/FAQ – Frequently Asked Questions

Just like nutritious food, hydration is absolutely foundational to our health and well-being. Many people take great care about what they eat, but they don’t pay much attention to hydration. This is like putting the cart before the horse. To be successful, any well balanced diet needs to start with a healthy level of hydration.

The short answer is No. There are two issues here. If you consistently allow yourself to get thirsty before you drink water, you are consistently exposing yourself to some level of dehydration, which is bad for your physical and mental health. Secondly, many beverages (particularly caffeinated soda & cola drinks, energy drinks, alcoholic drinks, and to a lesser extent, coffee and tea) have dehydrating and/or diuretic (increased urine formation) effects on the body. When you consume such beverages, you need to drink extra water to stay well hydrated.

Staying well hydrated depends on several factors, including the quantity and quality of water and beverages you drink, the water content of the foods you eat, intake of diuretic beverages and medicines, your body weight, your activity level, and also the weather! For example, hot weather increases water loss from your body due to sweating or perspiration. So the answer is not straightforward, and one size does not fit all! Please see this article for a more detailed discussion.

At a minimum, good quality drinking water should not have any significant level of toxic biological or chemical contaminants, and should have a significant level of healthy minerals, particularly calcium and magnesium. Unfortunately, it is not possible to be sure about the quality of drinking water simply by tasting it, looking at it, or even by filtering it. Some testing and/or information gathering is typically required. Please see response to next question for more info.

We agree that there is tremendous confusion about drinking water. There is a dizzying array of bottled water products available in stores, including purified water, vapor-distilled water, spring water, mineral water, electrolyte-enhanced water, alkaline water, alkaline-mineralized water, ionic water, infused water, vitamin water and so on. At the other end of the spectrum is plain old tap water. And then there are several options for purifying water at home, such as refrigerator filters, faucet filters, counter-top pitcher filters, distillation systems, water softening systems, reverse-osmosis filter systems; whole house filtration systems etc. So what do we recommend? Here are the main considerations that are useful to navigate through the confusion:

  1. It is a fact that municipal tap water and private well water can have many contaminants. As per reports from United States EPA, there are hundreds of known potential contaminants in water, and it is not possible to test for every new contaminant that is discovered. The majority of potential contaminants are not regulated, and are therefore not tested by authorities! It is also a fact that municipally treated water always has dissolved chlorine, chloramines, and/or other disinfection by-products, that react with other contaminants and often form carcinogenic derivatives at varying levels. The quality of tap water depends not only on the water source, but also the quality of water treatment, and the quality of pipes that bring the water into your home — it is not possible to constantly monitor all the variables. Therefore, it is best to use a NSF-certified filter to remove the most common contaminants from tap water or well water. However, please be aware that the vast majority of household filters are not capable of removing contaminants such as fluoride, nitrates and nitrites. Most municipal districts in the United States add fluoride chemicals to tap water, which is a very controversial practice and there is much evidence in recent scientific studies that water fluoridation does more harm than good (many countries have already banned fluoridation of water). Nitrates and nitrites are also common water contaminants due to extensive use of fertilizers in agriculture. These contaminants find their way into streams, rivers and the water table via agricultural run-off and seepage into the ground. If you want to remove fluoride, nitrates and nitrites, the most common options are to use a reverse-osmosis filter system, or a water distillation system combined with a carbon filter.
  2. It is also a fact that regular use of bottled water (including all types of mineral, spring, electrolyte-enhanced, alkaline, distilled, or purified bottled waters) is a very expensive choice, both for your wallet and for the environment. Further, the quality of bottled water can vary greatly, depending on the brand, the source water, the bottling operation, the quality of the plastic bottles, and the conditions under which the bottles are stored. If you use bottled water regularly, be sure to obtain and inspect the manufacturer’s water quality report. Please be aware however that most bottlers will conduct the minimum number of required water tests. They will typically not test for any unregulated contaminants, because they are not required to. In particular, we don’t know of any bottled water company which certifies or guarantees their bottled water to be free of plasticizers or other contaminants leaching from the bottles.
  3. If you use a relatively advanced water purification system at home (i.e. water softening system, distillation system, or a reverse-osmosis filter systems), in most cases you will get purified water of a consistent quality, but unfortunately such waters are always deficient in healthy minerals (these purification systems remove the good minerals along with the bad pollutants). If drinking pure water without agricultural or industrial pollutants is important to you, then using purified waters is usually the most cost-effective and probably the best choice for most people, provided that you add healthy mineral electrolytes back into the water. As far as we know, EMdrops is the first and only liquid product for adding essential mineral electrolytes (including calcium and magnesium) to drinking water, without any preservatives or chemical additives.
  4. The very best drinking waters have a good level of healthy dissolved minerals such as calcium and magnesium that are required by living organisms, while being free of disease-causing germs, toxic elements, disinfection by-products, agricultural and industrial pollutants etc. These healthy waters come from unpolluted natural sources such as high altitude mountain springs and deep underground aquifers. Unfortunately, such sources are rare in populated areas. Due to widespread pollution, the vast majority of people no longer have access to high quality pure drinking water, as defined above. This is the key reason why we at Watermins have pledged support to the ‘Environmental Working Group’ and ‘Fluoride Action Network’, since these organizations are passionate about keeping the environment clean, and are advocates of clean, safe, unpolluted drinking water.

