10 Best Electrolytes and Hydration Tablets Tested


Being and staying hydrated are vital parts of living a quality life, especially as an athlete who has specific goals in mind. It’s not just fueling your body with the right foods that will make a difference in how you feel and perform, but ensuring that you have enough of the proper liquids in your body is crucial to you. So when it comes to staying hydrated, how do you make sure you are doing it properly?

However, aside from water, we can gain further help with hydration with electrolyte tablets. It may seem a bit overwhelming once you begin looking for an electrolyte tablet to enhance your health routine, but we have done the hard work for you.

The Criteria We Used For Our Evaluation

Choosing the best Electrolytes and Hydration Tablets isn’t the easiest task. That’s why we work hard to help you make your choice. Here’s the list of the factors that should be evaluated before choosing the best one.


The product you choose must make you hydrated and this must lead to increasing muscles performance. Usually, these type of products helps with muscle cramps which aren’t very rare in runner’s world. The effects should be visible fast and you should feel the boost of an energy. These products should enlarge your endurance and make it easier for you to run even in the most unfriendly conditions, especially those with high temperatures. After taking your tablet, you should feel better but remember that if you run long miles every day, one tablet from time to time may not be enough.

Ingredients and intolerance

A good option is to search for electrolytes such as potassium magnesium and etc. Many tablets are reinforced with vitamins that will let you perform better. Carbohydrates are the next thing you should consider. They’re used with electrolytes usually when you work out more than an hour and it’s rather intensive training. A lot of products may also contain artificial flavors and preservatives.

This means that some people, especially those with allergies, may have problems with skin or even breathing. Stomach upset is sometimes also a big problem for a runner. There are more and more products that are made for people who are lactose intolerant. There are also many runners that have a very sensitive stomach so it’s better to test the tablet before using it during a race or long run. GMO ingredients are usually unnecessary in a runner’s diet so search for the products without it.

Calories and artificial flavors

While doing our research we’ve discovered that many people tend to ask how many calories there per tablet. There are many different versions of electrolytes, some have more calories, the others are advertised are low calories product. We think that it shouldn’t matter very much here as while running, you burn so many calories that one or two tablets won’t make a difference. There are many tablets, also on our list, that are under 15 calories per dose so you can take them even when you’re on the diet.

There’s one thing that we really don’t like about some electrolytes/ hydration tablets- artificial flavors. These aren’t good for our body and we think that it’s a bad idea to use this kind of tablets even if you don’t like more natural tastes. We try to avoid putting products like these on our list as we really prefer nature. Many manufacturers also offer tablets with artificial colors and this is really pointless. Just think how much you care about the color of the tablet. Well, we don’t care about the color too, we care about the effectiveness.



Other Important Factors Worth Considering


Let’s be clear, you don’t want to spend a lot of money on tablets. While searching for the best option, try to think how much tablets do you need. If you usually don’t run for long distances and you don’t dehydrate yourself very often, try to purchase a smaller tube. On the other side, if you feel you’re going to take electrolytes every day, search for big box. Remember to check the number of tablets in the package as sometimes you can find very expensive products but that’s because there are a lot of tablets in it.

Check the price for a dose or for one tablet to make sure it’s worth it. Some people try to find the cheapest tablets on the market but it can be a bad idea. When you compare the same product and you see 50 discount, it’s a great deal but when you find 90 % sale, there’s a big probability that this is fake. We wouldn’t recommend saving money on tablets because it’s something that you give to your body. You can always take off shoes if they’re uncomfortable and hurt you but it’s not the same with tablets.


You must be aware that it’s not advisable to take tablets every day as you may have too many minerals in your body. This may lead to serious problems with organs like heart or kidneys. You may need only a few tablets for most challenging workouts but still, try to supply the lost nutrients with normal drinking water. You need to focus on how much do you really need hydration because you can decide what should be the size of the product.

You can buy a package with only 10 tablets but you can also search for a package with 50 tablets. It’s really your choice which one will work better for you. Most tablets have very long validity date so you can buy for days. The problem may appear if you buy the big package of tablets and they won’t work. It’s better to buy a smaller package when buying for the first time.

The different aims of usage

Remember that investing your money in electrolytes may help not only you but also the other members of your family. Many products on our list were also made for another case. If your children have a problem with vomiting, these products may be excellent to make them feel better. They are also good for elders who tend to dislike drinking water and have a fever.


Where to buy the product?

There are many different ways of purchasing the product. You can find many tablets at your nearest pharmacy or even you can find some of them in a sports store. You can also search for your favorite tablets online. The last method is the most popular but you need to be careful while buying the product. Buy only from verified sellers to make sure that the tablets are real. See the comments of the other buyers and make sure that it’s not fake.

