Maurten 320 is not a general hydration mix—it is a dense endurance fuel. The 80 g carbohydrate payload is clear, the ingredient list is short and the format has a coherent role in long events. The premium depends on gut tolerance and convenience, not proof that hydrogel universally outperforms properly formulated alternatives.

Formula and label
One sachet supplies 80 g carbohydrate in 500 ml from maltodextrin and fructose, with alginate, pectin, bicarbonate and salt. The mix is hypertonic according to Maurten. It should be judged as fuel; users must build tolerance and account for all other carbohydrate sources.
Laboratory and certification trail
Maurten appears among Informed Sport certified brands, but this audit did not locate a clear current batch page for the exact caffeine-free Drink Mix 320. That reduces product-level verification credit without implying a failed test.
Company accountability
The core composition is unusually concise and the company distinguishes caffeinated and non-caffeinated products. Athlete use and race visibility are not evidence points.
Where this fits
A convenient way to deliver a large carbohydrate dose when long-event plans call for it. It is excessive for short sessions and should not be purchased simply because elite athletes use it.
Limits and update trigger
No gut-tolerance test, race trial or independent assay. High carbohydrate strategies require practice and individual adjustment.
Evidence register
Source rule: Manufacturer pages establish the current label and company claims. Independent directories establish only the certification, product, region and batches they actually list. Popularity, awards and affiliate economics add zero points.
