Oral rehydration solution (ORS) is a glucose and electrolyte mix made to treat dehydration from diarrhea. Electrolyte drops are a dietary supplement that replaces electrolytes lost in sweat. They do different jobs. For vomiting or diarrhea, ask a clinician about ORS. For sweat on a hot jobsite, drops are the tool. Updated November 5, 20264 min read ## ORS has a medical job WHO describes ORS as a glucose-electrolyte solution used to treat dehydration from diarrhea. ## Sweat is a different loss Drops are a dietary supplement that replace electrolytes lost in sweat and support hydration. ## The sugar matters in ORS ORS pairs glucose with sodium on purpose. Rapid Restoration Drops list no sugar. ## Illness means call a clinician Vomiting, diarrhea and heat illness need medical advice. Heat stroke is a 911 emergency. ## What is the difference between electrolyte drops and oral rehydration solution? Oral rehydration solution is a glucose and electrolyte mix made to treat dehydration from diarrhea. Electrolyte drops are a dietary supplement that replace electrolytes lost in sweat. The two share some minerals. They do not share a purpose. The World Health Organization describes ORS as “an adequate glucose-electrolyte solution” given by mouth. It is a medical tool with a set recipe. A [liquid electrolyte concentrate](https://jmarsolutions.multisites.ai/glossary/liquid-electrolyte-concentrate) like Rapid Restoration Drops is a supplement you add to a drink. Read the entry on [oral rehydration solution](https://jmarsolutions.multisites.ai/glossary/oral-rehydration-solution) for the short definition. The rest of this page covers the choice a safety manager faces. ## How do ORS and electrolyte drops compare side by side? ORS is built for illness. Drops are built for sweat. The table sets the two side by side using what WHO and the Merck Manual say about ORS and what JMAR publishes about its drops. What to check Oral rehydration solution Rapid Restoration Drops (JMAR label and site) Main purpose Treats dehydration from diarrhea Dietary supplement that replaces electrolytes lost in sweat Key ingredients Glucose and sodium, in set amounts Magnesium, chloride, sodium, potassium, sulfate Sugar Glucose is part of the recipe No sugar, no calories Form Premixed solution or powder mixed with tap water Concentrated liquid added to any liquid Directions Product directions or a clinician The label’s suggested use Medical claims Used to treat dehydration None. Not for diagnosing, treating, curing or preventing any disease Sodium per serving Set by the recipe 200 mg per 1 tsp serving Price (JMAR) Varies $50.00 bottle, or $45.00 a month subscribed. 15 packets $37.50. 50 packets $125.00. Case of 350 $700.00 The key line is the second one. ORS uses glucose on purpose, because glucose helps the gut absorb sodium. The Merck Manual says ORS “should contain a combination of glucose and sodium.” Drops use no glucose, so they are not a replacement for ORS. ## Is a sports drink the same as ORS? No. In its chapter on oral rehydration therapy for children, the Merck Manual says: “Sports drinks, sodas, juices, and similar drinks do not meet these criteria and should not be used.” That sentence is about treating dehydration from illness in children. It still shows that ORS has its own recipe. NIOSH names sports drinks for a different job: heat cramps and sweating that lasts for hours. So the two products answer two different questions. Do not swap them at the cooler. A worker with diarrhea needs a clinician’s advice about ORS, and a worker sweating all day needs water, rest, shade and, as needed, electrolytes. For the sports drink side, see [drops vs sports drinks](https://jmarsolutions.multisites.ai/compare/electrolyte-drops-vs-sports-drinks). ## When is oral rehydration solution the better pick? ORS is the better pick when the problem is illness, not sweat. If a worker has vomiting or diarrhea, ORS is the product class that WHO describes for it. Ask a clinician first. NIOSH is clear about heat illness: for [heat exhaustion](https://jmarsolutions.multisites.ai/glossary/heat-exhaustion), take the worker to a clinic or emergency room, and call 911 if care is not available. Do not treat heat illness with any supplement alone. Heat stroke is a 911 emergency. Cool the worker and stay until help arrives. ORS is also a better pick for any worker told by a doctor to use it. Follow that advice over a catalog page. ## What should a crew plan for before illness strikes? Plan for two different problems. One is heat illness from work in the heat. The other is stomach illness that can strike anyone, on or off the job. They need different first steps. 1. Heat illness: move the worker to shade, give cool fluids, cool the body and follow the NIOSH first aid for the specific illness. 