Frequently Asked Questions
When to use, how much to take & answers to the most common questions.
Firstly, water is the best hydration fluid to consume on a daily basis, as part of a healthy, well-balanced diet. However, if you experience dehydration there are many rehydration drinks available. Oral rehydration solutions (such as Hydralyte) are clinically formulated to contain the correct balance of fluid and electrolytes. This allows for faster and more effective absorption of fluid and electrolytes by the body, and as a result, dehydration can be corrected very quickly.
In the Hydralyte range, there are ready to drink solutions, powder packets and effervescent tablets. When these are consumed according to the directions for use on packaging, they are all equally effective to prevent and relieve dehydration.
To maximize hydration, your body needs a specific formulaic balance of salt, glucose, and water. This ideal formula can access small intestine and rush water directly into the bloodstream, allowing for WAY more hydration. This activation of your Sodium-Glucose Co-Transporter (or pump) is why you’ll feel the effects of Hydralyte quickly.
Water only absorbs so much fluid. That’s why it’s not enough.
An oral rehydration solution must also have the correct tonicity to be effective. Hydralyte is hypotonic vs. your body’s cells – it has a higher concentration of water molecules. Therefore, when the sodium-glucose pump is activated, water will flow through.
Hydralyte is an oral rehydration solution clinically formulated to contain the correct balance of fluid and electrolytes to hydrate very quickly. The loss of fluids and electrolytes through sweat, vomit, pee, diarrhea and other bodily fluids can upset the balance of fluid and electrolytes in your body, causing you to not feel your best. When you drink Hydralyte to relieve dehydration, you may also relieve the symptoms and begin to feel better faster.
Short answer is: everyone! You can use Hydralyte at the gym, the office, home, car or anywhere in between. Most of our customers use the drinks, tablets, and powders to:
Replenish the body when sick from flu, cold or food poisoning (vomiting, fever and/or diarrhea)
Recover from an intense workout or exercise
Find relief from hangovers (Yup, those morning-afters we know too well)
Prevent and relieve dehydration caused by long days outside in hot weather
Hit the ground running after traveling, either by plane or car
Hydrate quickly throughout busy days or work sessions

Small amounts of sugar are actually necessary to activate hydration (hello sodium-glucose pump!). The problem is most sports drinks and beverages like electrolyte-enhanced water have far too much or not enough sugar, which actually will not hydrate you.
Hydralyte products contain 3 or 4 grams of sugar, the minimal amount needed to help your body absorb water quickly.
The short answer: yes!
Hydralyte is an oral rehydration solution specifically designed to assist in safe, rapid rehydration, making it the ideal addition to staying well hydrated on the ketogenic diet. There are just 5g of carbohydrates in a 200ml serving of Hydralyte, making this beverage keto friendly.
The signs and symptoms of mild to moderate dehydration will occur when as little as 2% of the body weight is lost through fluid. The body requires the correct balance of fluid and electrolytes (salts and minerals) to maintain everyday functions and preserve health. Internally, the body has special mechanisms which help to keep this balance in check. However, the loss of fluid and electrolytes through urine, sweat, vomit, diarrhea and other bodily fluids can upset this balance, and in some cases, a person may experience dehydration.
Some of the signs and symptoms of dehydration include:
Increased thirst
Fatigue / Lethargy
Dizziness
Headaches
Dark or decreased urine output
Sticky or dry mouth
Loss of skin elasticity
Irritability
Try to recognize the common signs and symptoms of dehydration. If and when they occur, start using an oral rehydration solution, Hydralyte, as soon as possible.
Remember that dehydration can be of particular concern for the elderly and for young children.
If you are experiencing dehydration, you need to act fast and drink an effective rehydration solution containing electrolytes. The best options are Hydralyte’s scientifically formulated electrolyte solutions as they contain the correct balance of sugar and salt, to ensure that you rapidly restore what the body has lost. Oral rehydration solutions are formulated based on the World Health Organization guidelines for rapid and effective rehydration. It is important to start drinking these products as soon as you notice any signs of dehydration (such as dry mouth, dizziness, fatigue), and sip small amounts at regular intervals to enhance absorption (better than drinking a large bottle all at the one time. You should also monitor yourself for the signs and symptoms of more severe dehydration (such as fainting or very low blood pressure) – if these happen you should seek medical advice as soon as possible.
When you are planning to exercise, you should ensure that you start in a well hydrated state. To ensure you are well hydrated, aim to drink 8 glasses of water a day. Then, during exercise your fluid intake should match your fluid outlay. A good tip is to take 2 to 3 sips of Hydralyte’s electrolyte solution while performing sustained moderate to vigorous physical activity – this will help to prevent potential dehydration.
To rapidly rehydrate the body, you need to consume a hydration beverage that contains the correct balance of glucose and electrolytes for fast and effective absorption. The World Health Organization suggests an oral rehydration solution (such as Hydralyte), which provides fast and effective restoration of both fluid and electrolytes. In situations where you are fluid and electrolyte depleted (such as in cases of stomach flu, heavy sweating or other illnesses) an oral rehydration solution may provide fast and effective rehydration.

This is not a very fun topic, we know, but it is incredibly important. Diarrhea is a common cause of moderate dehydration. Dehydration does not itself cause diarrhea.
