9 Ways to Remineralize RO Water

Some people prefer a high pH level, so they remineralize RO water.

Essential minerals, such as magnesium and calcium, can be eliminated during the process.

According to the World Health Organization (WHO), Calcium and Magnesium are important for human health.

Many people don’t know they can remineralize the water.

It is easy if you are familiar with the different methods. This begs the question: Why and how to remineralize RO water that has been purified already?

Is it a good idea to continue drinking water? Do you need to remineralize water before you drink it? 

This article will take a closer look into reverse osmosis water.


The effects of drinking demineralized waters are still being researched. Mineral-free RO water is safe and won’t cause you to have any deficiencies. 

Experts agree that you should consume all the essential minerals as long as you eat a healthy diet.

Drinking demineralized water can pose a risk to some people with certain medical conditions. 

It’s a good idea to speak to your doctor if you have any questions about demineralized water or adding minerals to the water.

There are various ways to get alkaline water, one of the best and most affordable is water pitchers.

Benefits of remineralize RO (Reverse Osmosis) water

These are the benefits of reverse osmosis water remineralization:

1. Gives pure water an appealing flavor

People find reverse osmosis taste flat and unappetizing. However, alkaline water with reconstituted minerals is more pleasant to taste, so you are more likely to drink water than soda or juice.

2. Encourage Hydration

Remineralization is a good option for your health if you believe that drinking demineralized water will make it harder to stay hydrated.

Reverse Osmosis water has a lower pH level, which makes it taste boring and flat. You can make your soft water more appealing by remineralizing it.

It will increase the pH level and the desire to drink it.

3. Important for Human Health

I have already mentioned that we do not rely on trace minerals in our water for survival. 

However, we can achieve up to 20% Below are the daily recommended intakes of beneficial minerals such as calcium and magnesium from tap water. 

Consider a remineralization filter if you want to have the security and peace of mind that comes with drinking remineralized water.

Why Are Minerals Important?

The minerals are essential for our bodies and seem a bit crazy to think that our bodies need minerals – i.e. the organic substances found within rocks and soil

Let’s take an overview of the water minerals and why we each need them.


Calcium carbonate is the most important mineral content in the human body and can be found in all parts, including bones and teeth.

While calcium is an important mineral for teeth and bones, many people only realize that it is also required for nearly every other process in the body. 

Calcium deficiency can lead to brittle bones, convulsions, and even heart disease.


Magnesium can stimulate and control hundreds of biochemical reactions. It can also help develop and maintain healthy bones.

A deficiency in this mineral could lead to various health problems including nausea, fatigue, weakness, long-term effects such as seizures, muscle cramps, numbness, heart disorders, and even death.

Trace Minerals

Water contains trace minerals such as potassium, sodium, and phosphorous, in addition to calcium and magnesium.

The human body requires a small amount of sodium (table salt), for nerve impulse regulation and muscle contraction

Sodium and potassium help to contract the muscles and allow the nerves to work properly. Potassium also regulates the heartbeat.

How to Remineralize RO Water

1.  RO System with Mineral Filter

Reverse osmosis water can be remineralized, so let the system do it.

The basic RO system has five stages to maintain total dissolved solids (TDS) and is also perfect for your brown well hard water.

Premium RO filter includes an additional stage of the mineral filter.

The filter returns small amounts of healthy minerals to the water as it passes through.

The Reverse Osmosis system has a remineralizing water filter that adds calcium back to its system. 

Some RO systems add calcium and magnesium, while others add up to five healthy minerals.

Mineral filters ensure mineral water.

An RO system that includes a remineralization filter will cost you a little more.

The filter might not be able to meet all of your mineral intake requirements. 

If the filter adds only calcium, you might still need to use one of these methods to add essential minerals.

Note: Replace the mineral filter under recommended period (three-six months for some systems, six-twelve months for others).

2. Addition of Mineral/Electrolyte Blends

Electrolyte Blends contain extracts of beneficial minerals such as sodium, magnesium, and potassium. 

They are easy to use and can be found in many forms and flavors. For example, you can drop them in a glass of water and mix them instantly. 

The composition of the blends varies depending on which brand. 

These soluble minerals provide balanced alkaline water benefits and boost the immune system.

3. Remineralizing Filters

A fantastic way to get rid of rust is to use remineralizing filters. It’s easy to add minerals back to the water by using an under-sink reverse osmosis system.

This water filter can be installed right after your reverse osmosis system. 

Remineralization filters work to produce filtered water from your faucet. It means you don’t need to worry about adding mineral drops.

Many filter types can remineralize RO water with calcium. Others may also remineralize with magnesium.

Some filters can even add up to five kinds of minerals back to your Reverse Osmosis water.

The average cost of a remineralization post-filter cartridge is around $80. After 6 months, the filter will need to be replaced. 

An RO system that includes a remineralization filter of the drinking water will cost you more. 

An RO system that includes remineralization of the drinking water filter will cost you more. 

You should ensure that you are purchasing an independent filter. It must come with its housing and connections and not be used in a separate filter system.

4. Trace Mineral Drops

The addition of trace minerals in drops is the cheapest way to get remineralized RO water without filters

It is important to know where to find trace mineral drops. Some are better than others.

