Are you concerned about the mineral content of reverse osmosis water? With our straightforward step-by-step instruction, you can learn how to remineralize water and replenish it with healthy calcium and magnesium.
Remineralization of reverse osmosis water
Reverse osmosis systems remove practically all dangerous elements from water, resulting in a filtered result devoid of pollutants such as chlorine and lead.
However, reverse osmosis technology is so efficient that it removes all of the good stuff from the water as well. That is, by saying goodbye to hazardous compounds, you are also purifying the water of beneficial minerals such as calcium and magnesium.
Should you keep drinking RO water? Is it necessary to remineralize the water before drinking it? We take a closer look at reverse osmosis water and answer these and other questions.
Reasons you may want to remineralize RO water
- Many diets are terribly mineral deficient, and in these circumstances, water can compensate the mineral deficiency from food.
- Pure water cannot be kept pure for long since it must dissolve some carbon dioxide from the environment. When carbon dioxide is dissolved, it becomes somewhat acidic and the pH decreases. Adding minerals back into water successfully raises the pH if you want to drink alkaline water.
- If you dislike the taste of pure water, remineralization can help to restore some of the familiar flavor.
Problems with drinking demineralized water
While health experts are divided on the effects of drinking demineralized water, there is some concern about long-term ramifications.
The World Health Organization has identified many potential health consequences of drinking water depleted of practically all minerals.
They include gut mucous membrane damage and a detrimental impact on numerous biological systems as a result of a lack of essential minerals like calcium and magnesium.
When demineralized water is used in cooking, it might diminish the mineral content already present in food, thereby reducing your overall mineral intake.
There’s also the matter of acidity to consider. Demineralized water is slightly acidic because it lacks mineral ions, which are the primary contributors to water’s alkalinity.
Drinking acidic water is typically thought to be less healthier than drinking alkaline or pH balanced water.
Even if you are not concerned about the potential health repercussions of drinking demineralized water, the flavor may turn you off, especially if you are accustomed to drinking tap water or bottled mineral water.
The lack of minerals imparts a bland, unpleasant taste to the water.
So, should you quit drinking RO water altogether?
Most emphatically not. You may have peace of mind while drinking safe RO purified water and getting your daily dose of necessary minerals.
The effects of consuming demineralized water are still being studied. You will not be deficient if you drink mineral-free RO water. Many health experts agree that as long as you consume a well-balanced diet, you should be able to receive all of your important minerals through food.
Drinking demineralized water, however, may pose additional hazards to some people, such as those with certain health issues. As usual, see your doctor if you have any concerns about drinking demineralized water or manually adding minerals back into the water.
What happens to the water when Reverse Osmosis Is used?
You’ve probably heard of reverse osmosis, but do you know what it is and what the end result is?
Here’s a basic rundown of the procedure.
The membrane and filters in a RO filtering system collect the water before it is poured out. It’s filtration at its most fundamental, although on a small scale.
The RO membrane allows water to pass through and into your glass but rejects anything larger than its 0.0001 micron hole size.
To put that into perspective, 1 micron equals around 0.00004 inches, while a human hair is approximately 75 microns wide (source).
The semipermeable membrane captures and retains germs and pollutants in the water while also preventing salt and other minerals from going through. This indicates that reverse osmosis water lacks the minerals found in tap water.
Reverse osmosis can literally save lives in locations where the water contains harmful impurities and is unsuitable to drink. Is it, however, doing more harm than good as a popular health accessory in the Western world?
Next, don’t miss out on our fantastic guide to the best whole-home RO systems on the market.
What minerals does Reverse Osmosis remove?
Because reverse osmosis systems can remove more than 99.9% of all total dissolved solids (TDS) from water, it’s no surprise that beneficial minerals are eliminated during the process.
Our drinking water contains mineral particles such as calcium and magnesium, which we require for strong, healthy bones and teeth, as well as to control blood pressure, muscles, and nerve function. Low quantities of salt, potassium, and phosphorus are also present in tap water and are required for cardiac support, fluid balance, and influencing the growth, repair, and maintenance of cells throughout the body.
Reverse osmosis removes all of these critical minerals.
Where does minerals come from
Humans do not obtain the bulk of their minerals from the water they drink; instead, food is the primary source for the vast majority.
With this in mind, does it make a difference if minerals are removed from our drinking water?
Yes, if you trust the World Health Organization (WHO).
