No. An effervescent tablet is a format that dissolves in water. ORS, or oral rehydration salts, is a formulation used to replace fluid and salts in appropriate clinical situations. Two drinks can look similar in a glass and have different jobs.
If you are buying something because of diarrhoea, vomiting or possible dehydration, tell the pharmacist or doctor what is happening. Do not choose a vitamin drink simply because the pack mentions hydration, electrolytes or a refreshing flavour.
What the word effervescent tells you
Effervescent describes a preparation method. You dissolve the product as directed before drinking it. The ingredients and amounts can vary widely between products. One may be a vitamin supplement, another may have a different purpose entirely.
Read our effervescent-format guide if you are comparing routine nutrition products. For a medical need, start with the recommended formulation instead of choosing by the tablet's appearance.
A powder, tablet or liquid presentation does not by itself establish the intended use. The same applies to an orange flavour or the presence of one mineral name on the front.
What ORS is for
The World Health Organization describes oral rehydration solution as a way to replace water and electrolytes lost during diarrhoea. The formulation and how it is prepared matter to that purpose. This is different from adding a few vitamins to a drink for general nutrition. WHO: diarrhoeal disease and rehydration.
The word “salts” can sound like a reason to avoid it, but do not change a medically recommended rehydration plan based on a marketing comparison. If you have a condition that affects fluid or salt management, tell the professional advising you.

Compare the question each pack answers
| Pack information | Routine supplement | Oral rehydration product |
|---|---|---|
| Main question | What nutrients does a serving provide? | Is this the right product for the fluid-loss situation? |
| What to inspect | Full ingredients, amounts and cautions | Formulation, intended use and preparation directions |
| Water quantity | Follow that product's label | Follow the exact ORS preparation instructions |
| Suitability question | Doctor or pharmacist if relevant | Doctor or pharmacist, especially with illness or a vulnerable person |
Do not transfer a water quantity from one pack to another. A sachet intended for one volume should not be mixed into whatever size bottle happens to be available. Equally, do not copy ORS instructions onto a supplement tube.
The NHS explains that a pharmacist can advise on oral rehydration products when vomiting or diarrhoea causes fluid loss. Its advice concerns that situation; it is not an endorsement of a routine nutrition supplement. NHS: dehydration.
If you are feeling unwell, describe the situation
Instead of asking only “Which drink is best?”, tell the pharmacist about the vomiting or loose motions, how long it has lasted, whether you can keep fluids down and any medicines or relevant conditions. Say who the product is for. An adult's product choice should not be assumed suitable for a child.
Marked drowsiness, confusion, persistent dizziness, very little urine or an inability to keep fluids down need prompt medical advice. Do not keep trying wellness drinks while waiting for those symptoms to resolve. NHS: signs that dehydration needs urgent assessment.
A routine drink decision on a hot commute is a different question from fluid loss during illness. Our hydration article explains that distinction without treating every tired afternoon as a deficiency.
Where Nutrigap fits in this discussion
Herbadose presents Nutrigap as an effervescent food supplement. That description does not establish it as an ORS product or a treatment for dehydration. Inspect its current product information for the actual formula and directions, and do not substitute it for an oral rehydration product recommended by a health professional.
If you are shopping for general nutrition, compare the serving and full label. If you are shopping because someone is ill, resolve the care question first. What belongs in the glass follows from the purpose and the instructions, not from the fizz.
