Sugar-Free Electrolytes — Complete Guide 2026
Complete guide to sugar-free electrolytes — who actually needs them, what to look for, and how the Swedish market is built differently than global sports-drink categories. Facts, not marketing.
Sugar-free electrolytes in 30 seconds
Electrolytes are minerals — sodium, potassium, magnesium, chloride — that your body loses through sweat. You can replace them with or without added sugar. Sugar-free electrolyte powders exist because most people don't actually need the carbs that traditional sports drinks carry. Training under 90 minutes, daily hydration, hangover recovery, sauna, fasting windows — all are electrolyte-replacement problems, not energy-replacement problems.
The short rule: if your workout is over 90 minutes at hard intensity, extra carbs help. Anything shorter or non-training, sugar just adds calories without helping hydration.
Heey!'s Hydrate Series is 100% vegan electrolytes with no added sugar, made in Sweden. 240 g bag (40 servings) at 279 SEK, or 180 g / 30-stick pack at 329 SEK. Three variants: Hydrate & Glow, Hydrate & Focus, Hydrate & Defend.
Why sugar in sports drinks exists (and when it's wrong)
The original purpose of carbohydrates in sports drinks was to fuel prolonged endurance exercise — glycogen replacement during marathons, long rides, triathlons. Your muscle glycogen holds about 90 minutes of hard effort. Past that, intake of 30–60 g carbs/hour measurably improves endurance.
The problem: most people drinking sports drinks aren't doing ultra-endurance. They're doing a 45-minute lift, a hot yoga class, or just hydrating after a sauna. In those situations, 14–30 g of added sugar isn't helping — it's just calories.
Sugar-free electrolyte powders skip the carb solution entirely and focus on the mineral replacement that's actually needed day-to-day.
Who actually needs sugar-free electrolytes?
- Daily hydration in hot climate or heavy water drinkers — replacing 2–3 liters of water without electrolytes can dilute your mineral balance. A single serving in your day covers it.
- Training under 90 minutes — lifting, HIIT, CrossFit, shorter runs. You're running on stored glycogen. Extra sugar during a 45-min session is wasted calories.
- Hangover recovery — alcohol dehydrates and depletes sodium, magnesium, and potassium. Another round of sugar on top usually makes the morning worse, not better.
- Sauna, heat exposure, fever, stomach bug — sweat and fluid loss are mineral-heavy. The body doesn't need sugar to rehydrate.
- Intermittent fasting — carbs break the fasted state. Electrolytes don't, so fasting-window hydration stays clean.
- Low-carb or keto diets — added sugar breaks the macro structure of these diets. Electrolytes are particularly important on low-carb because the kidneys excrete more sodium.
- People who hate sweet drinks — simple preference reason. Good electrolyte powders taste subtle, not candy-sweet.
What good sugar-free electrolytes should contain
| Criterion | Good product | Warning sign |
|---|---|---|
| Sodium per serving | 300–1000 mg (depending on sweat level) | Under 100 mg = too little to matter |
| Potassium | 100–300 mg per serving | Missing entirely = unbalanced |
| Magnesium form | Glycinate, bisglycinate, citrate, or malate | Magnesium oxide (low absorption, stomach issues) |
| Sweeteners | Stevia, steviol glycosides, monk fruit | Aspartame, high-dose artificial sweeteners |
| Colorants | Natural (beetroot, beta-carotene) | Artificial dyes (E102, E110, E133) |
| Manufacturing | Transparent origin, local or EU-regulated | "Distributed by" without production country |
How the Swedish market is built (context)
Sweden's hydration-drink category doesn't map 1:1 to global sports-drink categories. Understanding the landscape helps you pick the right product for your actual need:
- Energy drinks (NOCCO, Celsius, Vitamin Well) — caffeine-based, often with BCAAs or vitamins. Not electrolyte-focused despite the functional drink positioning. Some are sugar-free, some aren't.
- Carb-focused sports drinks (Vitargo, traditional sports drinks on pharmacy shelves) — carbohydrate-first, designed for endurance performance. Contain carbs by design.
- Pharmacy rehydration salts (Resorb, Semper, generic oral rehydration) — clinical formulations mostly for stomach bugs and pediatric rehydration. Not designed for training.
- Sugar-free electrolyte powders (a smaller category in Sweden) — mineral-first, zero or near-zero sugar, designed for daily hydration and training under 90 minutes. This is where Heey! Hydrate sits.
If you're choosing between the categories: energy drinks solve "I need focus/caffeine," carb sports drinks solve "I'm doing 90+ min endurance," rehydration salts solve "I'm recovering from illness," sugar-free electrolytes solve "I sweat or hydrate a lot and want minerals without extra sugar."

Frequently asked questions
Q: Do I need electrolytes if I only drink water?
A: Depends on your sweat volume and water intake. If you drink 2+ liters of water daily and sweat moderately (training, hot climate, sauna), water alone can dilute your electrolyte balance over time. One serving a day typically covers it.
Q: Are sugar-free electrolytes safe for daily use?
A: Yes, at recommended doses. Heey! Hydrate delivers 75 mg magnesium (20 % NRV) per serving — well within safe daily intake. Sodium and potassium are within typical daily ranges. Always follow the label and don't exceed recommended servings.
Q: Can I take electrolytes while fasting?
A: Yes — this is one of the main reasons sugar-free formulas exist. No carbs means no insulin response, so fasting-state metabolism isn't interrupted. Electrolytes actually reduce the headaches and fatigue many people experience during extended fasts.
Q: What's the difference between sugar-free electrolytes and pharmacy rehydration salts?
A: Rehydration salts (Resorb, Semper, generic ORS) are formulated for clinical dehydration — typically higher glucose-to-salt ratio to drive absorption during illness. Electrolyte powders are formulated for general hydration and training without the clinical flavor or composition. Different tools for different jobs.
Q: Do sugar-free sweeteners like sucralose or stevia cause problems?
A: At the doses used in electrolyte products, both are considered safe by EFSA and Livsmedelsverket. Heey! Hydrate uses sucralose and steviol glycosides in small amounts for flavor. If you're sensitive to sweeteners, start with half a serving and see how you feel.
Q: How much sodium do I actually need after training?
A: A typical hour of sweaty training loses 300–700 mg sodium. Heavy sweaters in hot conditions can lose 1000+ mg per hour. Heey! Hydrate delivers 322–424 mg sodium per serving depending on variant, covering most general sessions. Ultra-endurance athletes may need two servings during long efforts.
Q: Can I mix Heey! Hydrate with other supplements?
A: Yes. Common combinations: Hydrate + Plant Protein post-training, Hydrate + Creatine Monohydrate pre-training. The flavors of Hydrate & Glow (watermelon, passionfruit) and Focus (lemon) mix well with protein.
