How to Remineralize RO Water

You may have come across the term reverse osmosis, but do you really know what occurs or the end result of it all?

In a RO filtration system, you will find a membrane and unique filters that work to catch water before it pours out. It involves the most basic filtrations system, and on a microscopic level.

More so, the RO membrane lets water pass through and flow into the glass while leaving behind any particle that has a size larger than the 0.0001-micron pore size.

To help you get a better perspective of the process, one micron equals an average of 0.000004 inches, and human hair averages at 80 microns. 

Usually, the filter also features a semipermeable membrane, which helps to catch water, bacteria, and impurities in water. Moreover, it also works to prevent salt and other minerals from penetrating through the filter. Thus, reverse osmosis water does contain minerals that you would typically consume.

In areas that have dangerous contaminants, which are unsafe to consume, reverse osmosis can be highly convenient. That said, a modern health accessory today, the water is doing more harm than good for its users.

The Source of Minerals

the source of minerals

People won’t necessarily get the most from the water they consume. For most people, food is the primary source of minerals. 

Keeping this in mind, does it matter if we remove any minerals from drinking water?

If you believe information from The World Health Organization, then it’s correct, yes. According to recent reports by WHO, there are many side effects associated with reverse osmosis of water, and the reasons it can cause a problem.

The report by WHO states that consuming demineralized water that undergoes reverse osmosis, will compromise the quality of minerals in your food. The minerals may come out as urine out the body, and this may reduce the amount available for absorption significantly. 

The same procedure occurs when you use demineralized water for cooking procedures, such as when boiling vegetables. The fundamental minerals leach out from the food, and directly into the water to compensate for the mineral absence. 

The amounts of minerals that leach out due to demineralized water are significant, and this can reach as high as 75%. This leaves a small amount of the body and is one of the main reasons why WHO states that reverse osmosis has adverse effects on the body.

The Minerals That Go Missing

Reverse osmosis has its origins in military usage, where it was commonly used to produce safe water for drinking. From this critical use, a commercial one came, and more households have adopted the RO technique to purify water. That said, these are some of the minerals which are compromised by the process:


Calcium is among some of the most common minerals on the body today. It makes up well over 2% of the weight of your body. Aside from being present in the bones and teeth, it also plays a significant role in your body functions. These include functions such as muscular contraction, blood clotting, regulation of enzymes, and more.

Since calcium involves every process in the body, any shortage can easily lead to adverse side effects. More so, it may also lead to weaker bones, which makes the body prone to issues such as osteoporosis, calcium deficiency, and more.


Magnesium is also another vital mineral for your health and wellbeing. It plays a significant role in well over 300 biochemical reactions, and also in the development of bones in the body.

More so, the typical human body contains an average of 30g of magnesium, with 60% of the minerals existing in the bones. The remaining amount exists in the soft tissues of the body. 

The levels of magnesium in the body are also challenging to measure since most of it exists in the bones. That said, a deficiency could lead to profound side effects, including nausea, fatigue, and more.

Any continued deficiency could lead to issues such as cramps, seizures, mental complications, and disruptions in the heart rhythms.

Trace Minerals

While magnesium and calcium are the main minerals that are compromised during reverse osmosis, various other minerals are also filtered out. These include minerals such as copper, fluoride, manganese, zinc, and more.

Does This Spell the End for The Use of RO Water?

Since minerals play a significant role in the body, and RO stripping away these elements, this does not mean that you should avoid filtered water.

Not necessarily! Even if minerals are crucial for your health, avoiding harmful dirt, bacteria, and chemicals are also vital. The solution, in this case, is not to avoid water made using reverse osmosis, but instead add minerals to the water. Thus, re-mineralizing RO water can be an excellent way for you to restore the quality of the water. 

If you are wondering how exactly you can remineralize RO water, there are few options you should consider.

First, reverse osmosis remineralization is not as difficult as it seems, and you may have to invest in unique supplies. If you want to know how to prepare alkaline water by using Himalayan salt, then this guide is perfect for your needs.

How to Remineralize RO Water

Most of the modern RO systems for homes today feature inbuilt remineralization filters. These help to reintroduce the healthy minerals during the final stages before pouring out the water. That said, there are few other techniques you can use for this process.

Add a Mineral-rich Salt.

Quite contrary to what you may think, this process does not entail adding table salt to your water. On the contrary, it involves pouring it into your system and using a unique type of sea salt, which has many minerals. The best to apply for this process would be Himalayan Salt. Himalayan sea salt contains various kinds of trace elements, and it’s also readily available. Ensure you go for the fine salt, such that you don’t have any saltwater, which has a bad taste.

Alter the RO Water pH level With a Filter

You can perform the remineralization process of RO water at the source by installing an additional filter to your system. 

Usually, it’s easy to set up without having to adjust the entire water filtration system, which can be challenging. 

Once you filter the water, the filter will add some minerals back to the water. The amount depends on various factors, including the flow rate, the temperature of the water, and the pH of the water.

While there is evidence that this process will increase the pH of water, the quality of remineralization usually varies significantly.

Use an Alkaline Pitcher

Plus, you can also use a pitcher if you want to raise the pH level, and add minerals back to the water. There are several alkaline pitchers on the market that provide a convenient way for you to remineralize RO water. 

You can use these pitches to adjust the pH and also to re-mineralize the osmosis water. Some types even feature inbuilt clocks that indicate when you have to perform the next filter change.

RO Water – Is it For the Future?

Based on the report from WHO, reverse osmosis water has come under scrutiny over the years. That said, the fact still remains the same – and that is, it helps remove contaminants.

These types of filters are perfect for those who are worried about contaminants that may compromise water supplies. That said, we also have to consider the high levels of mineral wastage that also occurs along with such resources.

There are various health benefits associated with its use, including the removal of contaminants, which have been associated with countless health issues. Thus, by remineralizing the water, you can still enjoy RO water while maintaining optimal mineral levels. 

It’s easy to remineralize your water once you have insight into the specific steps involved in the process. The main factor to consider is that you should go for quality products, to help replace the lost minerals. Never be tempted by inferior quality products, as they are likely to be highly inconveniencing.

Also, remember to use high-quality Himalayan salt, or the correct electrolyte and mineral drops. Plus, you can also buy a filter or pitcher, which is produced by a reliable company. Through this approach, you will easily enjoy drinking high-quality water when you need it the most.
