Mechanism & formula
The electrolyte ratios: the ratio is the formula
Everyday carries sodium and potassium at roughly 1:1 by weight: 180 mg of sodium and 170 mg of potassium per serving. The proportion matters as much as the raw amounts, because it tells you what the formula is prioritizing. The ratio is the formula.
Amount alone doesn’t answer the question
Two electrolyte drinks can contain the same total sodium and still deliver a very different sodium-to-potassium balance. The ratio changes what the formula is actually doing — and there is no single right ratio for every use.
Sodium and potassium are not interchangeable. Sodium is the primary extracellular cation — it is what determines plasma osmolarity, what the SGLT1 transporter moves across the gut, and what water follows during absorption. Potassium is the primary intracellular cation — it is what muscles run on and what most American diets chronically underdeliver.
Sweat is dominantly sodium. Sodium in sweat runs about 230–2,070 mg per liter (10–90 mmol/L), and potassium far less, about 150–310 mg per liter (4–8 mmol/L). The sodium deficit from heavy sweating is acute; the potassium gap is real but slower and steadier.
What the ratio does is tell you what the formula is prioritizing. A lower ratio — closer to 1:1 — means the formula is giving potassium roughly equal standing with sodium. A higher ratio — several parts sodium to one of potassium — means the formula is treating sodium as the urgent need and potassium as a maintenance rider.
About 1:1 — sodium and potassium at near-equal weight
Everyday is designed to be sipped through the day. The job is different from acute rehydration: it is replacing the slow, steady mineral drain of an active life.
Per serving (half a scoop in 12 fl oz), the Everyday label reads sodium 180 mg and potassium 170 mg, about 1:1 by weight. Potassium sits at nearly the same weight as sodium. Most people eating a standard Western diet are already short on potassium.
Sweat is mostly sodium, so a near-1:1 drink is not a match for what a hard session takes out, and Everyday is not built to be one. It is built for the baseline. It does not close the potassium gap most diets leave open: 170 mg is a contribution, not a fix.
For scale: the FDA Daily Value used on nutrition labels is 2,300 mg for sodium and 4,700 mg for potassium. (The 2019 National Academies Adequate Intake for potassium is lower — 3,400 mg for adult men and 2,600 mg for adult women — so the label Daily Value is the more generous reference.) One serving supplies 170 mg of potassium, 4% of the Daily Value.

Its ratio is not published yet
Quick Rehydrate is coming soon. Its formula is not final, so this page states no ratio for it.
When the formula is final, its label amounts and its ratio will appear here beside Everyday’s. Until then, the only ratio on this page is the one on the Everyday label.
Everyday, by the numbers
Everyday’s label amounts are per serving (half a scoop, 12 fl oz).
| Measure | Everyday | Quick Rehydrate |
|---|---|---|
| Sodium to potassium, by weight | About 1:1 | Not yet published |
| Label, per serving (half a scoop, 12 fl oz) | Na 180 mg · K 170 mg | Not yet published |
| Availability | At launch | Coming soon |
Everyday’s ratio is on its label, and anyone can check it: 180 mg of sodium against 170 mg of potassium.
The ratio is legible
The formula is built around what the body needs across an ordinary day — not around a marketing claim about comprehensive electrolytes. The ratio is legible: about 1:1 for the baseline. If you know what you are doing and why, you can read the label and confirm it.
The total amounts matter, the per-serving doses matter, but what ratio they are held in is the design decision — the thing that makes the formula one thing and not another.