2. Vomiting or diarrhea: send the worker to a clinician and follow that advice, which may include ORS. 3. Confusion, fainting, seizures or loss of consciousness: call 911. Put each line on the crew card. A supervisor under stress should not have to decide from memory. Train the crew on the card before the hot season starts, and review it after any incident. ## When are electrolyte drops the right tool? Drops are the right tool for ordinary sweat loss on a hot day. The label says to add drops to any liquid and to follow with additional fluids. They add [sodium](https://jmarsolutions.multisites.ai/glossary/sodium), [potassium](https://jmarsolutions.multisites.ai/glossary/potassium), magnesium and chloride to a drink the worker already has. The label’s suggested use reads: “Emergency support\*: Add 1 tsp to a few ounces of any liquid. Follow with additional fluids. Repeat as needed. Daily support\*: Add ½ tsp, (just a squirt), to any liquid and use throughout the day to restore hydration and support endurance.\*” Rapid Restoration Drops are a dietary supplement. These statements have not been evaluated by the Food and Drug Administration. The product is not intended to diagnose, treat, cure, or prevent any disease. In a medical emergency, always call 911 and seek professional medical care. ## How should a supervisor choose between them? Match the tool to the cause. Sweat loss on a hot jobsite points to water, rest, shade and, if sweating lasts for hours, an electrolyte drink. Vomiting or diarrhea points to a clinician. Confusion, fainting or seizures point to 911. Write that into your heat plan so no one guesses in the moment. Use the [heat illness pillar](https://jmarsolutions.multisites.ai/heat-illness) for first aid steps. For what drops do and do not do, read [electrolytes 101](https://jmarsolutions.multisites.ai/guides/electrolytes-101). Back to the [comparison hub](https://jmarsolutions.multisites.ai/compare) for the other formats. If your program also covers cold work, the same rule holds: match the tool to the cause, and let a clinician decide when the cause is illness. ## Next step Book a [15-minute demo](https://calendly.com/jen-jmarsolutions/15-min-meeting) to see how drops fit a heat plan, or ask for a [free sample](https://jmarsolutions.multisites.ai/free-sample). ## Frequently asked questions ### Is oral rehydration solution the same as electrolyte drops? No. ORS is a mix of glucose and electrolytes designed for fluid loss from diarrhea, with set amounts of each. Rapid Restoration Drops are a dietary supplement that replace electrolytes lost in sweat and support hydration. They have no sugar, so they are not a glucose-electrolyte solution. ### Can adults use oral rehydration solution on a hot jobsite? ORS is sold for dehydration from illness, and WHO describes it for diarrhea in all age groups. A crew member with vomiting or diarrhea should ask a clinician. For ordinary sweat loss, NIOSH tells workers to drink water, and sports drinks with balanced electrolytes when sweating lasts for hours. ### Why does ORS contain sugar? ORS pairs glucose with sodium so the gut absorbs sodium better. The Merck Manual says ORS should contain a combination of glucose and sodium to take advantage of the sodium-glucose cotransport in the gut. That is why ORS is not sugar free. Drops serve a different goal. ### Do Rapid Restoration Drops treat dehydration? No. Rapid Restoration Drops are a dietary supplement. They replace electrolytes lost in sweat and support hydration. They are not intended to diagnose, treat, cure, or prevent any disease and are not a substitute for medical care. In a medical emergency, call 911. ### What should a supervisor do if a worker has diarrhea or vomiting? Get the worker out of the heat and in front of a clinician. Do not guess at a fix with a supplement. Heat exhaustion means a clinic or emergency room visit per NIOSH. If the worker is confused, faints or has seizures, call 911, cool the worker and stay until help arrives. ## Terms on this page - [Liquid electrolyte concentrate](https://jmarsolutions.multisites.ai/glossary/liquid-electrolyte-concentrate) - [Oral rehydration solution](https://jmarsolutions.multisites.ai/glossary/oral-rehydration-solution) - [Heat exhaustion](https://jmarsolutions.multisites.ai/glossary/heat-exhaustion) - [Sports drink](https://jmarsolutions.multisites.ai/glossary/sports-drink) - [Dehydration](https://jmarsolutions.multisites.ai/glossary/dehydration) - [Heat cramps](https://jmarsolutions.multisites.ai/glossary/heat-cramps) - [Heat stroke](https://jmarsolutions.multisites.ai/glossary/heat-stroke) - [Magnesium](https://jmarsolutions.multisites.ai/glossary/magnesium) - [Potassium](https://jmarsolutions.multisites.ai/glossary/potassium) - [Sodium](https://jmarsolutions.multisites.ai/glossary/sodium) ## Sources 1.