Remember also that when you buy online, you need to pay for the delivery in most cases and sometimes the cost of delivery is higher than the cost of the tablets. You can also visit the online website for the brand which makes your favorite tablets. You can also buy tablets in the store or pharmacy and it’s safer than buying online. Going to the store may be a good option as you can always ask an assistant for help with choosing the product. Some products, however, are available only online but in most cases, you can find your best running tablets in the nearest sports store.


When you look for electrolytes, you also search for a product that will taste fine. For some people, electrolytes are similar to medicines and they think that these tablets taste awful. That’s not true. Manufacturers are aware that people pay attention to taste and they offer a full range of different tastes. You can find fruity ones like orange but there are also more extraordinary like cola. The best option is to choose the product that doesn’t have a chemical aftertaste. It’s not worth buying tablets that have artificial flavors because they’re worse on our stomach than natural ones.




Q. Are these products suitable for children?

A. No, not every product is suitable for children. If you find the product you want, find an information about giving it to children. Most of the products are suitable for children, but not every.

Q. Are tablets the only version of electrolyte supplements?

A. No, there are more options on the market. There are tablets that are very easy to use, there are powders that aren’t more complicated and there are also beverages. Whether you choose a powder, tablet, or liquid electrolyte product, it’s best to talk with a professional to figure out what a good and safe option is for you.

Q. I’m preparing for a marathon and I work really hard, do I really need these tablets?

A. We can’t tell you if you should take tablets or now. This is your decision, however, we can tell you why you may need electrolytes or hydration tablets. When you run, especially when you run long distances, your body sweats and starts to lose the water. This water has a lot of functions in our body and if you lose it, your body starts to work worse and worse. The most dangerous cases are when you faint because of dehydration. To b keep your body hydrated all the time, it may be a good idea to purchase the tablets.

Q. Should I opt for an energy drink or electrolytes?

A. We know that for some people, the energy drink is a must have even if they don’t run a lot. The truth is, most of these colorful drinks don’t have enough sodium. Maintaining a good balance of electrolytes may be really hard especially if you run a lot or you are a more professional athlete. There are many ways to provide a good source of electrolytes like tablets, you can also buy salt capsules, gels or powders. The good news is that sodium can be also found in food. If you have been running for a long time, it may be a good idea to eat something saltier after your training- what about pretzels?

Q. Is it a good idea to bring electrolytes camping?

A. Cramping is a very unpleasant feeling that happens to every runner. If you don’t provide enough sodium and potassium, cramps can happen really often and that’s bad. Potassium helps to move the fluids and nutrients in the cells so it has a very important function. If you don’t provide enough Sodium, your muscles aren’t able to regenerate very fast and that’s why you feel much pain.

Q. What are some symptoms of dehydration?

A. This is a good question as not many people recognize the symptoms of dehydration. Sometimes dehydration is mistaken for flu or other illnesses. The first symptom that you can observe immediately is dry mouth. You have a big need for water and it’s a really uncomfortable feeling. There’s little too on urine when you’re really dehydrated. It may be also a little bit darker than usual. You also tend to be very sleepy and you feel exhausted all the time.

A headache is also a common symptom that occurs while dehydration. It’s very easy to find out if you’re dehydrated when you cry. If there aren’t any tears, it means that your body needs more hydration. You shouldn’t ignore all these symptoms as dehydration can be really dangerous. You should try to prevent it at first. Try to drink a lot of water, even if you don’t like its taste. Remember that the good option to add some taste to your water is to put some fruits into it like strawberries or lemon.

Q. Only the runners have a problem with dehydration?

A. No, there are many people who are very prone to dehydration and they’re not runners. Runners are at higher risk of dehydration because they do high intensity and many of us practice in hot weather so the water is more needed. People who have problems with kidneys or bladder are also more at risk. Even when you sick and you’ve got a fever or you vomit, your level of hydration is very low.

That’s why even doctors recommend taking electrolytes when you have these symptoms. People who want to lose weight often forget to provide their body with enough water. When you are getting older and older, your brain gets older and sometimes it can’t give you the signals that you’re thirsty. Dehydration is a very serious condition as it may lead to serious health problems especially if you have problems with kidneys. You lose water every day, the problems are getting bigger when the weather gets very hot.

Electrolytes are one of those buzzwords that everyone has heard but few people really understand (if you do bear with us). What exactly is an electrolyte?  An electrolyte is salts and minerals that carry a charge and conduct electrical impulses throughout the body.  The most common electrolytes include sodium chloride, potassium, calcium, and sodium bicarbonate. Electrolytes are essential for living organisms.

Electrolytes are an indispensable ingredient in a finely tuned and fueled body. In a simplified way, they can be thought of a group of chemicals that keeps the electrical impulses in our bodies are working properly. Ignore them at your peril, and if you’re curious there are some great articles with further depth that can be found here and here.

The bottom line is that hydration is serious business, and part of that is making sure that your electrolytes stay in the right balance. Everyone’s going to have a slightly different palate for these type of things, so try a few and see which one of the best electrolytes and hydration tablets on our list work for you.
