Nduranz
Zero Drink 20 effervescent tablets

Nduranz Zero Drink are sugar-free, carbohydrate-free, and calorie-free effervescent electrolyte tablets designed for rapid rehydration during training and racing. Each tablet replenishes sodium, potassium, calcium, magnesium, and chlorides – minerals lost by the body through sweat during endurance activities. It is intended for runners, cyclists, triathletes, and other athletes who need to maintain electrolyte balance without consuming additional energy.

Preparing Nduranz Zero Drink is simple – drop 1 effervescent tablet into 500 ml of water and wait until it is completely dissolved. During sports activity, it is recommended to drink approximately 1 serving per hour. If you are simultaneously using nutrition with electrolytes (such as energy gels or isotonic drinks), adjust your total electrolyte intake as needed and supplement with plain water.

Nduranz Zero Drink is primarily intended to be consumed during physical activity, with a recommended frequency of approximately 1 serving (1 tablet in 500 ml of water) per hour. You can also drink it before training for pre-hydration or after training to replace lost minerals. It provides the greatest benefit during prolonged performance or in hot weather when sweating is more intense.

One Nduranz Zero Drink tablet (4 g) contains 0 kcal, 0 g of sugar, and 0 g of carbohydrates. Total carbohydrates are 0.75 g, but these consist exclusively of polyols (sorbitols), not sugars. Salt content is 0.75 g, of which sodium is 300 mg and chloride is 50 mg per dose. The product is therefore truly calorically neutral and suitable for those monitoring their energy intake.

Yes, Nduranz Zero Drink is fully suitable for both keto and low-carb diets. It contains no sugars or carbohydrates – the 0.75 g of polyols (sorbitols) per tablet has no effect on insulin levels or ketosis. During a keto diet, larger amounts of electrolytes are lost, so replenishing sodium, potassium, calcium, magnesium, and chlorides is particularly important for proper muscle and nervous system function.

Yes, Nduranz Zero Drink is designed to be combined with energy gels or carbohydrate-based drinks. During long races or intense training sessions where you use gels to provide energy, Zero Drink can provide additional electrolyte replenishment without adding extra calories. In such cases, monitor your total electrolyte intake from all sources and include plain water as needed to avoid sodium overdose.

Nduranz Zero Drink contains five key electrolytes: sodium (300 mg/tablet), chloride (50 mg/tablet), potassium, calcium, and magnesium. The body naturally loses these minerals through sweat during physical activity. Sodium and chloride maintain fluid balance, potassium and magnesium support proper muscle and nerve function, and calcium is involved in muscle contraction. Regular replenishment helps prevent cramps, fatigue, and performance decline.

Yes, regular electrolyte replenishment via Nduranz Zero Drink can help reduce the risk of muscle cramps during prolonged performance. Muscle cramps during endurance sports are often associated with dehydration and mineral loss – particularly sodium, potassium, and magnesium. Each tablet provides exactly these electrolytes, contributing to normal muscle function. It is most effective when used regularly during activity, rather than reactively after cramps have already set in.

Nduranz Zero Drink contains no declared allergens. The product is free from gluten, lactose, and other common allergens, making it suitable for most people, including allergy sufferers. The ingredients are of plant origin – electrolytes in the form of citrates and inorganic salts are vegan. The sweetener sucralose and the colouring riboflavin are also commonly accepted in vegan diets. The product is also suitable for those with lactose intolerance or coeliac disease.

One pack of Nduranz Zero Drink contains 20 effervescent tablets, with a recommended dose of 1 tablet per hour of activity (in 500 ml of water). For one-hour workouts, one pack will last for 20 sessions. For longer activities, such as a 3-hour run, you will use 3 tablets, meaning approximately 6–7 sessions per pack. The compact size of the tablets makes them convenient to carry in a training bag or jersey pocket.

The main difference lies in the absence of carbohydrates and calories. Standard isotonic drinks contain 30–60 g of carbohydrates per litre and serve as a source of both energy and electrolytes in one. Nduranz Zero Drink provides only electrolytes (sodium, potassium, calcium, magnesium, chlorides) without any energy. It is therefore ideal for shorter or less intense activities, when following a keto diet, or as a supplement to energy gels where you manage energy intake separately and want control over your electrolytes.

Nduranz Zero Drink is also suitable for shorter activities, especially if you are training in hot weather and sweating heavily. For performances under 60 minutes in normal conditions, electrolyte replenishment may not be strictly necessary, but in summer or during higher intensity loads, hydration with electrolytes is beneficial even for shorter workouts. Zero calorie content means you can use it without worrying about unnecessary energy intake.

When used as directed (1 tablet / 500 ml of water / hour of activity), side effects from Nduranz Zero Drink are unlikely. The product contains sorbitols, which can have a laxative effect in high doses, but the amount in a single tablet (0.75 g) is well below the threshold. Sucralose is an approved sweetener safe for most people. Individuals with sensitive digestion or specific health conditions should consult a doctor before regularly using electrolyte supplements.
