South African runners sweat more than their European counterparts. Our climate demands it. Yet most hydration advice you'll find online comes from cooler countries or brand sites pushing one product. We stock seven different electrolyte solutions because no single option works for every athlete, every condition, or every family member. This guide breaks down exactly what each one does and which runner, kid or weekend warrior it suits best.
Why Electrolytes Matter More in South Africa
A training run in Johannesburg at 28 degrees is not the same as a training run in Manchester at 15. You lose roughly 1 to 1.5 litres of sweat per hour in SA summer conditions. That sweat isn't just water. It carries sodium, potassium, magnesium and chloride. Lose enough of those and your muscles cramp, your heart rate spikes, and your pace falls off a cliff.
According to the Sports Science Institute of South Africa, athletes training in hot conditions need between 500mg and 700mg of sodium per litre of fluid replaced. That's well above what most tap water or plain sports drinks deliver. It's also why a Comrades runner can finish a race more dehydrated than when they started, despite drinking at every water table.
Hydration isn't only a runner's issue. SA school kids are notoriously under-hydrated during afternoon sports. Our teenage athletes finish hockey practice at 5pm in 30-degree heat having drunk half a water bottle. That's how kids end up fainting on the field.
Do You Need Electrolyte Drinks or Is Water Enough?
For efforts under 60 minutes in mild conditions, water is fine. Your body has enough stored electrolytes to cover a casual park run or a short gym session.
Above 60 minutes, or in SA heat, plain water starts to work against you. You keep drinking, you keep sweating, and the salt you lose isn't being replaced. That's when cramping hits. That's when you feel inexplicably exhausted despite hydrating. The American College of Sports Medicine recommends electrolyte drinks for any endurance activity lasting more than an hour, and for any exercise in hot or humid conditions regardless of duration.
The short answer: water for easy days, electrolytes for long days and hot days. Both have a place. Neither replaces the other.
The Best Electrolyte Drinks Available in South Africa
We've tested every product below on ourselves, our kids, and our ultra-running friends. No affiliate links to brands we don't stock. Every option delivers real electrolytes in the right ratios, but each one suits a different use case. Here's how they compare at a glance.
| Product | Best for | Sugar | Price |
|---|---|---|---|
| 32Gi Hydrate Tabs | Everyday effervescent hydration | Low | R190 / 20 tabs |
| SIS GO Hydro | Zero-calorie hydration | Zero | R230 / 20 tabs |
| High5 Zero | Light training | Zero | R215 / 20 tabs |
| DripDrop ORS | Heat exposure and recovery | Half a sports drink | R175 / 8 sachets |
| Kokee Pouches | Active women, daily | 75% less than sports drinks | R259 |
| Kokee Rookee | Active kids, school sport | Low | R469 |
| Tailwind Endurance Fuel | All-in-one endurance fuel and hydration | 50g carbs (fuel, not low-sugar) | R62 / serve |
How we tested. Every product here has been used by our own family and running circle through SA summers, Comrades and Two Oceans build-ups, school tournaments and Karoo trail days. We checked each label against the 500 to 700mg sodium per litre that SA heat demands, drank them on real long runs to judge taste fatigue and gut comfort, and only kept the ones we'd hand to our own kids. We stock all seven, so we have no reason to push one over another beyond what actually works.
32Gi Hydrate Tabs: Best Everyday Effervescent
The 32Gi Hydrate Tabs are proudly South African and built for our conditions. Drop one into 500ml of water, wait 30 seconds, and you've got a hydration drink with sodium, potassium and magnesium in the right ratio for SA climates.
At R190 for 20 tabs, that works out to R9.50 per bottle. The flavours are light. Not the overwhelming sweetness of traditional sports drinks. Our team uses these for daily training in summer and packs them for weekend races. A tube fits in any backpack or race belt.
Best for: Daily training hydration. Long Saturday runs. Runners who want local, tested-in-heat electrolytes without the sugar load.
SIS GO Hydro: Best Zero-Calorie Tablet
The SIS GO Hydro comes from Science in Sport, the same brand trusted by pro cycling teams. At R230 for 20 tabs, it's slightly pricier than 32Gi but carries the research pedigree of a global performance brand.
Zero calories, zero sugar. Each tablet delivers 250mg of sodium, 64mg of potassium, and a small dose of magnesium. That makes it ideal if you're watching your calorie intake or running fasted sessions where you don't want extra carbs confusing your training.
Best for: Calorie-conscious athletes. Fasted morning runs. Runners who already get carbs from gels and only need electrolyte replacement.
High5 Zero Hydration: Best for Light Training
The High5 Zero Hydration tabs are a solid middle option at R215 for 20 tabs. Zero calories, berry flavour that's genuinely drinkable, and electrolyte levels suited to shorter efforts.
