Family Hydration Value Pack (£0.29 per tablet)

Life with a busy family means constant movement – school runs, sports clubs, family walks, colds and bugs, holidays and heatwaves.

Whenever fluid is lost through play, sport, travel, sweating or mild illness, water alone may not be enough to properly restore hydration and electrolytes, leaving children and adults feeling tired, headachy and low on energy.

O.R.S Hydration Tablets dissolve into water to create a low-calorie, great-tasting electrolyte drink that helps the whole family rehydrate quickly and stay hydrated for longer than with water alone.

Taste kids (and adults) love

Delicious, naturally flavoured tablets that turn plain water into a juicy, refreshing drink the whole family actually wants to finish.

  • Family-friendly flavours including blackcurrant, juicy orange and kid-approved strawberry, perfect for fussy drinkers.

  • Low in sugar (functional dose of glucose*) and calories, with natural colours and flavours designed to be gentle on stomach.

  • Parents tell us that adding O.R.S makes it easier to encourage kids to drink more water throughout the day.

* O.R.S products contain a small functional dose of glucose, essential to enhance electrolyte absorption and hydrate you faster.

What our customers say

  • We all know how fussy kids are and how gross re hydration sachets taste - well these apparently taste great according to the picky teen. She took them on world challenge so strong container and minimal size were important. these lived up to this. Although she was hesitant at first sip - she drank the rest happily. I would recommend these over other brands for that reason alone. They also got her back on track with hydration very quickly.

  • Recommended by a neighbour, I find the flavour of these so much better than others I have tried, in fact I actually enjoy it. I tend to drink a lot of coffee and not enough water so I have one of these daily and have noticed my skin is less dry. The tablets dissolve in the cold water very quickly and do not leave any lumps or bits. I gave some to a friend doing a very physical job in the recent heatwave and he said they really helped stop the headaches he was getting. I have also given them to family who have had tummy upsets and they found them very beneficial. Would highly recommend.
