Walk down any electrolyte aisle and the sodium numbers are all over the place. One stick prints 88mg. Another prints 330mg. A third prints 1,000mg. They all call themselves hydration, so what is the right number?
The honest answer: it depends on how much sodium you have already eaten that day, how much you are sweating, and how long you are sweating for. But for everyday use — desk days, short workouts, travel, heat — most people do not need a salt bomb.
What public health guidance says about sodium
The Centers for Disease Control and Prevention (CDC) and the American Heart Association (AHA) recommend that most adults keep sodium under 2,300mg per day, and the AHA suggests an ideal limit closer to 1,500mg per day for many adults. Most of that sodium comes from packaged and restaurant food, not from the salt shaker.
The National Institutes of Health (NIH) notes that average U.S. intake is roughly 3,400mg a day — well above the recommended ceiling. That is why the sodium in a drink matters more than marketers used to admit.

How sodium shows up on electrolyte labels
The number to look for is milligrams per serving and the percent Daily Value (%DV). The FDA sets the Daily Value for sodium at 2,300mg, so every serving is measured against that ceiling.
- 88mg sodium = 4% DV. A light, everyday dose.
- 330mg sodium = 14% DV. Roughly the sodium in a small sports drink.
- 500mg sodium = 22% DV. Common in "hydration multipliers."
- 1,000mg sodium = 43% DV. Nearly half the daily ceiling in one stick.
If your day already includes a sandwich, chips, soup, or takeout, a 1,000mg stick pushes you closer to the limit before dinner. An 88mg stick leaves room for the food you actually enjoy.
Why "more sodium" became the default
Sports drinks were originally built for athletes sweating for hours. Salt-forward powders borrowed that logic: the harder you sweat, the more sodium you replace. The problem is that most people drinking electrolytes are not running marathons. They are at a desk, on a flight, in a yoga class, or walking the dog on a hot day.
For those days, a lower-sodium mix fits the overall diet better. It also tends to taste less salty, which means it needs less sugar or artificial sweetener to mask the salt.
When a high-sodium stick still makes sense
Endurance athletes, heavy manual laborers in heat, and anyone sweating for more than an hour at a time may need more sodium than a low-sodium stick provides. Those are the days to reach for a product designed for high sweat loss, or to follow the guidance of a coach or clinician.
If you are on a sodium-restricted diet or managing blood pressure, talk to your healthcare professional before adding any electrolyte supplement.
Balanced sodium, from a source you can check
Hydrate Heroes lists 88mg of sodium per stick — 4% DV — from mineral sea salt. The producer of our salt publishes a mineral analysis listing 90+ trace minerals, so the source is documented even if the brand name on the stick is new.
Combined with zero sugar, zero sucralose, organic stevia, and only 5 calories, the idea is simple: replace what you lose on an ordinary day without overloading what you do not need.
How to choose
- Check the serving size — is the sodium number for half a stick or the whole stick?
- Add the drink to your daily sodium budget, not your meal plan.
- Match the product to the day — high sweat, high sodium; low sweat, lower sodium.
- Look at sweeteners too; heavy salt is often hidden behind sugar or sucralose.
