Rehydration sachets vs electrolyte drinks
What each one is for — and when a low-sugar drink makes more sense.
Rehydration sachets are a pharmacy staple in South Africa. They do a specific job very well. For everyday hydration, a ready-to-drink option can fit your day better.

1. What is in a rehydration sachet?
Oral rehydration salts follow a WHO formula: sodium, potassium, citrate and glucose in exact amounts. The glucose isn’t there for taste — it helps the gut absorb sodium and water. [1] Mixed with the wrong amount of water, a sachet works less well, so follow the pack.
2. What does an electrolyte drink do differently?
A ready-to-drink electrolyte drink is made for routine hydration rather than treating illness. Electrolytes help the body manage fluid balance, which matters most after sweating. [3] It comes pre-mixed, so there is no measuring, and it is flavoured, so you actually finish it.
3. Why sugar matters for everyday drinks
The WHO advises keeping free sugars below 10% of daily energy, ideally under 5%. [4] Many sports drinks carry several teaspoons per bottle. Each Vitality Wellness drink is formulated with a maximum of 3g sugar per serving.

Frequently asked questions
What are rehydration sachets?
Rehydration sachets contain oral rehydration salts (ORS): a measured mix of sodium, potassium, citrate and glucose that you dissolve in clean water. They are designed to replace fluid and salts lost through diarrhoea or vomiting.
Are rehydration sachets better than an electrolyte drink?
For dehydration from diarrhoea or vomiting, a properly made ORS sachet is the right choice. For everyday top-ups — after exercise, heat or a night out — a low-sugar ready-to-drink electrolyte drink is more convenient and tastes better.
Can I use rehydration sachets every day?
ORS sachets are intended for treating dehydration, not as a daily drink. For everyday hydration, water plus a low-sugar functional drink when needed is a better routine.
Do electrolyte drinks contain a lot of sugar?
Many sports drinks do. AlcoHydrate™, VitaReload™ and MindAwake™ are each formulated with a maximum of 3g sugar per serving.
