How To Remineralize Water After Reverse Osmosis

by Dr. Jonathan Doyle - Updated May 26, 2021
Reverse osmosis is considered to be the most advanced water filtration technology available on the market today. The precise 0.0001 micron filtration can remove almost all contaminants in water, providing filtered water made up of only water molecules. A reverse osmosis water filter is the most effective way to purify your water. In some regions with worrying water quality, an RO system can be a life-saver. Check here to learn about the best RO systems.

Is it really healthy to drink demineralized water?

Some of you may be wondering if it's really healthy to drink pure water. We've been told that mineral water is beneficial to health. Some authority agencies and professors have clarified that food is the main source of mineral supplements, rather than water, so demineralized water should be fine.
However, WHO released a report that describes some risks and adverse effects from pure RO water. Drinking only demineralized water in the long term can have deleterious effects on the intestinal mucous membrane, the metabolism, and the mineral homeostasis of the body, leading to problems with a variety of bodily functions. Severe acute damage, such as hyponatremic shock or delirium, can occur if intense physical effort is followed by the ingestion of several litres of low-mineral water. This symptom is called “water intoxication.”
Many of us believe that our healthy diet provides sufficient micronutrients. However, cooking with low-mineral water was found to cause substantial losses of all essential elements from food. Additionally, the modern diet that many people follow may not be an adequate source of minerals. So don’t ignore any action that may cause the loss of these essential elements, because it could be detrimental. Even the low intake of minerals from drinking water could be of vital importance.

Benefits of drinking remineralized water

While water treated with reverse osmosis is free of any toxic elements, it's also missing some minerals that are essential for good health. Remineralizing your RO water allows you to regain those micronutrients while ensuring that your water is free of contaminants. The major micronutrients contained in mineral water are calcium, magnesium and trace minerals. Calcium is a substantial component of bones and teeth, and magnesium plays an important role as a co-factor and activator of more than 300 enzymatic reactions. Sodium and potassium help muscles to contract and nerves to function correctly. Insufficient quantities of these substances leads to poor physical function.
Furthermore, mineral water quenches thirst effectively. Water that contains electrolytes helps you quench your thirst faster than drinking pure water. RO water also tastes flat and boring because it has a neutral pH level. Remineralized water will automatically taste better because it becomes the perfect blend of quality and purification. This water is perfect for making tea or coffee and for cooking. You will also be more inclined to drink water with a better taste, which will increase your water intake, keeping you properly hydrated.

Treatment techniques to remineralize your water

Though demineralized water lacks necessary micro elements, it doesn’t mean that we should stop drinking RO water. It’s the best way to remove harmful contaminants from your drinking water, especially bacteria, viruses, and heavy metals. Check here to learn more about what kind of contaminants that RO systems can remove. As long as you are eating a balanced diet, and ensuring that you replenish your elecrolytes after exercise, you'll be fine. For those who aren't able to supplement their micronutrients through their diet, though, there are several ways to improve your RO drinking water.
Effective RO Membrane

Buy an RO system with a remineralize water filter

This is the easiest way to enjoy the benefits of reverse osmosis and mineralized water. A typical RO water filter system consists of at least 3 filtration stages—a PP filter, an activated carbon filter and the RO membrane. Some with more filtration stages will add a post-activated carbon filter or a remineralize water filter. When water passes through the post mineral filter, the filter will add minerals back into the water to balance the pH level.

Add an additional remineralize water filter

If you already have an RO system, you can buy a separate remineralize water filter. With this filter, you don’t need to buy another RO water filter system with a mineral filter built in. This Waterdrop remineralization is designed to be compatible with 1/4” quick connect tubing. It can connect with most reverse osmosis water systems or undersink water filtration systems on the market. It includes 18 natural materials to restore minerals like calcium, magnesium, sodium, potassium, etc. Drinking this kind of remineralized water will, in the long run, help prevent chronic diseases, slow down the aging process, and improve digestion and immunity.

Add mineral salt

Another option is to add a little mineral salt in your drinking water. Natural salt, such as Himalayan salt, instead of common table salt, contains all the necessary trace minerals that are removed during the reverse osmosis process. This is one of the most cost-effective means of remineralizing water.

Conclusion

It is essential to drink water that contains an adequate amount of minerals to maintain good health, and it tastes better too. However, it’s not suggested that you abandon your RO water filtration system. There are many other ways to remineralize RO water, ensuring that you're always able to drink and cook with clean, safe and beneficial water.
