On a long session in the heat, water alone stops being enough. What you lose in sweat is fluid plus salts, and replacing only one of the two is why people still fade at the end of a ride or a match.
Iso Tonic is a carbohydrate-electrolyte drink powder built on three carbohydrate sources, dextrose, sucrose and isomaltulose, with calcium, magnesium as the bisglycinate, sodium, vitamin C and vitamin B6. A 30g serving in 500ml of water carries 573mg of sodium and 66.5mg of magnesium. Carbohydrate-electrolyte solutions contribute to the maintenance of endurance performance during prolonged endurance exercise and enhance the absorption of water during physical exercise.
Each 600G tub makes 20 servings of 500ml. This is a during-training drink and it carries its carbohydrate as sugars by design, so it is not a low-sugar product.
