Sodium dose ?Sodium per serving, on a scale topping out at 1000 mg — a single dose covering the top of what's typically lost to sweat in an hour.100
Value (cost/1000mg Na) ?What it costs to get 1000 mg of sodium from this product. Not physiological -- a market-based scale from $3.00 (0) to $1.00 (100).75
Potassium ?Potassium per serving, on a scale topping out at 200 mg — roughly the upper end of typical hourly sweat loss.100
Calcium ?Calcium per serving. Weaker grounding than sodium/potassium -- sweat calcium loss is minor and not really a primary target during exercise; the 100 mg ceiling is this catalog's practical high end, not a physiological one.0
Magnesium ?Magnesium per serving, on a scale topping out at 60 mg, roughly matching cited hourly sweat-loss ranges.100

Verdict
what it does · what it costsWhat it does well
- 1000 mg of sodium per stick, roughly double the next-highest product here.
- Zero carbohydrate and zero sugar, a genuinely pure electrolyte product.
- Six ingredients, no artificial sweeteners beyond stevia.
What it costs you
- No calcium at all, the only product in this set without any.
- $1.50 a 1000mg of sodium is mid-pack, not the cheapest way to that dose.
- 1000 mg in one serving may be more sodium than some athletes want in a single dose.

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're a heavy or salty sweater who wants a large sodium dose in one stick.
- You want zero carbohydrate alongside your electrolytes.
Look elsewhere if
- You want calcium included in the same product.
- You'd rather titrate sodium in smaller doses across the day.
