Staying hydrated is essential for maintaining bodily functions and keeping the immune system healthy.

Maintaining hydration is also key for our brains, influencing our mood, cognition and sleep quality.

Dehydration occurs when we don’t drink enough fluid or are losing more fluid than we’re taking in, such as when we exercise.

Factors out of our control can also lead to dehydration such as climate which can make you sweat more than usual.

Nuun Hydration Review

Athletes, gym-goers and those wanting to maintain proper hydration often use rehydration products in the form of drinks, sachets, gels and powders.

Flavored sports drinks and have also been a firm favorite for athletes and fitness enthusiasts, however they can be full of sugar and carbohydrates.

This may give you an initial quick burst of energy but it probably won’t help your recovery much in the long run.

Who Uses Nuun Hydration Tablets?

These tablets are used by athletes from many different sports.

They may be particularly useful for those who take part in endurance sports and need to keep their energy and strength levels up over long periods of time.

As there are many varieties of Nuun Hydration tablets with different purposes, a variety of different demographics can use them.

For example, Nuun Vitamins is aimed at a more general audience as it contains a blend of eleven vitamins, minerals and electrolytes in a ten calorie tablet.

When we sweat, urinate, exercise or are on the go constantly we can become dehydrated and lose electrolytes.

Electrolytes are essential minerals that help to maintain the normal functioning of the body. The main electrolytes lost when sweating are sodium, potassium and magnesium.

A loss of these can lead to muscle cramps, nausea and dizziness.

For those who are training for a specific event or just ramping up their training schedule, you may find yourself feeling a little more dehydrated than usual even if you’re still drinking a lot of water.

Extra strain on the body from exercise may mean that water by itself isn’t enough to completely rehydrate you.

When To Take Nuun Hydration Tablets

You can take Nuun tablets before, during or after a workout.

Nuun recommends taking their Sport tablets 30-60 minutes before exercise to delay the onset of dehydration and keep you properly hydrated throughout the workout.

How many tablets you take depends on the individual and how quickly they lose electrolytes as well as the activity they are engaged in.

One tablet is suggested to be effective enough to rehydrate you after one hour of exercise. It is recommended that an individual takes no more than three tablets a day.

Health Benefits Of Nuun Hydration

The obvious benefit of taking these tablets is rehydration.

If you find that water isn’t hydrating enough or need more encouragement to drink it, the different flavors of Nuun tablets may help you with this.

You should get all the vitamins and minerals you need from a healthy, balanced diet and drinking plenty of water.

If you aren’t exercising or excessively sweating you should be able to naturally stay hydrated throughout the day.

As the drink is very low calorie and contains 1g of sugar, it can be a healthier option than the usual sports drinks.

This may be beneficial if you’re exercising for weight loss or have to maintain a certain weight for your sport.

Another benefit of the low sugar content in Nuun products is the accessibility factor. Some people have very sensitive digestive systems and too much sugar can aggravate this.

Many previous customers have stated that Nuun tablets don’t upset their stomachs compared to similar products on the market.