The WHO has issued a paper outlining its concerns about the hazards of reverse osmosis water and why it is a problem.
According to study, drinking demineralized water, such as that obtained by reverse osmosis, will actually take minerals from the food we consume. This is then excreted from the body via urination, limiting the quantity accessible for absorption.
When demineralized water is used for cooking, such as boiling vegetables, the same process occurs. To compensate for the lack of important minerals, they are leached out of the vegetables and into the water.
Demineralized water removes a significant number of minerals, up to 60-70 percent of the total available. This leaves relatively little available for the body, which is one of the reasons why the WHO has said that reverse osmosis water “has a definite deleterious effect on the animal and human organism.”
The minerals that go missing
Reverse osmosis has its origins in military applications, when it was employed to establish a drinkable water source in the presence of contamination. From this crucial application arose a more commercial one, with homeowners utilizing reverse osmosis devices to produce purer water.
Minerals collected from water include the following:
Calcium is the most abundant mineral in the body, accounting for around 2% of total body weight.
Calcium is found in teeth and bones, but it also plays an important role in many of the body’s processes, including as vascular and muscular contraction, blood clotting, enzyme and hormone control, and message transmission between nerves and the brain.
Because calcium is involved in practically every activity in the human body, a deficiency can have catastrophic consequences. A calcium deficit can produce convulsions and potentially fatal heart rhythms as well as weakened bones, which can lead to fractures and osteoporosis.
Magnesium is another essential mineral for good health and well-being. It is vital in the development of healthy bones and is involved in over 300 metabolic events.
A typical human body has about 25g of magnesium, 60 percent of which is contained in bones and the rest predominantly in soft tissues.
Magnesium levels in the body are difficult to assess because the majority of it is found in the bones. A deficiency, on the other hand, might have serious consequences such as weakness, nausea, and weariness.
Continued insufficiency could result in numbness, cramping, convulsions, personality changes, and cardiac rhythm disruption.
Although calcium and magnesium are the most common minerals extracted by reverse osmosis, several other minerals are also filtered out.
Fluoride, copper, chromium, manganese, selenium, iron, zinc, and molybdenum iodine are examples of trace minerals.
The advantages of including minerals in Reverse Osmosis water
The following advantages come from remineralizing reverse osmosis water:
Gives water flavor
Many individuals find reverse osmosis to have a “flat” and disagreeable flavor. However, alkaline water with re-added minerals tastes much better, so you’re more likely to go for a glass of water instead of juice or soda.
Hydration is encouraged
If you believe that drinking demineralized water will make you less inclined to stay hydrated because you dislike the flavor, think again. There are clear health benefits to remineralization. Because of the lower pH level, RO water tastes flat and dull. If you remineralize your water, it will have a higher pH level and you will be more likely to drink it.
Vital to human health
As I previously stated, humans do not rely on trace minerals in our drinking water to exist. Tap water, on the other hand, can provide up to 20% of our daily suggested requirements for minerals such as calcium and magnesium. Consider a remineralization filter if drinking remineralized water would provide you with the piece of mind you require.
Is this the end of reverse osmosis water?
Is it safe to drink filtered water if minerals play such a vital part in the body and reverse osmosis removes these elements?
No, it is not required.
Although minerals in water are good to health, avoiding pollutants, bacteria, and contaminants is also very useful.
The solution is not to avoid reverse osmosis, but to supplement the water with minerals. This entails remineralizing RO water so that you can enjoy the benefits of contaminant-free water while also getting the critical minerals your body need.
If you’re wondering how to remineralize water, there are a few choices to explore. Reverse osmosis remineralization is not as complicated as it may appear, but you will need to obtain appropriate supplies first.
Continue reading to learn how to make alkaline water with Himalayan salt. Following are some options for adding minerals to water.
How to remineralize RO water
1. Pink Himalayan Salt
Himalayan salt is an excellent, simple, and cost-effective way to remineralize your reverse osmosis water. Simply add Himalayan or rock salt to each gallon of filtered water to restore the minerals.
Make sure you don’t use ordinary salt because it won’t work.
Himalayan sea salt includes all 84 trace minerals but is quite inexpensive to purchase. If you get fine salt, you won’t have to worry about a salty flavor in your water.
You can either add a tiny pinch to each glass of water or a quarter-teaspoon to each gallon of water.
Himalayan salt will not alter the flavor of water, but its mineral content will restore all of the minerals in the water.
