remineralize water after reverse osmosis

Clean water is essential not to just quench our thirst. It is a basic human need if we are to stay healthy and alive. That is why we now have different types of water for consumption such as distilled, purified and mineral water.

One of the water purification processes used today is called Reverse Osmosis. In this process, water is moved through a semipermeable layer at high pressure. The end result is water that has no minerals or very little.

Why Remineralize Water?

Although there are several misconceptions surrounding this water filtration method, it is generally agreed that reverse osmosis technology has its benefits. The significant disadvantage of RO is that lots of dissolved solids get eliminated during the process. Although it’s certainly good to remove any unhealthy substances and chemical contaminants, in the process, RO also tends to remove minerals that are beneficial to our health. This makes remineralizing water important.

Ways Of Remineralizing Water

Reverse osmosis is a popular and widely used water filtration method. In the process, the water is passed through a semipermeable membrane. This is done at relatively high pressure and it leaves nearly all the dissolved solids behind. The water passing through reverse osmosis is, effectively, severely demineralized.

Although it goes largely ignored, there is significant evidence to show that consuming demineralized water may not always be healthy.  A logical solution, therefore, is to remineralize the water by adding back the essential minerals after filtration.

Add Alkalinization Stage to Your RO System

If your reverse osmosis system doesn’t already have an alkalinization stage, you can probably add it without too much stress. Study the market for an alkalinization model that fits your system and which uses quality food-grade minerals only.

Depending on your domestic water demand, the minerals can last from 6 to 12 months before the need to replace them arises. In addition, the nature of the water, the flow-rate, temperature, and the pH-level prior to entering the alkalinization stage will determine the number of minerals that need to be added back.

Add Mineral Rich Salt

To each gallon of the filtered water, simply add some natural salt such as Himalayan salt or any other rock salt. Remember, only a pinch of the salt is needed. There will be no significant change in the taste of the water and it will still taste pretty much like standard drinking water.

Another method is mixing a salt solution and storing it in a glass dropper bottle which you can then use to re-mineralize the water. Using table salt will not do because it’s only composed of sodium and chloride – rock salt is unprocessed and natural.

Electrolyte Blends/Mineral Drops

At times referred to as trace mineral drops, Electrolyte Blends are compositions of minerals like manganese, iron, copper, selenium, magnesium, and calcium. They are available at nearly all major supermarkets. Simply mix them back into your water after the RO process. The blends differ in composition depending on the brand.

These soluble minerals are simply not just for balancing alkaline and acidic variables. In addition, they enhance your body’s immune system. They reintroduce potassium bicarbonate, selenium, potassium citrate, potassium lactate, and other important trace minerals to the drinking water.

Buy Alkaline Water Pitcher

If your budget allows it, alkaline water pitchers are easily accessible and easy to use. Usually, this product comes at a premium but is a good buy because it will serve you for long. It not only re-filters the water but also balances the water’s pH levels.

Although alkaline water pitchers are not cheap, they are, however, easily available at specialty stores. Depending on your budget, there are different types available. It’s important to do your homework before buying to ensure you understand how it operates.  They are slightly more expensive than electrolyte blends or using mineral rich salts but they last longer.

Mineral Cartridges/Filters

A mineralization cartridge is made of those naturally occurring minerals recently taken from your water after the reverse osmosis. It is placed between the faucet and the water holding tank. This guarantees you that the water is flawless the moment it leaves your faucet.

The main ingredient in nearly all mineral cartridges and other remineralizing products is plain Calcite; pure calcium carbonate. If you want your water remineralized with mineral supplementation after reverse osmosis, then filtering through a small Calcite bed will meet that requirement.

While water straight from your Reverse Osmosis unit is great, when it goes through a Calcite filter, it comes out tasting exceptionally good. If you want your water to have a pH above the low 7’s, then get a Calcite cartridge that also has a pinch of Corosex.

Greens Blends

Greens blends are minerals extracted from plants and vegetables. This broad range of balanced minerals is good for your health. The downside is that they are not cheap because they are derived from the vegetables and plants themselves. They make an excellent alternative when you want to get back the minerals lost during the RO process. If your budget allows it, this is a great water remineralization option.

Green blends also make your water taste slightly different than what most people are used to and, therefore, you actually might not like it. Because green blends are not that tasty, they may not be agreeable for most. Since they are only available in powder form, they tend to be costly and may not be the best long-term water remineralization solution for those on a budget.


Reverse osmosis water is definitely not bad for your health. As a matter of fact, it’s essential to use RO filters in some places otherwise you become susceptible to a number of water-borne diseases. The good thing about reverse osmosis is that even if your water loses essential minerals, there are ways that can be used to bring them back.

If you want the most cost-effective method, then go for Himalayan salt. If a more sustainable method is needed, an alkalization stage incorporated into your Reverse Osmosis filter system works well. You can, if your budget permits buy an alkaline pitcher.

If you want to avoid the technical options, simply get back the lost minerals by consuming green blends. Ultimately, the choice you make will depend on your budget, lifestyle, and preferences.
