Electrolyte drops are a different product. They are a diluted liquid you add to a drink, followed by more fluids. Neither replaces rest, shade and medical care. Updated November 5, 20264 min read ## NIOSH says avoid them CDC NIOSH heat cramp first aid includes one line: Avoid salt tablets. ## Drops go in a drink The label says to add the drops to any liquid and follow with additional fluids. Salt tablets are swallowed whole. ## NIOSH does not rule on drops The NIOSH page names salt tablets and sports drinks. It says nothing about liquid drops either way. ## Some workers need a doctor first NIOSH says to get medical help for heat cramps if the worker has heart problems or is on a low sodium diet. ## What does NIOSH say about salt tablets for heat cramps? CDC NIOSH first aid for heat cramps says to drink water, have a snack or a drink that replaces carbohydrates and electrolytes every 15 to 20 minutes, and “Avoid salt tablets.” It also says to get medical help if cramps last over 1 hour or the worker has heart problems or a low sodium diet. That is the clearest government line on this question. [Heat cramps](https://jmarsolutions.multisites.ai/glossary/heat-cramps) come from heavy sweating. NIOSH says sweating “depletes the body’s salt and moisture levels” and that “Low salt levels in muscles cause painful cramps.” So salt matters, but a bare salt tablet is not the answer NIOSH gives. The agency points to fluids, a snack or a drink that replaces carbohydrates and electrolytes, and rest. ## How do electrolyte drops and salt tablets compare side by side? They differ in form, in what they contain and in how you take them. The table shows what NIOSH says about salt tablets and what JMAR publishes about its drops. NIOSH does not review the drops, so the last row is blank on purpose. What to check Salt tablets Rapid Restoration Drops (JMAR label and site) Form Solid tablet, swallowed Concentrated liquid, added to any liquid What it supplies Salt (sodium chloride) Magnesium 90 mg, chloride 750 mg, sodium 200 mg, potassium 300 mg, sulfate 40 mg per 1 tsp serving Taken with fluids Depends on how the worker takes it Label says to follow with additional fluids Sugar and calories Not applicable None listed NIOSH heat cramp first aid “Avoid salt tablets.” Not addressed Medical claims None from JMAR None. A dietary supplement, not intended to diagnose, treat, cure, or prevent any disease 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 Be careful with the “what it supplies” row. Salt tablets give sodium and chloride. The drops add four minerals in a liquid, diluted in a drink. That is a different product with a different use, and NIOSH has not ruled on it. ## Does that mean electrolyte drops are safe to use for cramps? No claim of that kind is made here. The NIOSH advice names tablets, not liquid drops. What can be said is how the label tells you to use the drops: add them to a drink and follow with more fluids. 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. If a worker has heart problems or is on a low sodium diet, NIOSH says to get medical help for heat cramps. Ask a clinician before you give that worker any added sodium. In a medical emergency, always call 911 and seek professional medical care. Heat stroke is a 911 emergency. ## What is the right first aid for a worker with heat cramps? Follow the NIOSH steps for heat cramps. 1. Stop the work and move the worker to rest. 2. Give water and a snack or a drink that replaces carbohydrates and electrolytes. 3. Repeat every 15 to 20 minutes. 4. Avoid salt tablets. 5. Get medical help if cramps last over 1 hour, or if the worker has heart problems or is on a low sodium diet. Steps 1 to 3 are the same ones a crew can write on a card. Cramps can be a warning, so do not treat them as a small matter. NIOSH says heat cramps may also be a symptom of [heat exhaustion](https://jmarsolutions.multisites.ai/glossary/heat-exhaustion). Watch for headache, nausea, dizziness, weakness, irritability, heavy sweating and a high body temperature. For heat exhaustion, NIOSH says to take the worker to a clinic or emergency room. Confusion, slurred speech, seizures or loss of consciousness mean [heat stroke](https://jmarsolutions.multisites.ai/glossary/heat-stroke). Call 911, move the worker to shade, and cool the worker