Essential Minerals are minerals (elements found in the earth) that are essential for our survival and proper functioning. There are at least 15 different minerals in this category, and we normally get these minerals from food and water. The most commonly known essential minerals are calcium, iron, magnesium, potassium, sodium, chloride, and zinc.

Lesser known essential minerals are chromium, copper, iodine, manganese, molybdenum, phosphorus, selenium and sulfur. Emerging data indicates that additional minerals such as silica (or silicon) should be also on the list.

Electrolytes are elements or molecules that carry electrical charges in aqueous (water-based) solutions.  They are also referred to as ions — cations carry positive charge, and anions carry negative charge. In the context of water and beverages, electrolytes are ionic minerals that are dissolved within the water or beverage, as compared to regular minerals (found within various foods, tablets, capsules, powders and suspensions) that are in an electrically neutral form.


Health surveys consistently indicate that most people have deficient intake of calcium, magnesium, and/or potassium. However, sodium is an essential mineral that most people consume too much of.

For this reason, the EMDROPS formula includes calcium, magnesium and potassium, but no sodium.

Trace minerals are micronutrients that are required in very small amounts, generally less than 20 mg (milligrams) per day. There are several trace minerals that are considered essential for regular intake, including iron, iodine, selenium, and zinc. Since trace minerals are needed in trace quantities, it is relatively easy to get sufficient intake as long as we eat mostly healthy.

In contrast to trace minerals, there are some essential minerals needed by our bodies in relatively large amounts, and these are referred to as macro-minerals. It is relatively difficult to achieve a consistently good intake of macrominerals such as calcium, magnesium and potassium due to factors such as high consumption of processed or refined foods (these usually do not have a good or balanced proportion of essential macrominerals), low consumption of fruits and veggies, and and relatively inefficient absorption of minerals such as calcium and magnesium from solid foods.

Intake of essential minerals in an electrolyte form within water and beverages provides at least two different advantages: 1) the minerals get absorbed better and faster into our bodies, resulting in higher bioavailability and 2) the presence of electrolytes improves hydration significantly, because water molecules get pulled and absorbed along with electrolytes that are actively transported into cells.

Unfortunately, we have not come across sports drinks that provide a balanced proportion of the most important essential minerals. Most sports drinks are either completely lacking in calcium and magnesium, or have these essential macrominerals only in trace quantities.

Further, sports drinks are typically very rich in sodium (and sugars), and many do not have sufficient potassium to balance all that sodium.

From a health perspective, the worst ingredients in sports drinks are various artificial colors and flavors — these ingredients are added simply for their mass market appeal, and do not serve any health purpose. In fact, most artificial ingredients tend to have undesirable effects in the body if regularly consumed over time, something that most health-conscious moms have known for decades.

The answer is yes to all of the above questions.

