IONTMAX
Hydration Drink HD 1500 20 g

IONTMAX Hydration Drink HD 1500 is a hypotonic sports drink powder intended for rapid rehydration and electrolyte replenishment during physical activity. It features an exceptionally high sodium content—750 mg per serving—and is specially designed for endurance athletes with high sweat-related sodium losses. 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.

Mix 1 scoop or 1 sachet (20 g) in 500 ml of water. Consume the drink as needed during physical activity or during increased fluid loss through sweat. The product is intended primarily for hydration during prolonged physical exertion. It is important to maintain the ratio of 20 g to 500 ml; adding more powder will increase the osmolality and cause the drink to lose its hypotonic properties.

IONTMAX HD 1500 is suitable for hydration before, during, and after endurance performance. During training or races, sip it continuously at regular intervals rather than consuming a large amount at once. Before performance, it helps prime electrolyte stores; during activity, it maintains fluid balance; and after exertion, it supports rapid recovery and rehydration. It is especially important for activity lasting over 60 minutes or performance in hot environments.

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 category. For athletes whose primary goal is rapid rehydration—not energy replenishment—a hypotonic drink is the optimal choice.

During intense or long-term sweating, the body loses not only water but also electrolytes—especially sodium. Drinking water alone without replacing sodium can lead to hyponatraemia (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 standard electrolyte drinks. Sodium is the most important electrolyte lost in sweat, responsible for maintaining fluid balance and muscle contraction. For long-distance runners or cyclists in hot weather, high sodium intake is key to preventing hyponatraemia and maintaining performance.

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

Yes, IONTMAX Hydration Drink HD 1500 is fully suitable for vegans. It contains no animal-derived ingredients or by-products. All ingredients 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 free from gluten and dairy ingredients. The product is certified gluten-free and contains no milk proteins or lactose. According to the manufacturer’s declaration, it is free from all allergens, making it suitable for individuals with coeliac disease, lactose intolerance, or milk allergies.

No, IONTMAX HD 1500 is formulated entirely 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 free from chemical additives, this is one of the drink's key features.

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

IONTMAX HD 1500 is primarily intended for runners, cyclists, triathletes, and ultra-endurance athletes who lose large amounts of sodium through sweat during physical activity. Those who benefit most are athletes engaged in activity lasting over 60–90 minutes, performing in high temperatures, or competing in summer races where sweat-related sodium losses are significantly higher than during standard training.

Yes, IONTMAX HD 1500 can be combined with energy gels, bars, or other supplements. When combining with energy gels that also contain carbohydrates and electrolytes, monitor your total sodium and carbohydrate intake to avoid unnecessary overload. It is not recommended to mix other powders directly into the same bottle, as this can change the osmolality of the solution and cause the drink to lose its hypotonic properties.

The main difference lies in the sodium content and the type of solution. Regular 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 specifically designed for athletes with significantly higher sodium losses, where standard isotonic drinks are insufficient. The hypotonic formula also allows for faster water absorption into the body.
