Collection: O.R.S Hydration Tablets

Yes. O.R.S Hydration Tablets are designed to support rehydration during illness, including stomach bugs, vomiting, diarrhoea, and fever. The formula follows World Health Organisation guidelines for oral rehydration and is NHS-prescribed. For children under 3, you should only use O.R.S with the guidance or recommendation of a doctor, nurse or pharmacist.

For consistent hydration and day-to-day peak performance, you can use oral rehydration every day. You can also use oral rehydration whenever your body loses more fluids and salts than it takes in. Common situations include during or after illness (vomiting, diarrhoea, fever), intense exercise, hot weather, travel, dieting, fasting, hangovers, or simply when water alone isn't replenishing you effectively. O.R.S tablets help your body absorb fluids faster and more effectively than water alone.

O.R.S Hydration Tablets follow a clinically validated, pharmacist-formulated ratio of sodium, potassium, chloride, and glucose based on WHO oral rehydration guidelines. Many commercial electrolyte drinks lack the precise balance needed for rehydration, often because they contain excessive salt, high sugar, or no glucose. O.R.S is created by pharmacists and is the UK's No.1 Doctor-prescribed hydration tablet. It's also prescribed by the NHS, and is free from artificial colours, flavours, and preservatives.

Yes. O.R.S tablets are designed for everyday hydration support, not just illness or intense activity. They help maintain electrolyte balance during work, study, or daily life. Adults and children aged 3+ can use them daily as part of a healthy hydration routine. For everyday hydration, dissolve 2 tablets per 200ml of water. For sports or immune system hydration, dissolve 1 tablet in 500ml of water.

Yes. O.R.S Original and O.R.S Kids are suitable for children of all ages. For children under 3, use under a healthcare professional's supervision. O.R.S Kids comes in a child-friendly strawberry flavour and is paediatrician-recommended.

As recommended by WHO guidelines, O.R.S tablets contain a small functional dose of glucose (3.4-3.7g per 200ml in Original, 1.1g per 500ml in Sport) specifically included to enhance electrolyte absorption, helping your body hydrate faster. This is significantly lower than most sports drinks and is essential to how oral rehydration therapy works.

Yes. O.R.S tablets are popular during Ramadan, intermittent fasting, and calorie-controlled diets (including GLP-1 protocols) because they help maintain electrolyte balance while providing minimal calories. They help prevent the fatigue, headaches, and cramps that can result from electrolyte loss and dehydration during fasting.

O.R.S tablets use electrolyte-driven osmosis to help your body absorb water faster and more effectively than plain water. Most people feel the benefits within 30-60 minutes of drinking a dissolved tablet, though this varies depending on the severity of your dehydration.

Yes. All O.R.S tablets are vegan, vegetarian, gluten-free, dairy-free, nut-free, soy-free, halal, and kosher certified. They contain no artificial preservatives, colours, or flavours.