However, it may not be necessary to add EMDROPS, in case your drinking water already has good levels of calcium and magnesium.

If you use a reverse-osmosis filter, a distillation system, a water softening system, or if you use purified bottled water, your water will not have any significant level of calcium and magnesium. Regular consumption of such waters is not advisable, since this may lead to calcium and magnesium deficiencies unless you eat a wonderfully perfect diet, and such deficiencies can cause many health problems.

Therefore, the best use of EMDROPS as a water enhancer is in the following cases:
a) distilled water
b) reverse-osmosis filtered water
c) softened water
d) purified bottled water
e) whenever your tap or well-water is naturally low in calcium and magnesium and
f) whenever you want to increase intake of essential minerals, particularly calcium & magnesium.

Add 1 to 2 drops of EMDROPS per cup (8 fl. oz.) of purified water, if you want a subtle and smooth taste to the water

Add 3 to 5 drops of EMDROPS per cup (8 fl. oz.) of purified water, if you want a more obvious mineral water taste

The number of drops would need to be adjusted, based on bottle capacity. Thus if you like 2 drops per cup, and your bottle holds 3 cups, then add 6 drops of EMDROPS when filling the bottle with water.



Add about 4 to 8 drops of EMDROPS per liter of purified water, if you want a subtle and smooth taste to the water.

Add about 10 to 20 drops (1 mL) of EMDROPS per liter of purified water, if you want a more obvious mineral water taste.


About 1 mL of EMDROPS per gallon of purified water for subtle taste, and about 1/2 teaspoon per gallon for a more obvious mineral water taste.
Please see more detailed ranges below:

Add about 16 to 32 drops (approx 0.8 to 1.5 mL) of EMDROPS per gallon of purified water, if you want a subtle and smooth taste to the water.

Add about 2 to 4 mL of EMDROPS per gallon of purified water, if you want a more obvious mineral water taste.

In general, it is best to start off at the low end of the range, and then add more EMDROPS in increments until you find the taste that works for you.


Yes, EMDROPS can be added to sports drinks, particularly if you want to boost the level of calcium, magnesium or potassium in your drink. Please note that most sports drinks provide plenty of sodium and sugar, but not calcium and magnesium. It is best to check the ingredients label of your sports drink to see if it provides any significant levels of calcium, magnesium, and potassium. If you have deficiencies of these electrolytes, that will negatively affect your health and performance.

Yes, EMDROPS is great for adding to drinking water for rehydration after any type of mild to moderate exercise by a healthy individual.

However, in cases of intense physical exercise with profuse sweating, severe dehydration, diarrhoea etc, it is important to add some table salt (sodium chloride) or sea salt (sodium chloride with trace minerals) to your drinking water, in order to replace the sodium lost in sweating. This is especially important for long distance endurance events. Please note that drinking large amounts of water quickly without sodium can cause hyponatremia, which can be extremely dangerous, or even lethal.

Yes, EMdrops can be used to make an excellent oral rehydration solution (ORS), when combined with purified or boiled water, salt (sodium chloride) and sugar. It is easy to make an ORS at home if you wish to avoid using store bought ORS. To 1 liter (or 1 quart) of purified or boiled water in a clean container, add 1/2 teaspoon (or 2.6 grams) of common salt (preferably sea-salt); 2 tablespoons (or 6 teaspoons) of sugar (preferably organic); and 20 drops (or 1 mL) of EMDROPS. This recipe is adapted from a WHO (World Health Organization) recommended recipe for making ORS at home.

Please note that the use of EMDROPS is optional — the main ingredients of a home-made ORS are water, sugar and salt. Adding EMDROPS provides beneficial calcium, magnesium and potassium electrolytes in addition to the salt and sugar. You may also optionally add the juice of a freshly squeezed lemon or lime for flavor. Use the ORS immediately after preparation, or store in the refrigerator for up to 24 hours.

