Carbohydrate density has always come with a cost. Push more sugar into a single bottle and your stomach pays for it, usually right when you need it most. Maurten engineered its way around that trade-off with Hydrogel Technology, and the reworked Drink Mix 320 tightens up the details athletes kept raising. Each serving carries up to 80 grams of carbohydrate, mixes into 500ml of water, and stays gentle enough to drink through the highest-intensity hours without the gut distress that cuts fueling plans short.

The reformulation targets the two complaints that dogged the original: clumping and a heavy mouthfeel. The powder now dissolves cleanly with minimal shaking, so you spend less time fighting chunks floating in your bottle and more time drinking. The texture reads lighter too, closer to the smoother feel of the Drink Mix 160, which makes it easier to tolerate during long efforts and carbohydrate-loading sessions the day before a race.

Hydrogel Technology remains the core of what this does. Once the mix reaches the acidic environment of your stomach, it converts from liquid to gel, encapsulating the carbohydrates and carrying them through to be absorbed and used as fuel. That encapsulation is what allows 80 grams per serving to go down without the sloshing or cramping that derails high-carb fueling. Improved calcium tolerance, now up to 80 mg/L, means it mixes reliably with harder water sources when you are racing on the road or fueling somewhere unfamiliar.... Read More
