How Hydration Tablets Work & Why You Should Consider Them 

what are the best hydration tablets

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

While this should always be your first action when you're thirsty, the truth is that without replenishing what you have lost in electrolytes, your body will struggle to absorb as much of the water that you drink. 

Taking sports hydration tablets is one of the most effective ways to maintain hydration. This is because they become responsible for replacing the missing electrolytes lost through exercise (as well as replenishing your fluids).  

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. 

You must be wondering; are hydration tablets good for you and why you should even consider taking them - so allow us to explain.

best hydration tablet

Electrolyte or hydration tablets offer a method of replenishing fluids, and are 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.

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.

#1 Wiggle Nutrition Hydration Tablets (UK)

how to use hydration tablets

Whether you're a moderately active person or an elite athlete, hydration tablets can help you get the most out of the water that you drink, which is essential for keeping optimum hydration. 

If you’re wondering how to use hydration tablets, all you need to do is mix 500ml of water with one hydration tablet for a low-calorie drink that will help to maintain your hydration levels either before or during your workout.

Price: £7.00 

when should you take hydration tablets

These tablets are designed to ensure nothing but peak performance, they will quickly dissolve in water and ensure that you're topped up with electrolytes without having to consume extra calories. They will also meet your sodium requirements, which are proven to help with much better hydration compared to drinking water alone. 

When you do moderate to intense exercise, you could potentially lose up to a litre of sweat depending on environmental conditions. It’s important to note sodium is probably the most important electrolyte which helps to stimulate thirst, improve taste and promote absorption and retention of water. 

Dehydration regularly occurs when fluids and electrolytes are not replaced, and can often lead to fatigue, which is not only dangerous but can lead to a loss of overall motivation. SIS GO Hydro contains a specific mixture 300mg of electrolytes, and can be used either before exercise or during your sessions. 

Another way to gain extra energy from the SiS Hydro Tablets is by selecting the additional caffeine option, which will improve alertness and overall concentration.