You should look for trace mineral drops made by established companies that have invested decades in research, such as Quinton Wellness drops.

Depending on which product you choose, you might need to add mineral drops before you drink. Or you may be able to add minerals to large quantities of water in a pitcher. 

A single order of mineral water drop can cost between $20 and $40 depending on the brand.

They are usually good for several weeks or even months.

I Recommend: Quinton Liquid Mineral Drops

  • Waterdrop remineralization on the move
  • Improves electrolyte balance
  • It is helpful in Natural rehydration and homeostasis.
  • Cellular response time increases
  • Boosts immune response time
  • Enhances brain function & nervous system

5. Use of Alkaline Water Pitchers

Use the Alkaline water pitcher to remineralize RO water for coffee, food, avoiding kidney stones, or daily basic needs.

You can simply store your filtered water in an alkaline water pitcher, and it will bring back all minerals.

However, this method is more expensive than the others to mineralize the water. It is good to have an alkaline pitcher in your home.

It is a smart choice to make alkaline water at an affordable price rather than spending more.  And also a great option for long-term usage.

You can choose one which removes the maximum contaminant according to your need.

Several important characteristics to be aware of when purchasing an alkaline pitcher include:

  • The pH level should be between 8.0 and 10.0
  • Types of minerals added (calcium and magnesium, as well as potassium).
  • NSF certification
  • Any additional contaminant removal
  • Filter cartridges and housings have a shelf life of approximately 5 years.
  • Filter cost

6. Use a green blend to remineralize RO water

The use of extracts from vegetables and plants to increase the water’s mineral content and provide nutrients is known as a green blend. 

It is an effective way of remineralizing RO water naturally at your home.

This treatment is expensive because it is organic and comes from plants and vegetables. 

The aftertaste associated with green powders is another disadvantage. It can take some time for you to adjust to the taste.

Important! They may alter the taste of pure water you don’t like.

There are many options as we have already discussed. Consumers need to know their hard water quality and choose the right option.

7. Remineralize RO water for an aquarium?

You will need to add an extra step if you are using Reverse Osmosis water in your aquarium. RO filter can produce purified soft water until it’s free of minerals.

You will have to reintroduce some compounds to provide many health benefits for your fish.

RO water needs to add some minerals before using it for your pet or dogs.

It helps to maintain optimal living conditions for your aquarium life.

Keep the right conditions

Your fish will thrive best at a pH around 7 – 7.5. These are other water parameters you should consider.

  • Total Dissolved Solids 390 ppm
  • Carbonate Hardness – 8 to 9 kH
  • General Hardness – 10GH

Best Remineralization Strategies

This simple recipe is great for achieving the water conditions you desire in 5 gallons tank of water.

  • 5 mL water conditioner (approximately 1 capful)
  • One teaspoon of baking soda
  • 1/4 teaspoon acid buffer

You will need to thoroughly rinse your tank before you start the remineralization process. 

Give the tank a spin with tap water and let it dry completely before adding Reverse Osmosis water.

Even if you don’t have the necessary chemicals, you can substitute them with other common ingredients. 

To remineralize water for fish tanks, a combination of Epsom salt and calcium chloride works wonders.

We recommend adding remineralizing carts to your tank for a more efficient approach.

These cartridges can be used to re-establish the pH of your tank water after the RO membrane has removed all minerals. 

It is best for aquariums that have higher pH requirements.

8. Pink Himalayan Salt

You might have never considered pink Himalayan salt before. 

Himalayan salt is a natural source of trace minerals, which include calcium, magnesium, and potassium.

This is a great way to remineralize RO water with salt.

You will need to add Himalayan salt to a glass jar. Fill it up to 1/4 full.

Then, add water to make it fill. Leave it for 24 hours. It’s said to have more benefits than just remineralizing drinking water.

It’s also believed to balance the body’s negatively and positively charged ions, which can help improve overall health.

This one might not be for you if you find it too difficult to remember to make a batch of single water. 

If you enjoy the idea of Himalayan salt being added to your water, then go ahead! You can easily find this salt online. 

It is important to adhere to the guidelines as excessive salt could be dangerous.

This is an obvious disclaimer: pink Himalayan Salt is not the same as regular table salt. It has much less sodium than most salt.

  • Sinus problems solved
  • Weight loss
  • Lowers high blood pressure
  • Improved respiratory function

9. Alkaline water bottles

An alkaline water bottle makes it easy to access remineralized RO water on the go.

Again, if you choose to remineralize your filtered water using a water bottle, there is nothing you need to do. 

Fill your RO water bottle and take it to work or another room in the house.

The filter in the bottle will raise the water’s pH and add minerals like calcium and magnesium to enhance its taste

These water bottles might seem unpractical, but they are quite beautiful to look at.

Alkaline water bottles generally cost $30- $50 per bottle. 

Filters should be replaced approximately every 6 weeks depending on how many minerals are added to the water.

Final Thoughts

As I said, experts aren’t sure of the long-term effects that drinking demineralized waters will have.

You can drink Reverse Osmosis water as long as your diet is healthy and you don’t have any major health conditions.

However, it is a good idea to be cautious and use one of these methods to remineralize RO water.
