Precision Fuel & Hydration Carb & Electrolyte Drink Mix 54
A 2:1 carb blend that also declares potassium, calcium and magnesium alongside 500 mg of sodium, the broadest electrolyte profile of any drink mix here, scalable to a lower or higher concentration by how much water you add.
Score breakdown
The overall score is the average of what's below, each measured against every other drink mix we've reviewed.
54
Mixed
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.72
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.33
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.50
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).61

Verdict
what it does · what it costsWhat it does well
- 500 mg of sodium plus declared potassium (125 mg), calcium (24 mg) and magnesium (12 mg), the fullest mineral profile of any drink mix reviewed.
- Part of a scalable system: the same powder at 2 vs. 4 scoops per bottle gives you a lighter or stronger mix.
- 2:1 ratio stated directly on the label.
What it costs you
- 2:1 is the older generation of carb-ratio science, the same ceiling as PowerBar and TORQ's gels.
- $0.071 a gram, the most expensive drink mix here on a per-gram basis.
- Sold in bags only, no single-serving sachet option found.

- You want to scale concentration up or down without buying a different product.
Look elsewhere if
- You want the field-leading 1:0.8 or 1:0.77 ratio.
- You want the lowest cost per gram of carbohydrate.
