Reverse osmosis systems are an excellent drinking water filtration process. They remove all harmful contaminants from water such as chlorine, fluoride, heavy metals, sediments, organic matter, and other toxic chemicals. However, reverse osmosis technology is so efficient that it eliminates all of the beneficial components of water. And the final result of reverse osmosis water is nearly distilled water, with many of the natural salts and minerals found in water extracted.

However, you can still remineralize the filtered water using various methods. So, if you’re wondering how to add minerals to RO water, look no further than this article. Continue reading to learn more about it.

What is Reverse Osmosis?

What is Reverse Osmosis

Reverse osmosis (RO) is a water purification process that demineralizes water by passing water through a semipermeable Reverse Osmosis Membrane. Water flows from the more concentrated side of the RO membrane to the less concentrated side to provide safe drinking water.

RO membranes are typically made up of a non-porous polymeric film that is supported by porous layers. The openings in this polymeric film are small, allowing RO to extract most dissolved salts, organics, bacteria, or pyrogens.

Reverse Osmosis Water Benefits

Water purified through reverse osmosis contains fewer pollutants and salts, no pathogens or bacteria, and is completely safe for terminally ill patients. It removes contaminants via a membrane filter that prevents solids and prominent microbes from passing through as long as the membrane filter is replaced regularly.

Reverse osmosis water removes harmful molecules from the body. Calcium deposits, for example, can harden the water and have a negative impact on your skin. Furthermore, reverse osmosis removes 90 to 95 percent of sodium from drinking water. RO removes sodium via the same thin membranes that remove contaminants.

What Minerals Does Reverse Osmosis Remove?

RO purification technology can eliminate these unwanted minerals and other harmful heavy metals and chemicals such as lead, arsenic, and aluminum from your drinking water. It removes 92-99 percent of the essential calcium and magnesium. Magnesium helps in the regulation of blood glucose/sugar levels as well as nerve function. Calcium, on the other hand, strengthens bones and helps control heartbeat rhythm.

It also eliminates trace minerals, also known as microminerals. Trace elements are mainly used as catalysts in enzyme systems. Minerals such as zinc, iron, iodine, copper, fluoride, selenium, chromium, and others are removed by reverse osmosis.

Benefits Of Adding Minerals To Water After RO 

Larger particles in the water are filtered out during the Reverse Osmosis process, leaving only pure water molecules to pass through your water tap. While this process has many advantages, the filter is so effective that it eliminates valuable minerals such as calcium, potassium, and magnesium. The purified water may become demineralized as a result of this. And hence, the water needs to be mineralized before drinking.

There are numerous advantages to remineralizing RO water, including enhanced taste and increased pH to healthy levels. While most of the minerals required by the body are obtained from food and dietary supplements, minerals found in water are also important for health. Remineralizing RO water can help bridge the gap between what we can get from food and the recommended intake levels.

How To Remineralize RO Water

The simplest way to enjoy the benefits of mineralized water from an RO is to buy a RO system with a water mineralizer filter. Alternatively, adding a remineralized water filter can produce satisfactory results. Another option is to supplement your drinking water with mineral salt. Instead of common table salt, natural salt, such as Himalayan salt, contains all of the trace minerals that are removed during the reverse osmosis process. Let us now proceed to inform you about the methods to remineralize RO water.

1. Buy an RO system

This is the simplest and most convenient way to reap the benefits of reverse osmosis and mineralized water. Basic RO systems have five stages: three pre-filters, a RO membrane, and a post-filter. At the same time, some high-end RO systems include an additional stage that consists of a mineral filter. These RO systems will include a post-activated carbon filter or a water remineralization filter. As water flows through the post-mineral filter, minerals are added back into the water to balance the pH.

2. Add Remin Filter to your RO System/ Remineralize water filter

If you’re wondering how to add minerals to RO water or your existing RO system, this method is for you. Simply install a remin filter after your reverse osmosis unit in your main water line. It is essentially a mineral-containing filter-like attachment. Minerals are dissolved back into the water as the water passes over them.

