Description

Formulated to support both energy and hydration, this drink is enriched with sodium and magnesium, two key electrolytes lost through sweat. These minerals help you maintain fluid balance and reduce the likelihood of cramping during prolonged activity. Its isotonic formulation promotes rapid absorption, making it ideal when hydration and fuel need to be delivered quickly and effectively.

Made with natural ingredients and completely free from artificial sweeteners, flavours, and colours, Amacx Energy Drink is a clean and easily digestible option that’s gentle on the gut. It’s suitable for vegans and those avoiding lactose or gluten, making it an inclusive choice for a wide range of dietary needs. Available in refreshing Lemon, Forest Fruit, and Grape flavours, it's both functional and enjoyable to consume.

This energy drink is particularly useful for sessions lasting over two hours, when glycogen stores start to deplete. For a comprehensive fuelling strategy, combine it with other products from the Amacx Energy Line such as Drink Gel, Energy Fruit Chew, or Fast Bar, ensuring you meet your unique carbohydrate and hydration targets.

How does it work

Amacx Isotonic Energy Drink works by combining two carbohydrate sources, glucose and fructose, in a 2:1 ratio. This takes advantage of both intestinal transport systems, allowing more carbohydrates to be absorbed and used as energy compared to traditional single-carb drinks. As a result, athletes can consume up to 90g of carbohydrates per hour, helping to delay fatigue and maintain performance during long sessions.

Its isotonic nature means the drink closely matches the body’s natural fluid balance, promoting fast gastric emptying and efficient hydration. The added electrolytes sodium and magnesium support muscle function and help replace what’s lost through sweat, reducing the risk of cramp or dehydration.