Apart from adding accurate amounts of pure ingredients, the most important safety considerations in making an ORS at home are to use clean hands (preferably use gloves suitable for food handling), purified water (preferably distilled or boiled water), and very clean (preferably sterile) containers and mixing spoon for making and storing the ORS. The simplest way to “sterilize” a container at home is to immerse in boiling water for a few minutes, or to boil water in it (filled to near capacity).


“Mineralized Water” bought from a water store has some added minerals, mainly calcium and magnesium. We have frequently observed that water stores sell purified water (usually reverse-osmosis filtered water) for about 50 cents per gallon, and “mineralized water” or “electrolyte-enhanced water” is sold at about $1 to 2 per gallon. The level of added minerals is usually about 10 to 50 ppm (parts per million).

A single drop of EMDROPS in a full 8 oz (~240 mL) cup of purified water provides about 100 ppm of minerals (i.e. more than twice the concentration of typical “mineralized water”), at a far lower cost.


“Electrolyte-enhanced” bottled water has mineral electrolytes added to purified water . We have frequently observed that electrolyte-enhanced bottled waters of various brands (including “smart” water) have mineral electrolytes at about 20 to 30 ppm (parts per million).

A single drop of EMDROPS in a full 8 oz (~240 mL) cup of purified water provides about 100 ppm of mineral electrolytes (i.e. about 3 to 5 times the concentration of electrolytes found in typical electrolyte-enhanced bottled water), at a far lower cost.

EMdrops can be added to practically any beverage as a dietary supplement to boost intake of healthy mineral electrolytes, particularly calcium and magnesium. We recommend consuming wholesome beverages in moderation; healthy beverages that you know are good for your mind and body. Examples include various types of drinking water (our primary beverage), fresh fruit juice, green smoothie, tea, coffee, soup etc. Kindly note that what is healthy for one person may not be healthy for the next — to figure out what is healthy, you have to know yourself, along with your specific needs and constraints. For example, fruit juice is good for a healthy individual who needs a quick boost of energy, but is not good for a diabetic patient.

The suggested dose of EMDROPS as a mineral supplement is up to 1/2 teaspoon (or up to 2.5 mL), added to a cup of healthy beverage such as fruit juice, smoothie or soup. It can be also added to tea or coffee.

Please note that 1/2 teaspoon of EMDROPS provides 25% of the daily value of Calcium and Magnesium for an average healthy adult. We do not recommend adding more than this at one time, unless recommended by a doctor. The liquid mineral electrolytes in EMDROPS are better absorbed than solid minerals from tablets or capsules. If you take too much calcium and magnesium minerals at one time, the body cannot fully absorb these minerals, and some will simply go to waste.

When used as a water enhancer, EMDROPS is used in the same way for both adults and children i.e. add 1 to 2 drops per cup of water for subtle taste, and 3 to 5 drops per cup for a stronger mineral water taste.

When using EMDROPS as a calcium-magnesium supplement, it is best to discuss the dose with your child’s pediatrician, and customize based on your child’s needs. Please note that for supplement use, EMDROPS should be diluted in juice, smoothie, soup etc, based on child’s taste preference. If you add more than a few drops to water, the taste will be too strong and not very palatable. 

Here is additional info that is helpful to understand with respect to supplement use. The normal recommended intake of calcium for an adult of age 19 to 50 yrs is 1000 mg. The recommended calcium intake for children based on their age as follows: 200 mg for infants up to 6 months; 260 mg (6 to 12 months); 700 mg (1 to 3 yrs); 1000 mg (4 to 8 yrs); 1300 mg (9 to 18 yrs). So as you can see, as compared to adults, calcium requirement is much lower for infants and young kids, but for pre-teens and teenagers the requirement is higher than the standard intake for adults. An additional note: Adults >51 yrs also need higher calcium at about 1000 to 1200 mg, and the recommended calcium intake for pregnant and lactating women is between 1000 to 1300 mg.

Similar to calcium, requirements for Magnesium also vary based on age. The normal recommended intake of magnesium for an “average” adult is 400 mg. The recommended magnesium intake for children based on their age as follows: 30 mg for infants up to 6 months; 75 mg (7 to 12 months); 80 mg (1 to 3 yrs); 130 mg (4 to 8 yrs); 240 mg (9 to 13 yrs); and approximately between 310 to 420 mg for older kids and adults (the recommended amounts vary by gender).

