Liquid electrolyte drops for work crews

Liquid electrolyte drops are a concentrated mineral liquid you add to water. They replace electrolytes lost in sweat and support hydration. Rapid Restoration Drops from JMAR contain magnesium, chloride, sodium and potassium, with no sugar and no calories. They sit beside water, rest and shade, never in place of them.

What are liquid electrolyte drops?

Liquid electrolyte drops are a concentrated mineral liquid. You add a small amount to water or another drink. They replace electrolytes lost in sweat and support hydration. They are a dietary supplement, not medicine and not a substitute for medical care.

An electrolyte is a mineral your body fluids need. Sodium, potassium and magnesium are the ones crews hear about most. MedlinePlus says sodium is an electrolyte, a mineral. A liquid electrolyte concentrate is the same idea in a small bottle or packet instead of a powder or a ready-to-drink bottle.

JMAR Solutions sells Rapid Restoration Drops in a 4 fl oz (120 mL) bottle and in single-serve packets. JMAR is based in Little Elm, Texas, and sells nationwide. The page for the bottle is Rapid Restoration Drops.

Why does water alone fall short on long hot shifts?

Because sweat carries out more than water. NIOSH says heat cramps often affect workers who sweat a lot during strenuous work, and that this sweating depletes the body’s salt and moisture levels. NIOSH also says that if sweating lasts for several hours, workers should drink sports drinks with balanced electrolytes.

Water is still the base. NIOSH says to drink 1 cup (8 oz) of water every 15 to 20 minutes for moderate work in the heat that lasts less than 2 hours. After that, electrolytes matter more, and a plan should cover them.

Shift length in heat What NIOSH says Where drops fit
Under 2 hours, moderate work 1 cup (8 oz) of water every 15 to 20 minutes Water is the main tool
Several hours of sweating Sports drinks with balanced electrolytes Drops add electrolytes to water
Any length Fluid intake should generally not exceed 6 cups per hour A ceiling on fluid intake

For the full plan, see the jobsite hydration plan and the heat stress prevention pillar. Our page on electrolytes versus water on long shifts goes into the choice.

What does sweat take out, and what goes back in?

Sweat takes out water and salts. Hydration means the body holds enough water and salts to work well, so replacing only the water does half the job.

Here is what the Rapid Restoration Drops label lists. Amounts are per 1 tsp serving.

Mineral Amount per 1 tsp serving
Magnesium 90 mg
Chloride 750 mg
Sodium 200 mg
Potassium 300 mg
Sulfate 40 mg

The label says 48 servings per 4 fl oz bottle. Other ingredients on the label: naturally derived seawater, electrolyte complex, purified water and non-GMO citric acid (from sugar beets). The label says no known allergens and gluten free. The drops have no sugar, no calories and no flavor.

What are the suggested uses?

This is the label’s own suggested use text, word for word:

“SUGGESTED USE: 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.*”

*These statements have not been evaluated by the Food and Drug Administration. Rapid Restoration Drops are a dietary supplement and are not intended to diagnose, treat, cure, or prevent any disease. In a medical emergency, always call 911 and seek professional medical care.

Heat stroke is a 911 emergency. Drops do not replace emergency care. Read more in the heat illness pillar.

Is more water always better? What is hyponatremia?

No. More water is not always better. Hyponatremia is low blood sodium. MedlinePlus explains that when the amount of sodium in the fluid outside cells drops below normal, water moves into the cells and they swell. This is a medical condition and needs a health care professional.

That is one reason NIOSH sets a ceiling: fluid intake should generally not exceed 6 cups per hour. NIOSH’s schedule is a cup every 15 to 20 minutes. That is also why a crew plan should say how much to drink and when, not just “drink more.”

Read the hyponatremia guide and the electrolytes 101 guide. If a worker shows confusion, seizures or loss of consciousness, call 911.

How do single-serve packets, bottles and bulk orders compare?

Pick the format by how your crew works. The bottle suits a truck, a break room or a water jug. Single-serve packets suit a pocket, a hydration pack or a lunch cooler. Bulk orders suit a program for many workers.

JMAR lists these formats and prices:

Format Price as published
4 oz bottle, 48 servings $50.00, or $45.00 a month subscribed
The RRD Bundle: 1 bottle and 15 single-serve packets $85.00
Single serves, 15 pack $37.50
Single serves, 50 pack $125.00
Single serves, case of 350 $700.00, listed by JMAR at $2.00 per packet

JMAR says subscribers “receive a free 2nd bottle with their subscription and can cancel at anytime.” For crew-wide quotes and government pricing, use bulk orders. To buy now, go to the shop.

JMAR describes the single-serve packet as the same liquid formula in a portable packet. It says you can take it straight or add it to any beverage, hot or cold, and follow with fluids.

How do crews use drops on the job?

