> No South African electrolyte powder we checked in October 2026 publishes sodium per serving on retailer pages, so the best pick depends on price, sugar and sweetener. Lifestyle Electrolyte Fizzy and Biogen Electrolyte cost about R5 a serving; REVIVE Raw is the unsweetened option at about R13. Rehidrat is a medical rehydration salt, not a sports drink.

Key facts:
- Most South African electrolyte powders do not publish sodium per serving on retailer pages (October 2026).
- Biogen Electrolyte works out at about R5.17 a serving (R139–R155 for 30 sachets, Dis-Chem).
- REVIVE Raw (unsweetened, unflavoured) costs about R13.30 a sachet (R319–R399 for 30, Faithful to Nature).
- Rehidrat Oral has about 288 mg sodium and 12 g sugars per sachet by our calculation from SAHPRA product information; it is indicated for diarrhoea.
- Overdrinking, not low sodium intake alone, is the main cause of exercise-associated hyponatraemia.

## What is the best electrolyte powder in South Africa?

There is no clear winner on the one number that matters most, **sodium per serving**, because the retailer pages we reviewed (Dis-Chem, Clicks, Faithful to Nature, Takealot via PriceCheck) do not publish it for most products. The only quantified figure comes from the SAHPRA product information for Rehidrat, where we calculate roughly 288 mg of sodium and about 12 g of sugars per 14 g sachet. So we rank on what is verifiable: price per serving, sugar, sweeteners and how the product is positioned.

## How do the options compare?

October 2026 prices; per-serving cost is shelf price divided by sachets or tablets (our calculation):

| Product | Price (retailer) | Per serving | Sugar / sweetener | Sodium per serving |
|---|---|---|---|---|
| Biogen Electrolyte, 3 x 10 sachets | R139–R155 (Dis-Chem) | R5.17 | not published | not published |
| Lifestyle Electrolyte Fizzy, 10 tablets | R48–R53 (Dis-Chem) | R5.30 | not published | not published |
| Biogen Electrolyte Plus, 10 sachets | R72–R80 (Dis-Chem) | R8.00 | not published | not published |
| USN Purefit Zero Sugar Hydrator, 10 sachets | R100–R113 (Clicks via PriceCheck) | R10.00 | zero sugar | not published |
| Nutritech Hydrate, 10 x 9 g | R99.99 (Clicks via PriceCheck) | R10.00 | sugar-free | not published |
| REVIVE Raw, 30 sachets, unflavoured | R319–R399 (Faithful to Nature) | R13.30 | no sweetener | not published |
| Rehidrat Oral, 6 x 14 g | R108–R121 (Dis-Chem; Clicks) | R20.00 | about 12 g sugars | about 288 mg (calculated) |

## Which one for which job?

- **Best value for everyday sweat:** Biogen Electrolyte or Lifestyle Electrolyte Fizzy at about R5 a serving. Check the label for sodium before buying.
- **Cleanest label:** REVIVE Raw is unsweetened and unflavoured (sodium chloride from desert salt, magnesium malate, potassium chloride) but sodium per sachet is not published on the retailer page. Its stevia-sweetened sibling costs about R15 per sachet at list.
- **Sugar-free for office or light use:** USN Purefit Zero Sugar Hydrator or Nutritech Hydrate.
- **Gastro illness:** Rehidrat is an oral rehydration salt indicated for diarrhoea and gastroenteritis; use it as the leaflet says.

For fuelling long events you will also need carbohydrate; see [best energy gels in South Africa](/answers/best-energy-gels-in-south-africa/).

## How much sodium do you actually need?

There is no universal dose. Sweat sodium varies several-fold between athletes (commonly cited at roughly 10–90 mmol/L), and sweat rates run from about 0.5 to 2 L an hour. Practical guidance is to individualise from sweat tests; see [how much sodium per hour when running in South African heat](/answers/how-much-sodium-per-hour-running-in-south-african-heat/). For sessions under an hour or two, water and normal meals are usually enough; see [do I need electrolytes or just water](/answers/do-i-need-electrolytes-or-just-water/).

## What are the safety points?

Exercise-associated hyponatraemia is mainly caused by drinking too much fluid, and electrolyte products do not prevent it if you overdrink. High-sodium products are unsuitable for people with hypertension, heart or kidney disease or those on diuretics without medical advice. We found no verified third-party certification for any product here.

## When should you see a doctor?

Seek medical help for confusion, severe headache, repeated vomiting or seizures during or after endurance exercise. This is general information, not personal medical advice.

Under-18s should rely on normal food and water for sport. If you are pregnant, have kidney, heart or blood-pressure problems, or take regular medication, check your fuelling and sodium plan with a doctor or registered dietitian.