Using this method not only helps you remineralize water, but it also offers additional advantages, such as:
- Relief from sinusitis
- Loss of weight
- Reduces high blood pressure
- Improved respiratory functions
2. Water mineral drops
Electrolyte blends (also known as trace mineral drops) are mineral compositions found in most supermarkets that include copper, selenium, iron, manganese, calcium, and magnesium. Simply mix the blends back into the water once it has passed through the RO filter.
This is also a very simple option because you just need a few drops in your water container.
If you and your family drink directly from the reverse osmosis faucet, you’ll need to remember to add a drop every time to remineralize.
Alternatively, you can start keeping a designated water jug and make it a rule to only drink water from it from now on.
Blends will range in composition from one brand to the next, but they will suffice for any RO water.
If you want to know how to add minerals to water without putting in a lot of effort, this is one of the simplest methods. You may quickly and easily remineralize any amount of water by adding a few mineral drops at any time.
Adding trace minerals in the form of drops is the most cost-effective approach of remineralizing your water. You must know where to hunt for these trace mineral drops, as some are unquestionably superior to others.
A bottle of mineral drops should be able to treat up to 200 liters of water and should cost less than $20.
Look for trace mineral drops from well-known producers who have invested decades of research into their goods, such as the Quinton Wellness drops.
- Remineralization on the go
- Enhances electrolyte balance
- Aids in the restoration of natural rehydration and equilibrium

4. Buy and RO system with remineralization
If you add an extra filter to your system, you can remineralize reverse osmosis water at the source.
Most models can be upgraded with a pH-balancing or remineralization filter without having to replace the entire system.
Some minerals are put back into the water after it has been filtered; the amount depends on a variety of parameters such as flow rate, water temperature, and the water’s current pH level.
Although there is evidence that this can dramatically increase the pH of the water, the quantity of remineralization can vary greatly.
Allowing the reverse osmosis system to remineralize the water is the simplest approach to remineralize it.
RO systems are comprised of five stages: three pre-filters, a RO membrane, and a post-filter.
Some premium RO systems include an additional stage that includes a mineral filter. The filter returns little amounts of healthful minerals to the water as it goes through.
The majority of RO systems with a remineralization filter simply return calcium. Others include calcium and magnesium, while others can have up to five beneficial minerals.
The mineral filter ensures that you are drinking delicious, healthy mineral water.
On the flipside, a RO system with a remineralization filter will cost a little more.
Furthermore, the filter may not meet all of your mineral requirements. If the filter just provides calcium, you may still need to add other critical minerals using one of the techniques described below.
Remember to replace the mineral filter after the manufacturer’s specified time frame (3-6 months for some systems, 6-12 months for others)

5. Add a remineralizing filter to your existing RO system
Don’t worry if you already purchased a RO system without a mineral filter; you may still add one.
Many RO systems include a remineralization filter as an option, but if yours does not, you can purchase a filter intended for easy installation at your main waterline, right after your reverse osmosis unit. The advantage of a remineralization filter is that it creates alkaline water from your own faucet, eliminating the need to add mineral drops as an afterthought.
The majority of remineralizing filters will add calcium to RO water. Some may additionally remineralize water with magnesium, and some go even farther, adding up to five different types of minerals back into your RO water.
The majority of remineralizing filters will add calcium to RO water. Some may additionally remineralize water with magnesium, and some go even farther, adding up to five different types of minerals back into your RO water.
Here’s an APEC mineral filter for APEC RO systems, an Express Water RO system mineral filter, and an iSpring RO system mineral filter. It’s worth noting that the most of these mineral filters are compatible with any typical under-sink RO system that uses 10″ inline filters. However, before you order, double-check the size of the fittings.

6. Add an alkalization stage to your RO system
If your filter does not have that stage, it is simple to add. This stage resembles a filter attachment that contains all of the valuable minerals. You may also find reviews of some of the top RO Systems here.
When the water is filtered, it travels through this alkaline filter, which replenishes the minerals in it. The minerals in the water will dissolve as it goes through this filter, providing you with a healthy drinking experience.
It is advised by a reverse osmosis system that includes an alkalization stage.
7. Make use of an alkaline pitcher
If you want to boost the pH level and bring minerals back in, you can also use a simple pitcher.
There are various alkaline pitchers on the market that provide a simple method for remineralizing RO water.
Alkaline water pitchers are another inexpensive alternative for adding minerals like calcium and magnesium to water.