Obviously, the requirements of calcium and magnesium will also vary based on other factors such as body weight, dietary preferences etc. For example, a child who is raised on a vegan diet (no animal products, including cow’s milk, yogurt etc) will need more calcium and magnesium supplementation, unless there is an excellent intake of fresh vegetables. Due to all of these complex considerations, it is best to discuss your child’s dose with a pediatrician and/or a dietary consultant. This applies to all dietary supplements, not just EMDROPS.

EMDROPS is much too concentrated to take directly. It always needs to be diluted in water or beverage.

If you take EMDROPS directly by mistake, you will most likely either spit it out by natural reflex, or you may gulp it down quickly due to the bitter taste of the concentrated product. If this happens, immediately drink plenty of water to get rid of the bitter taste.

These two minerals work well together; and are absorbed into the body through similar pathways. If you take excess amount of either one of these minerals, it can affect the body’s balance mechanisms for the other as well.

No, EMDROPS does not have Vitamin D. When supplementing with Calcium and Magnesium, please make sure that you do not have a Vitamin D deficiency. In case you have a Vitamin D deficiency, then it is best to take a Vitamin D supplement separately. Many such supplements are available, and the best ones are made with simple ingredients – such as Vitamin D drops in Olive Oil.

Many multivitamin/mineral formulas combine Vitamin D with calcium and magnesium. Although such combinations are convenient, unfortunately they often do not work very well, particularly due to absorption issues from tablets and capsules. Overall, a one size combination does not fit all, and it is rare to find a combination that is just right for you.

There are several reasons for this.

1. EMDROPS provides minerals that are more easily absorbed than typical tablets and capsules. So you need relatively less.

2. There is a limit to how much the body can absorb at a time, particularly for minerals such as calcium and magnesium. If you add too much, some proportion will usually pass through without absorption and go to waste.

3. If you add too much, your beverage may become unpalatable.

Overall, we believe that mineral supplements should not be taken in excess. Most mineral intake should normally come from a healthy diet, and supplements are best used only where needed, for example to guard against deficiencies if the diet is known to be lacking.

The following groups will benefit most from using EMDROPS as a calcium-magnesium supplement.

1. If you currently take calcium/magesium tablets or capsules, but find it difficult to swallow them, or if you dislike taking them — then you can take EMDROPS in a beverage of your choice.

2. If you currently take calcium/magesium tablets or capsules, but continue to show signs of calcium or magnesium deficiency, indicating absorption issues. EMDROPS is better absorbed since the minerals are in a fully dissolved liquid electrolyte form.

3. If you currently take any type of calcium/magnesium supplement (i.e. tablets, capsules, liquids, powders etc), but do not like the fillers, additives, colors, preservatives etc. EMDROPS has just pure mineral electrolytes in purified water, with no additives of any kind.

4. If your child needs a calcium/magnesium supplement, and you dislike giving them tablets and capsules (choking hazard etc), and you also dislike giving them artificially colored/flavored liquids full of preservatives. In such a situation, EMDROPS is a good choice because it can be added to any wholesome juice or smoothie. Do consult with a pediatrician though to ensure that you use the appropriate dose. General dose information for children can be found here.

5. If you are an older adult who has difficulty swallowing tablets & capsules, or if you have absorption issues, you can add EMDROPS to a healthy beverage of your choice.


Generally yes, IF you are using EMDROPS as a water enhancer, because water enhancer use involves very small amounts — which just a few drops of EMDROPS in your drinking water (this results in a healthy level of minerals that is often found in natural sources of drinking water). However, it is best to check with your doctor and/or pharmacist to be sure, particularly if you have any electrolyte balance issues. If you are using EMDROPS in larger amounts as a mineral supplement, always consult with a health care professional, before taking it along with prescription medicines.

In fact, if you are already taking prescription medication, you should follow this approach for any and all supplements – best to check first, unless you are a health professional yourself and are familiar with any incompatibility issues for your existing medication. Do not assume that you can combine various supplements and foods with prescription medicines.

