IONTMAX
Hydration Drink HD 1500 800 g

IONTMAX Hydration Drink HD 1500 is a hypotonic sports drink powder designed for rapid rehydration and electrolyte replacement during physical activity. It features an exceptionally high sodium content – 750 mg per serving – and is specially designed for endurance athletes with high sodium loss through sweat. It is used before, during, and after long training sessions, races, or performance in hot environments when water alone is not enough to maintain optimal hydration.

The IONTMAX HD 1500 800 g pack contains 40 servings. One serving consists of 20 g of powder mixed in 500 ml of water. If used once daily, the pack lasts for approximately 40 days. For intense endurance athletes who consume more portions during long races or training sessions, the duration will be shorter accordingly.

Mix 1 scoop or 1 sachet (20 g) in 500 ml of water. Consume the drink as needed during physical activity or when experiencing increased fluid loss through sweat. The product is primarily intended for hydration during prolonged physical exertion. It is important to maintain the ratio of 20 g per 500 ml – a larger amount of powder will increase the osmolality of the solution, and the drink will no longer be hypotonic.

IONTMAX HD 1500 is suitable for hydration before, during, and after endurance performance. During training or racing, drink it continuously at regular intervals, not all at once in a large amount. Before performance, it helps top up electrolyte stores; during activity, it maintains fluid balance; and after exertion, it supports rapid recovery and rehydration. It is particularly important during long-lasting exertion over 60 minutes or performance in hot conditions.

A hypotonic drink has a lower concentration of dissolved substances than body fluids (blood plasma). This allows water to be absorbed into the body faster than from isotonic or hypertonic drinks. IONTMAX HD 1500 has an osmolality of approximately 178 mOsm/kg and a carbohydrate content of ≈ 3%, placing it firmly in the hypotonic range. For athletes whose primary goal is rapid rehydration – rather than energy replacement – a hypotonic drink is the optimal choice.

During intense or prolonged sweating, the body loses not only water but also electrolytes – primarily sodium. Drinking water alone without replacing sodium can lead to hyponatremia (a drop in blood sodium levels), muscle cramps, and reduced performance. Furthermore, the combination of carbohydrates and electrolytes in IONTMAX HD 1500 actively supports fluid absorption through the intestinal wall, which water alone cannot achieve.

One serving (20 g / 500 ml) contains 750 mg of sodium – an exceptionally high content compared to common electrolyte drinks. Sodium is the most important electrolyte lost through sweat, responsible for maintaining fluid balance and muscle contraction. For long-distance runners or cyclists in hot weather, a high sodium intake is crucial for preventing hyponatremia and maintaining performance.

IONTMAX HD 1500 contains a complete complex of four electrolytes. Per serving (20 g), this provides: sodium 750 mg (from sodium citrate), potassium 125 mg (from potassium chloride), calcium 24 mg (from calcium lactate), and magnesium 12 mg (from magnesium carbonate). Sodium and potassium are primarily responsible for hydration, calcium and magnesium support proper muscle function, and magnesium additionally helps reduce tiredness and fatigue.

Yes, IONTMAX Hydration Drink HD 1500 is fully suitable for vegans. It contains no animal ingredients or animal-derived by-products. All raw materials used – sucrose, sodium citrate, potassium chloride, citric acid, vitamin C, natural flavour, calcium lactate, and magnesium carbonate – are vegan. The calcium lactate in this product is of plant origin, not animal.

No, IONTMAX Hydration Drink HD 1500 is gluten-free and dairy-free. The product is certified gluten-free and contains no milk proteins or lactose. According to the manufacturer's declaration, it contains no allergens. It is therefore suitable for people with coeliac disease, lactose intolerance, or milk allergies.

No, IONTMAX HD 1500 is formulated exclusively from natural ingredients. It contains no artificial flavours, artificial sweeteners (such as aspartame, acesulfame K, or sucralose), or synthetic colours. The sweetness comes from sucrose, and the taste is refined with natural flavouring and citric acid. For athletes who prefer clean products without chemical additives, this is a key feature of the drink.

One serving of IONTMAX HD 1500 (20 g / 500 ml of prepared drink) contains 60 kcal. The energy value comes exclusively from carbohydrates – specifically 15 g of sucrose per serving. The drink contains no fat or protein. The carbohydrate content of ≈ 3% (in a 500 ml solution) is deliberately low so that the drink remains hypotonic and supports rapid fluid absorption, rather than primarily providing energy.

IONTMAX HD 1500 is primarily designed for runners, cyclists, triathletes, and ultra-endurance athletes who lose large amounts of sodium through sweat during physical activity. It benefits athletes most during exertion lasting longer than 60–90 minutes, performance in high temperatures, during summer races, or in hot climates, where sodium losses are significantly higher than during regular training.

Yes, IONTMAX HD 1500 can be combined with energy gels, bars, or other supplements. When combining it with energy gels that also contain carbohydrates and electrolytes, monitor your total intake of sodium and carbohydrates to avoid unnecessary overload. We do not recommend mixing multiple powders directly into one bottle – this may change the osmolality of the solution, and the drink will cease to be hypotonic.

The main difference lies in the sodium content and the type of drink. Common isotonic drinks typically contain 200–400 mg of sodium per serving and have an osmolality of 270–330 mOsm/kg. IONTMAX HD 1500 is hypotonic (≈ 178 mOsm/kg) with 750 mg of sodium per serving. It is therefore designed for athletes with significantly higher sodium losses for whom regular isotonic drinks are insufficient. Furthermore, the hypotonic formula allows for faster water absorption into the body.
