Nrgy Gel 45 65

Item: Nrgy Gel 45
Rating: 65
Author: Lourenço Faria e Maia

4Endurance / 75 g gel / 45 g carbohydrate / $1.35

A stated 1:0.8 glucose:fructose ratio -- the same blend Maurten uses -- at 45 g carbs and 460 mg sodium a gel, for 3 cents a gram of carbohydrate, about a fifth of Maurten Gel 100's 15 cents.

Score breakdown

Each dimension below is scored 0 to 100 against a fixed scale, not against the rest of the catalog, so adding a product never moves this number. The overall score is the average of the dimensions this product declares data for. How the scales are set →

65/100

Strong

Absorption rate ?How much carbohydrate an hour the glucose-to-fructose blend can move. Scored from the stated or derived ratio (1:0.8 tops out this scale); an Estimated ratio counts the same as a Stated one here.95

Carb density ?How much fuel one sachet carries. 90 g is the ceiling here, matching the top of the range cited for multi-transportable-carb intake.50

Value (cost/gram) ?Price of one gram of carbohydrate. Not physiological -- a market-based scale from 15 cents/g (0) to 2 cents/g (100).92

Gut comfort ?A proxy, not a taste or tolerance test: shorter ingredient lists score higher, from 15 ingredients (0) to 1 (100). Nobody has actually run these through anyone's gut for this score.21

Verdict

what it does · what it costs

What it does well

1:0.8 maltodextrin:fructose ratio, stated by the brand -- the same ratio Maurten Gel 100 uses, at roughly a fifth of the per-gram cost.
460 mg sodium a gel, more than double SiS Beta Fuel's 30 mg at a similar 45 g carb load.
45 g carbohydrate in a single gel, more per serving than Beta Fuel's 40 g or Precision PF 30's 30 g.

What it costs you

75 g gel weight and volume is bulky to carry and swallow relative to concentrated 40 g gels like Beta Fuel.
The combined 'Nduranz Electrolyte Mix' figure (1.09 g) isn't broken into individual potassium/calcium/magnesium amounts on the label.
Not sold through US retailers; pricing here is converted from EUR and availability will vary.

Who this is for

the numbers, applied

The field tells you what it is. This is who should act on it.

Worth the money if

You want the 1:0.8 ratio without Maurten pricing.
You want a gel that already carries meaningful sodium instead of relying on a separate source.

Look elsewhere if

You want a compact, low-volume gel.
You need guaranteed US retail availability.
