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 reverse osmosis.

According to the World Health Organization (WHO), Calcium and Magnesium are essential 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 risk 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 remineralizing RO (Reverse Osmosis) water

These are the benefits of reverse osmosis water remineralization:

1. Gives pure water an appealing flavor

People find reverse osmosis to taste flat and distasteful. However, alkaline water with reconstituted minerals tastes more pleasant, 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 drinking demineralized water makes it harder to stay hydrated.

Reverse Osmosis water has a lower pH level, making it taste dull 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 the security and peace of mind that comes with drinking remineralized water.

Why Are Minerals Important?

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

Let’s overview the water minerals andwhy we each need them.


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

While calcium is an essential 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, and long-term effects such as seizures, muscle cramps, numbness, heart disorders, and even death.

Trace Minerals

Water contains trace minerals such as potassium, sodium, phosphorous, 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 correctly. 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 to add calcium back to the 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 the recommended period (three-six months for some systems and 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 advanced water filtration technology can be installed right after your reverse osmosis system. 

Remineralization filters work to produce filtered water supply 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. 

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

4. Trace Mineral Drops

Adding trace minerals in drops is the cheapest way to remineralize RO water without filters. It is essential 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 your chosen product, 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.

Depending on the brand, a single order of mineral water drop can cost between $20 and $40.

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 and food and avoids 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 filter pitcher in your home.

It is wise to make alkaline water at an affordable price rather than spending more. And also an excellent option for long-term usage.

PUR water pitcher

You can choose one which removes the maximum contaminants and heavy metals according to your need.

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

  • The pH level should be between 8.0 and 10.0
  • Types of mineral salts added (calcium, magnesium, and potassium).
  • NSF certification
  • Remove harmful contaminants from water
  • Filter cartridges and housings have a shelf life of approximately 5 years.
  • Filter cost

6. Use the green blend to remineralize RO water

Extracts from vegetables and plants to increase the regular water mineral content and provide nutrients are 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 for drinking 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 using Reverse Osmosis water in your aquarium. RO filter can produce purified soft water increases until it’s minerals-free.

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

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 kHz
  • General Hardness – 10GH

Best Remineralization Strategies

This simple recipe is great for achieving the desired water conditions 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 starting the osmosis remineralization process. 

Give the tank a spin with regular 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 semipermeable 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, including calcium, magnesium, and potassium.

This is an excellent way to remineralize RO water with natural 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 risks.

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 adding Himalayan salt to your water, go ahead! You can easily find this salt online.

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

This is a prominent 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 pretty beautiful to look at.

Alkaline filter 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 of drinking demineralized waters.

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

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