We reach for these during everyday training sessions under 90 minutes where you need replacement but don't need the heavier dosing of an endurance product. Easy on the stomach, easy on the wallet.
Best for: 45 to 90-minute training runs. Gym sessions in summer. Lighter hydration needs.
DripDrop ORS: Best for Heat Exposure and Recovery
The DripDrop ORS Sachets are different from the tablets above. This is a medical-grade oral rehydration solution developed by a doctor to treat severe dehydration. Think dehydration after a stomach bug, heat exhaustion, or a long race where you've pushed too hard for too long.
At R175 for 8 sachets (R22 each), it's a premium product for specific situations. DripDrop absorbs 2 to 3 times faster than water because of its precise electrolyte-to-glucose ratio. The formula is WHO-aligned. You're getting a clinically-proven rehydration, not a sports drink.
Keep a sachet in your race bag, your school sports kit, and your travel bag. We use them after Comrades training runs, on 40-degree Karoo trail days, and when our teenagers come home pale-faced from a tournament.
Best for: Severe dehydration recovery. Heat exhaustion. Post-illness rehydration. Ultra racing support and emergencies.
Kokee Hydration Pouches: Best for Women
Most sports hydration products were formulated for male athletes. The Kokee Hydration Pouches are different. Built around natural coconut water electrolytes with 75% less sugar than standard sports drinks, they target hydration needs specific to active women including perimenopausal athletes.
At R259 per pouch pack, Kokee is a premium option. But the coconut water base delivers potassium naturally, and the lower sugar content matters if you're managing weight, blood sugar, or hormonal hydration shifts. Our Hannah swears by these during long Midlands trail runs.
Best for: Female endurance athletes. Active women over 40. Runners who want clean-label hydration without artificial sweeteners.
Kokee Rookee: Best for Active Kids
Kids aren't small adults. Their sweat rates, electrolyte needs, and tolerance for artificial flavours are all different. Kokee Rookee Hydration Pouches are designed specifically for junior athletes at R469 per pack.
Natural electrolytes, kid-friendly flavours, and dosing that actually matches what a 12-year-old cross-country runner needs. These live permanently in our active family essentials box for school sports days, tournament weekends, and the kind of 34-degree afternoon hockey practice that wrecks a hydration plan.
Best for: School cross-country. Tournament weekends. Parents sick of handing kids sugary sports drinks.
Tailwind Endurance Fuel: Best All-in-One for Endurance
If you're a trail runner, ultra athlete, or long-distance cyclist, the Tailwind Endurance Fuel deserves a place on this list even though it isn't a pure electrolyte drink. At R62 per sachet, each serving delivers 50g of carbs alongside a full electrolyte profile of sodium, potassium, calcium and magnesium.
That makes it a hybrid: hydration, fuel and electrolytes in one bottle. For events over three hours, it replaces gels, rehydration solutions and sports drinks in a single solution. Simple sugars absorb quickly without sitting heavy. Our trail runners use Tailwind as their primary bottle fuel during anything over 25km.
Best for: Ultra training and racing. Trail runners carrying hydration packs. Athletes who want one product instead of juggling three.
Electrolyte Tablets vs Sports Drinks: What's the Difference?
The two aren't interchangeable. Here's the practical breakdown:
Electrolyte tablets (32Gi, SIS, High5): Zero or low calorie. You add them to water. You control the dose. Great for training, weight management, or runners who already fuel with gels.
Ready-mixed sports drinks (Powerade, Energade): Carb-loaded for quick energy. Higher sugar content. Convenient at a petrol station pit stop but excess calories for anyone not racing hard.
Oral rehydration solutions (DripDrop): Medical-grade, highest absorption rate. Used for actual dehydration treatment, not casual hydration.
Endurance hybrid fuels (Tailwind): Carbs plus electrolytes for long efforts. Replaces multiple products.
For daily SA training, we lean on tablets. For races over three hours, hybrid fuel. For rescuing a kid who's been in the sun too long, ORS. No single product does it all.
How to Pick the Right Electrolyte Drink for You
Stop overthinking it. Match the product to the situation:
Daily training in SA summer: 32Gi Hydrate or High5 Zero. Affordable, effective, easy.
Fasted or calorie-controlled training: SIS GO Hydro. Zero-calorie, research-backed.
Long races (half-marathon and up): Tailwind if you want one bottle. Tablets plus gels if you prefer separate products.
Kids at sports: Kokee Rookee, every time. Pack DripDrop as a backup.
Women's endurance: Kokee for clean electrolytes, lower sugar, natural coconut water.
Post-race or heat emergency: DripDrop ORS. Keep it in your kit.
