Score breakdown
The overall score is the average of what's below, each measured against every other drink mix we've reviewed.
65
Strong
Based on 3 of 4 measures ?A dimension a product doesn't declare is left out of its average rather than counted against it -- so this score reflects fewer measures than a product with a full panel.
Carb density ?How much fuel one scoop or sachet carries. 90 g is the ceiling here, matching the top of the range cited for multi-transportable-carb intake.89
Sodium ?Sodium carried by the mix itself, on a scale topping out at 1000 mg — the upper end of what's typically lost to sweat in an hour.25
Value (cost/gram) ?Price of one gram of carbohydrate. Not physiological -- a market-based scale from $0.15/g (0) to $0.02/g (100).80

Verdict
what it does · what it costsWhat it does well
- 80 g of carbohydrate in a single 500 ml bottle, the most concentrated drink mix here alongside SiS Beta Fuel.
- 245 mg of sodium, a real contribution rather than a token amount.
- Four-ingredient label, consistent with Maurten's gel.
What it costs you
- $0.046 a gram, more than Tailwind or 4Endurance's drink for the same nutrient.
- No stated glucose:fructose ratio, the same gap as the Gel 100.
- Not sold as a single sachet at retail; you need to buy the full box to get this per-unit price.

Who this is for
the numbers, appliedThe field tells you what it is. This is who should act on it.
Worth the money if
- You already use and trust Maurten's gel and want the same approach in liquid form.
- You want a high-carb, high-sodium bottle without adding a separate electrolyte tab.
Look elsewhere if
- You want the lowest cost per gram of carbohydrate.
- You want a declared absorption ratio to plan around.