A filter cartridge in an alkaline water pitcher adds a measured amount of minerals back into a batch of water. Because it is a pitcher, you will not receive quick remineralized water; instead, you will need to feed reverse osmosis water from your tap to the pitcher and wait a few minutes for filtration. Water alkaline pitchers, on the other hand, are more reasonably priced, ranging from $20 to $40 per pitcher.
The fact that alkaline water filters do not need to be placed at your water line is an obvious advantage. Alkaline filters are a wonderful alternative for remineralizing your water with a filter that does not demand extra work (and may even violate the requirements of your rental contract).
These pitchers adjust the pH of the reverse osmosis water while also remineralizing it. Some designs include built-in clocks that count down to the next filter change, which is a convenient feature.

8. Alkaline water bottles
An alkaline water bottle is an excellent solution for on-the-go access to remineralized reverse osmosis water.
Again, there is nothing to set up if you prefer to remineralize your water with an alkaline water bottle. Fill your bottle with RO water and carry it to work with you (or simply to another room in your house). The bottle features a filter that will raise the pH of the water while also adding minerals like calcium and magnesium to improve its taste.
You’d think that these water bottles are on the ugly side of utilitarian, but they’re actually rather beautiful to look at overall.
Alkaline water bottles are often priced comparable to pitchers, ranging from $30 to $50 for a single bottle and filter. Filters should be replaced every 6 weeks, though this varies depending on the manufacturer and the concentration of minerals added to your water.
Following the WHO report, reverse osmosis water has come under scrutiny, yet the truth remains that it is a valuable technique to obtain pure water that is free of chemicals and toxins.
These types of filters provide confidence to folks who are concerned about pharmaceutical residues reaching the water supply. However, the current issue regarding a lack of minerals should not be overlooked.
Because there are major health benefits to avoiding unintended absorption of pollutants and chemicals, reverse osmosis water is still a viable alternative. It is possible to have the best of both worlds by re-mineralizing the water, enjoying the important protection of the filter while also gaining access to the health advantages of minerals.
Once you know what to do, remineralizing reverse osmosis water is quite simple. The key is to make sure you only buy high-quality items to replenish the minerals you’ve lost; don’t be lured by low-quality products on sale at the dollar shop.
Stick to high-quality Himalayan sea salt or correct electrolyte and mineral drops, or invest in a respected manufacturer’s filter or pitcher. By doing so, you can continue to enjoy wonderful clean water with every conceivable health advantage.
Can you Remineralize reverse osmosis water?
You may quickly and easily remineralize any amount of water by adding a few mineral drops at any time. A bottle of mineral drops should be able to treat up to 200 liters of water and should cost less than $20. If you add an extra filter to your system, you can remineralize reverse osmosis water at the source.
How do RO systems remove minerals?
The reverse osmosis membrane, also known as the semi-permeable membrane, is what gives a RO system its name. While a standard filtered water solution will not have holes small enough to remove minerals from your drinking water, RO membranes feature tiny pores of around 0.0001 microns that can trap even the smallest impurities – including minerals.
How can these membranes avoid becoming blocked so quickly? Because there are many filter stages before water reaches the RO membrane – often a pre-filter and an activated carbon filter with a higher micron rating that is meant to remove bigger particles that could quickly clog the membrane’s pores. Furthermore, due to the high-pressure operation of a reverse osmosis system, contaminants such as minerals are likely to bounce back after striking the membrane, and they will be drained away along with some wastewater in the RO chamber.
If I’m adding minerals to RO water, why should I bother with reverse osmosis at all?
That’s a good question, and the answer is that it depends on the level of filtered water you’re looking for. For example, if you only want to remove chlorine and lead from your water, a carbon filter cartridge alone may suffice – and it won’t remove those valuable minerals, saving you the work of remineralization. If, on the other hand, you insist on removing the widest possible range of impurities from water, only a RO system may be able to deliver. If you still wish to profit from these minerals, you’ll need to remineralize RO water.
How else can I drink my minerals?
If you don’t want to go to the trouble of remineralizing your RO water, there are lots of other ways to receive some of your daily mineral requirements from your beverages. For a morning pick-me-up, try mixing mineral-rich green powder or green blends into your filtered water. You don’t need to add the powder to every glass of water you drink; one serving per day should suffice.
You may also construct a juice or smoothie using fruits and vegetables that are naturally high in beneficial minerals to drink in the morning or evening. You’ll get a lot more minerals than if you drank remineralized RO water.