3. Add mineral salt 

You can add minerals to RO water by simply adding some natural salt to the RO system, like Himalayan salt or rock salt. Just a pinch will suffice. It does not affect the taste of water. Himalayan sea salt has 84 trace minerals, which are extremely beneficial to our health.

However, it is not recommended to use table salt because it may contain too much sodium, which can cause other problems.

4. Add Trace Mineral Drops

If you want to know how to add minerals to RO water without putting in a lot of effort, this is one of the simplest methods. Minerals can be added to RO water at any time by simply adding a few mineral drops. Trace mineral drops, also known as electrolyte blends, contain mineral concentrates. These mineral drops contain copper, selenium, iron, manganese, calcium, and magnesium as constituents. After the RO filter, simply mix the blends back into the water.

5. Use Alkaline Water Pitcher

If you want to increase the pH level and add minerals to RO water, you can use a simple alkaline pitcher. A small remineralization stage is located at the top of the alkaline water filter pitcher. As it drips from the top into the bottom chamber, it replenishes the water with trace amounts of minerals.

6. Green Blends

If you enjoy minerals derived from plants, this is another excellent option for remineralizing reverse osmosis water. Greens blends are made up of minerals extracted from vegetables and plants. It is a very diverse set of balanced minerals that are extremely beneficial to your health. The disadvantage is that it alters the taste of the water. They are also not a good long-term solution.


RO systems can provide the safest drinking water. But the demineralization of water can be cynical. However, once you know what to do, remineralizing reverse osmosis water is pretty simple. There are numerous additional advantages, and the ability to remineralize the filtered RO water makes them an ideal option for any household.


The main distinction between these two types of water is the source from which the water is obtained in the first place. Organic water, pure H2O, or pure mineral water are examples of this type of water. It naturally contains minerals that are beneficial to health.

 The only requirement is that it be filtered through hard strains, such as stones of varying sizes or sand, to eliminate unnecessary contaminants. On the other hand, RO water can be obtained from any source because it is treated with reverse osmosis technology before being consumed. The RO method merely employs pressure to purify water.

A well-balanced diet usually contains all of the necessary minerals. However, some minerals absorbed from water are better than minerals absorbed from food. Calcium, magnesium, iron, potassium, zinc, sodium, and other minerals necessary for health should be present in water.

Magnesium is necessary for the regulation of blood pressure, blood glucose levels, and nerve function. Calcium is required for the formation and maintenance of strong bones. As a result, these minerals are essential in our daily drinking water.

Salt, manganese, iron, fluoride, lead, and calcium are generally removed by reverse osmosis. However, it also eliminates more than 90% of all impurities, including minerals, from the drinking water supply, demineralizing the water. The direct water that emerges from the filtration process lacks sufficient minerals. As a result, it is critical to mineralize the water before drinking it.

Consuming water with low mineral content, i.e., water with low TDS disrupts our body’s homeostasis. Increased excretion of essential minerals such as sodium, calcium, chloride, and potassium ions disrupts the blood’s delicate osmotic pressure and causes an electrolyte imbalance. 

Consuming RO demineralized water under these conditions further deprives the body of necessary nutrition. It eventually causes distressing symptoms such as headaches, fatigue, weakness, muscular muscle pain, an irregular heartbeat, and a negative effect on hormone secretion, kidney functions, and bone mass.

When you add trace mineral drops to your water, you’ll think you’re drinking mineral-rich water from a sought-after natural source. A mineral-rich unprocessed salt, such as Himalayan salt, contains 84 trace minerals, and can be added to mineralize the water.

Other methods include alkaline pitchers, which filter water while raising the pH and reintroducing calcium, magnesium, and other beneficial minerals. You can also use green blends in your water naturally derived from plants and high in trace minerals and macro minerals.

RO water is said to be dead water because it eliminates all minerals – both good and bad. As a result, it produces neither harmful nor beneficial water. However, reverse osmosis filtration systems do more than just remove contaminants; they also add minerals. 

RO systems/appliances that remineralize RO water, compensating for trace minerals lost during the RO process. As a result, RO is no longer dead water devoid of beneficial minerals such as calcium and magnesium. It is no longer dangerous to health.