fast. The [heat illness pillar](https://jmarsolutions.multisites.ai/heat-illness) lists the steps. ## When are salt tablets the better pick? Rarely, and only on a clinician’s advice, because the general NIOSH line says to avoid them. If a doctor has told a worker to take salt, follow the doctor. A doctor knows the worker’s heart, medicines and diet. NIOSH’s line is general first aid for a crew, not a rule for each person. There is also a second risk on the other side. Drinking too much plain water can cause low sodium. A medical review says the main way to prevent exercise-associated [hyponatremia](https://jmarsolutions.multisites.ai/glossary/hyponatremia) is “to avoid overdrinking during exercise.” So the answer is never to push more of any one thing. Balance fluids, food, rest and, when sweating lasts for hours, an electrolyte drink. If a worker’s cramps repeat, do not guess. Send the worker to a clinician. Read the [hyponatremia at work guide](https://jmarsolutions.multisites.ai/guides/hyponatremia-at-work) for the other side of the risk. ## How do I put this in a crew plan? Write three lines in your heat plan. First, name water, rest and shade as the base. Second, list what your crew uses when sweating lasts for hours. Third, write down when to call a clinician and when to call 911. Then train the crew. Run a short toolbox talk and have each worker repeat the three lines back. Use the [jobsite hydration plan](https://jmarsolutions.multisites.ai/guides/jobsite-hydration-plan) as a template. See [drops vs sports drinks](https://jmarsolutions.multisites.ai/compare/electrolyte-drops-vs-sports-drinks) for the NIOSH-named option and the [comparison hub](https://jmarsolutions.multisites.ai/compare) for other formats. ## Next step Book a [15-minute demo](https://calendly.com/jen-jmarsolutions/15-min-meeting) to walk through a heat plan with JMAR, or request a [free sample](https://jmarsolutions.multisites.ai/free-sample). ## Frequently asked questions ### Should workers take salt tablets for heat cramps? CDC NIOSH first aid for heat cramps says to avoid salt tablets. It says to drink water and have a snack or a drink that replaces carbohydrates and electrolytes every 15 to 20 minutes. It also says to get medical help if cramps do not subside within 1 hour. ### Are electrolyte drops the same as salt tablets? No. A salt tablet is a solid dose of salt. Rapid Restoration Drops are a concentrated liquid with magnesium, chloride, sodium and potassium that you add to a drink and follow with more fluids. NIOSH does not review the drops. They are a dietary supplement. ### What causes heat cramps? NIOSH says heat cramps usually affect workers who sweat a lot during strenuous activity. The sweating depletes the body's salt and moisture levels, and low salt levels in muscles cause painful cramps. Heat cramps may also be a symptom of heat exhaustion, so watch for other signs. ### When should a worker with cramps get medical help? NIOSH says to get medical help if the worker has heart problems, is on a low sodium diet, or has cramps that do not subside within 1 hour. If the worker is confused, faints, has seizures or very high body temperature, call 911. That is heat stroke until a clinician says otherwise. ### Can I use salt tablets if a doctor told me to? Follow your doctor. NIOSH advice is general first aid for workers with heat cramps. A clinician who knows a worker's health, medicines and diet can give personal sodium advice that overrides a general rule. Tell the supervisor, so the crew's heat plan fits. ## Terms on this page - [Heat exhaustion](https://jmarsolutions.multisites.ai/glossary/heat-exhaustion) - [Hyponatremia](https://jmarsolutions.multisites.ai/glossary/hyponatremia) - [Toolbox talk](https://jmarsolutions.multisites.ai/glossary/toolbox-talk) - [Electrolyte](https://jmarsolutions.multisites.ai/glossary/electrolyte) - [Heat cramps](https://jmarsolutions.multisites.ai/glossary/heat-cramps) - [Heat stroke](https://jmarsolutions.multisites.ai/glossary/heat-stroke) - [Hydration](https://jmarsolutions.multisites.ai/glossary/hydration) - [Magnesium](https://jmarsolutions.multisites.ai/glossary/magnesium) - [Potassium](https://jmarsolutions.multisites.ai/glossary/potassium) - [Sodium](https://jmarsolutions.multisites.ai/glossary/sodium) ## Sources 1.
