Hydralyte Colour-Free Lemonade Electrolyte Solution 1 Litre – Oral Rehydration for Dehydration, Illness & Sport

Hydralyte is a scientifically formulated oral rehydration solution (ORS) that replaces fluids and electrolytes lost due to vomiting, diarrhoea, fever, heavy sweating, or strenuous physical activity. The lemonade flavour, colour-free formula is particularly suitable for those sensitive to artificial colours or additives. Hydralyte's electrolyte balance is designed to match the WHO-recommended osmolarity for optimal absorption — replacing fluids faster than water or sports drinks alone.

• WHO-recommended electrolyte osmolarity for optimal rehydration
• Replaces sodium, potassium, chloride, and glucose lost during illness
• Colour-free, refreshing lemonade flavour
• Suitable for all ages including infants and children (adult supervision)
• 1 litre — ready to drink, no mixing required

Frequently Asked Questions

Why is Hydralyte better than water or sports drinks for rehydration during illness?

Water alone does not replace the electrolytes (sodium, potassium, chloride) lost during vomiting, diarrhoea, or fever — and drinking water without electrolytes can actually dilute remaining electrolytes further. Sports drinks are too high in sugar and too low in sodium for effective oral rehydration during illness. Hydralyte's formulation matches WHO oral rehydration solution standards — the specific sodium-to-glucose ratio activates the sodium-glucose co-transporter in the small intestine for rapid, efficient fluid absorption that plain water or sugary drinks cannot match.

When should I use Hydralyte?

Hydralyte is appropriate for: gastroenteritis (vomiting and diarrhoea), fever (which increases fluid and electrolyte loss through sweating), dehydration from heat, strenuous exercise or sport (post-activity rehydration), travel-related dehydration, morning sickness in pregnancy, hangover-related dehydration, and when oral fluid intake has been reduced due to illness.

How much Hydralyte should I drink when ill?

The general guideline for adults with active vomiting or diarrhoea is to sip 200–400ml per hour, replacing approximately 150–200ml after each vomiting or diarrhoea episode. For children, consult age-appropriate dosing guidelines on the label. If dehydration is severe (no urination for 8+ hours, extreme lethargy, sunken eyes in infants), seek medical attention.

Is Hydralyte suitable for infants and young children?

Yes. Hydralyte is suitable for infants from birth under medical or parental supervision. For infants under 6 months with illness, always consult your GP before starting any oral rehydration. For older babies and toddlers, follow age-appropriate dosing on the label. Hydralyte is one of the most recommended brands for infant gastroenteritis management.

Can Hydralyte be used during pregnancy?

Yes. Hydralyte is safe during pregnancy and is often recommended for morning sickness-related dehydration and electrolyte replacement. The colour-free, mild lemonade flavour is typically well tolerated even with pregnancy-related nausea. Consult your midwife or GP if you have severe dehydration during pregnancy.