Crews use them as part of a hydration routine, not as a stand-alone fix. The label says to add the suggested amount to any liquid and use it throughout the day. Keep water, rest and shade in place.

JMAR says the 4 oz bottle is built for use before, during and after a full workday, and that it is designed for hydration packs with no sticky residue. The single-serve packets are for crews on the move.

A short checklist for a safety manager:

  1. Start with the plan. Water, rest, shade, acclimatization and training come first. See our heat stress program guide.
  2. Read the label. Use the suggested use text above. Do not invent your own amounts.
  3. Check medical limits. Workers on low sodium diets, with heart problems or on medication should ask a health care professional first.
  4. Teach the signs. Everyone should know the signs of heat illness and that heat stroke means 911.
  5. Track what happens. Note who used what, and when, so you can judge the program.

NIOSH says to avoid salt tablets for heat cramps. A liquid electrolyte is not a salt tablet. Compare the options in our format comparison, including the page on drops vs salt tablets.

Who are the drops built for?

JMAR lists the groups it builds the single-serve packets for: construction and industrial crews, first responders and emergency teams, firefighters and wildfire crews, military and National Guard units, utility and infrastructure teams, athletes, and anyone working or training in heat or high exertion environments.

If your crew fits one of these, start with the industry page: construction, warehouse operations, industrial manufacturing, first responders or government agencies.

How do you store and carry them?

JMAR says the formula needs no refrigeration, and describes the single-serve packets as compact, shelf-stable and field-ready. It describes the bottle as built for hydration packs, with no sticky residue.

Practical points for a safety manager:

  • Keep a bottle at each water station and in each crew truck.
  • Give packets to workers who walk the site, drive or climb.
  • Keep the label with the product, so every user can read the suggested use.
  • Store as the label says. Ask JMAR if you need storage detail beyond the label.

What should you ask before buying any electrolyte product?

Ask six questions and read the label for the answers. They work for any brand, including this one.

  1. What is in it? Check the minerals and the other ingredients.
  2. How much sugar and how many calories? NIOSH says to avoid drinks high in sugar.
  3. What does the label say to do? Use the stated amounts only.
  4. Who tested and made it? Look for third-party testing and the facility line.
  5. Who should not use it? Ask a health care professional about low sodium diets, heart problems and medicines.
  6. How will crews carry and use it? A product nobody uses does nothing.

You can ask JMAR for a free sample to try these questions on a real bottle or packet.

What quality and manufacturing facts does JMAR publish?

JMAR publishes this line on its home page and product material: “3rd Party Tested | cGMP Certified | Vegan | Non GMO | Gluten Free | FDA Registered and Inspected Facility.” The label also says made in USA. Read the cGMP entry for what the term means.

“FDA Registered and Inspected Facility” describes the facility. It does not mean the FDA has approved or certified the product.

Read more about the company’s sourcing story on the made in USA page.

Frequently asked questions

Is water enough, or do I need electrolytes?

Water comes first, and NIOSH says to drink 1 cup (8 oz) every 15 to 20 minutes for moderate heat work under 2 hours. NIOSH adds that if sweating lasts several hours, workers should drink sports drinks with balanced electrolytes. Electrolyte drops replace electrolytes lost in sweat.

What are Rapid Restoration Drops and how do they work?

JMAR says Rapid Restoration Drops are a concentrated liquid form of essential minerals such as sodium, potassium, and magnesium. When added to water or any beverage, they help replenish electrolytes lost through sweat, aiding in hydration and supporting overall fluid balance in the body.

Do electrolyte drops contain sugar?

No. The Rapid Restoration Drops label lists no sugar and no calories, and the product is unflavored. JMAR also says the drops are Keto and diabetic-friendly. Read the label on the bottle for the full ingredient list.

Are Rapid Restoration Drops safe for daily use?

JMAR says they are safe for daily use to maintain consistent hydration. The label gives a daily support use of ½ tsp added to any liquid. Talk to a health care professional if you have a medical condition, are on a low sodium diet or take medication.

Can you drink too many electrolytes?

Follow the label's suggested use and do not make up your own amounts. The label gives one amount for emergency support and one for daily support. NIOSH says fluid intake should generally not exceed 6 cups per hour. Ask a health care professional about limits for your crew.

What is hyponatremia?

Hyponatremia is low blood sodium. MedlinePlus says when sodium in fluids outside cells drops below normal, water moves into the cells and they swell. Sweating can contribute. This is a medical condition. Call a doctor or 911 for confusion, seizures or severe symptoms.

Who makes Rapid Restoration Drops and where?

JMAR Solutions, based in Little Elm, Texas, sells them. The label reads made in USA. JMAR lists the quality line 3rd Party Tested, cGMP Certified, Vegan, Non GMO, Gluten Free, FDA Registered and Inspected Facility.