In most cases, it should be OK, particularly if you are using EMDROPS as a water enhancer. That’s because use of EMDROPS involves adding just a few drops to your drinking water, which results in healthy levels of minerals that are often found in natural sources of drinking water.

However, if you are using EMDROPS in larger quantities as a mineral supplement, you should always read the labels and use directions of all the supplements to make sure you are not combining inappropriately. For example, it does not make sense to use EMDROPS as a mineral supplement, while taking another calcium/magnesium supplement. Similarly, it may not be useful to add EMDROPS to a beverage that is already rich in calcium and magnesium. It is also best to avoid taking a calcium-magnesium supplement at the same time as an iron supplement, because calcium and magnesium may compete with, and reduce the absorption of iron.

All ingredients in EMDROPS are GMP manufactured and comply with USP standards (United States Pharmacopoeia) to ensure high purity and quality. Further, all of the ingredients are classified by FDA to be GRAS (Generally Regarded as Safe).

EMdrops has the following “Essential/Electrolyte Minerals” listed below. All these minerals are classified by health authorities as “essential” because they cannot be manufactured by the human body and regular intake of these minerals in food and water is essential for human health:

Calcium (as ionic electrolyte Ca2+), Magnesium (as ionic electrolyte Mg2+), Potassium (as ionic electrolyte K+), and Chloride (as ionic electrolyte Cl-).  These electrolytes are dissolved in Purified Water USP. There are no other additives, colors, flavors, preservatives etc. For more details, including milligrams of each electrolyte per serving, please have a look at the “Supplement Facts” label information, available on the EMDROPS Product Overview page.

Sports drinks typically have electrolytes in the form of Sodium and Chloride (common salt), and may also include Potassium. EMDROPS formula does not have Sodium (on purpose), and it has calcium, magnesium, potassium, and chloride electrolytes. It does not have any Sodium, because most adults have excess sodium in their diets, which has been linked to cardiovascular issues. In fact, most adults also do not need to consume any sports drinks with sodium chloride, unless they experience significant sweating due to physical activity, or due to hot weather.

Yes, EMDROPS can be used to make or improve sports drinks, specifically to add Calcium, Magnesium and Potassium electrolytes. Please note that many sports drinks do not provide any significant level of Cacium and Magnesium, although these are essential mineral electrolytes that are necessary for hundreds of enzyme pathways in the body, and are needed for optimal performance. If your sports drink does not provide calcium and magnesium, just add a few drops of EMDROPS to it for a much improved drink.

It is also possible to skip sports drinks altogether. When you experience sweating, you can get excellent hydration by adding a pinch of table salt, and a couple of drops of EMDROPS to a cup of drinking water (preferably filtered). Follow up with some fresh fruit, healthy snack, protein bar etc, when you want some healthy nourishment to go along with the hydration. This way, you can avoid buying expensive sports drinks with artificial colors, sweeteners and preservatives that you don’t need, while getting the wholesome hydration and nourishment that you do need.

EMDROPS should be stored at room temperature (about 68 to 77 F; or 20 to 25 C). Periodic exposure to higher temperatures (e.g. during hiking/biking in hot weather; or leaving in a hot car) is OK. Brief exposure to cold conditions is also OK. However, do not store in fridge or freezer, since mineral crystals will form. If this happens, you may see cloudiness, particles or “snowflakes” in the product. This is normal and does not affect quality. Simply allow the bottle to reach room temperature and shake bottle for some time to dissolve the mineral crystals.

The shelf life of EMDROPS is at least two years. A “Best by” date is printed at the bottom of each bottle.


Simply allow the bottle to return to room temperature (this may take a few hours if the bottle was deeply frozen and is very cold), and shake the contents to help the particles go back into solution. To accelerate the process, the bottle may be placed in a cup of lukewarm water. Never heat the bottle in a microwave or stove since the bottle may melt.

EMDROPS is manufactured in the United States, in a FDA registered/approved facility that follows Good Manufacturing Practices (GMPs) to ensure quality and safety.
