The Reverse Osmosis (RO) is a process of purifying water wherein it removes the contaminants present in the water. However, RO is non-selective as it also removes the good stuff present in the water such as the minerals magnesium and calcium. This article is not meant to debate whether remineralized water is best for drinking or not, but is meant to provide information that this option is available.
Advantages of Remineralized Water
- Remineralized water is absorbed by the body faster and quenches thirst better. When minerals are added back to the water, it will bring its pH level into an alkaline state. The water is then ionized in the process, making the water molecules cluster into smaller groups which are easier for the body to absorb.
- Remineralized water tastes better. While taste is subjective, the human palate is used to the flavor of water that has mineral content.
Remineralizing RO Water
There are two ways to add back minerals to RO water: automatically through the last stage of RO process and manually.
How to Remineralize RO Water Automatically
- Install an RO system that features a pH balancing filter. Alternatively, you may also buy a remineralizing cartridge that you can integrate into your existing RO system.
- Check your system manual for instructions on the recommended substance. Some RO systems use Calcite (calcium carbonate) while others use Corosex (magnesium compound). Some filters allow the use of both substances. Calcite brings the pH level of the water to 7.0 (neutral) while Corosex typically brings the pH level to above 7 (base).
- Your RO system or add-in remineralizing cartridge should contain a guide on the required amount of substance that you can add. Generally, it is dependent on water temperature, original pH of the water, and flow rate.
- Once added, you’ll be able to enjoy drinking remineralized water out of your RO system.
How to Remineralize RO Water Manually
If you don’t have an RO filter or cartridge that automatically adds minerals into your water, the other method is to do it manually. Different options are available:
1. Himalayan or Celtic Salt
Himalayan pink salt and Celtic sea salt contain more than 80 different elements and minerals that offer many health benefits. You can add a pinch of either of these salts to your glass of water. Leave it for a few minutes to give time for the salt to dissolve before drinking.

2. Pascalite Clay
If you want to add minerals in your water without affecting its taste, Pascalite-clay is a good option. This unique clay comes from the Wyoming’s Big Horn Mountains. Many people are already using this clay for treating burns, infections and skin problems. The Native Americans call this clay, “The Mud That Heals.”
3. Mineral Drops or Tablets
Mineral drops and tablets are the most widely available additives that can remineralize RO water. They are also inexpensive. The mineral contents in these drops and tablets vary depending on brand, but the most common are copper, manganese, chromium, iodine, iron, zinc and selenium. Most drops also contain magnesium. The minerals are in their ionic or electrolyte form, making them easier for the body to absorb.
4. Greens Blend
If you don’t mind drinking green water, adding greens blend to your RO water makes a healthy and energizing drink. This powder blend is commercially available in different flavors such as berry and lemon-lime. Unflavored blends are also available. Aside from mineral contents, greens blend also provides prebiotic, probiotic and antioxidant benefits.
5. Spa Water
Homemade spa water is also popular among people who want to add minerals back into RO water. You can add fruits, herbs, spices or vegetables of your choice. Spa water is a good substitute for soda and artificial juices.

6. Alkaline pitcher
An alkaline pitcher is a more convenient way of remineralizing RO water. It raises the pH level of the water and then adds back essential minerals including calcium and magnesium. This is no ordinary filter and depending on the brand and model, it may cost you between $50 and $100.
The reverse osmosis system is useful for screening and eliminating contaminants and even bacteria and viruses that may be present in your water system. However, the filtration process also gets rid of minerals that are useful to the body. Thankfully, there are different ways on how you can add back minerals to the water. It can be through an integrated or add-in filter in your RO system or adding minerals manually.
The best option ultimately depends on the type of mineral you want to add back as well the amount of money you are willing to spend.
