So, you’re looking for the best hydration tablets on the market? We don’t blame you, especially since hydration tablets are essential for rehydration and maintaining optimum fluid balance. 

Here at OriGym we've created a definitive list of the best tablets on the market, including products from major brands like SIS to other popular online exclusives. 

So, let’s jump right in on how hydration tablets work! 

OR, if you have a passion for fitness and want to try something new, why not check out OriGym's Diploma in Personal Training before you carry on reading... 

How do hydration tablets work? 

It goes without saying that if you are dehydrated, you can combat this by drinking lots of water.

While this is important, the truth is that without replenishing what you have lost in electrolytes, your body will not be able to absorb as much of the water that you drink. 

Taking sports hydration tablets is one of the most effective ways to maintain hydration, as they work wonders for replacing the missing electrolytes lost through exercise (as well as replenishing your fluids). If you want to know more about hydration, see our Sports Hydration qualification

Normally hydration tablets contain a combination of salts, minerals, and glucose which will aid in the absorption of sodium (an essential element for rehydrating efficiently) through the wall of the intestine. When you correct the electrolyte balance in the blood, it will then allow the body to rehydrate by transporting water to where it’s needed most. 

Now that's covered, let's move on to the benefits of taking electrolyte tablets...

Benefits of Hydration Tablets 

You must be wondering; are hydration tablets good for you? We don't blame you for being skeptical, as they can sound pretty strange if you're not familiar with the concept. 

In a nutshell, electrolyte or hydration tablets offer a convenient method of replenishing fluids and are far more convenient for individuals or athletes who place themselves under a lot of physical stress. 

When you take sports hydration tablets you are automatically avoiding sports drinks, which often contain high levels of sugar. If the drink contains more sugar than sodium, these ingredients will not be absorbed correctly. In fact, they will actually cause a build-up in the intestines rather than replenishing hydration levels, which does more harm than good. 

Many athletes who use hydration tablets often consume them during physical activity, as this prevents them from sustaining an electrolyte imbalance (and therefore underperforming or becoming unwell). They also take care to measure their heart rate and calories burned for their own safety (and so that they can later analyse their performance), which you can do too with the help of heart rate monitors.

Now that we’ve discussed how hydration tablets work and the benefits that they bring, it's time to take a look at the products that made it onto our shortlist. Within each review, we’ll tell you when to use the tablets in your workouts for maximum hydration!
