician for a proper prescription of the dosage you should take, to prevent the intake of too much salt than required for your body.

Also, if you are pregnant, breastfeeding, or on any other medication, endeavor to enquire from your doctor first before taking any salt tablet.

When Do You Need Salt Tablets for runners?

You need salt tablets when you are going on a long distance run. This is because when you run for long, you lose more sweat, and hence more sodium, so you will need

However, if you are going for a short run, you don't sweat as much as you do when you go for longer runs, so taking just sports drinks or depending on the length, even just water can be enough to replenish your body with the enough electrolytes to keep you going and help you finish strong.

Salt Tablets for Runners When Do You Need

Do Salt Tablets Take The Place Of Water?

No, they do not. Although salt tablets provide your body with electrolytes and water doesn't, you still need to carry water along with you as well.

When you take a certain amount of salt tablets, you become more thirsty and you will need to take much water to quench it and prevent discomfort while you run.

You can get a hydration belt to help you carry both your water bottles and salt tablets with ease as you run.

Can I Take Salty Snacks Or Table Salt Instead Of Salt Tablets?

You can but many times, salty snacks alone don't contain enough salt for your needs.

Salt pills come packed with a dose of sodium that is suitable for the distance runner's needs, and provides you with enough salt.

Also, table salt contains only sodium which can’t provide your body with the right electrolyte balance that electrolyte pills like salt tablets which have diverse minerals have to provide your body.
