UnTapped Maple-Based Energy Gel 45
A single ingredient — organic Vermont maple syrup — and nothing else, at $0.087 a gram, a genuinely short answer to the question of what's actually in a gel.
Score breakdown
The overall score is the average of what's below, each measured against every other gel we've reviewed.
45
Mixed
Based on 4 of 5 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 sachet carries. 90 g is the ceiling here, matching the top of the range cited for multi-transportable-carb intake.29
Sodium ?Sodium carried by the gel itself, on a scale topping out at 1000 mg — the upper end of what's typically lost to sweat in an hour.1
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).49
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.100

Verdict
what it does · what it costsWhat it does well
- One ingredient. The shortest label of any gel we've reviewed, by a wide margin.
- USDA organic, single-origin Vermont maple syrup.
- $0.087 a gram, close to the cheaper end of the field.
What it costs you
- No glucose-to-fructose ratio: maple syrup's sugar composition is whatever the tree and the season produced, not a controlled blend.
- 5 mg of sodium, functionally none.
- Flavor is exactly and only maple, which some find fatiguing late in a long race.

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 want the shortest possible ingredient list and don't need a stated ratio.
- You like maple flavor and want it unmixed with anything else.
Look elsewhere if
- You want a verified absorption ratio.
- You need the gel to carry meaningful sodium.
