Water remineralization is the practice of adding back mineral elements to purified drinking water. Consumers use advanced purification systems that remove contaminants but also strip out beneficial minerals. The goal is to restore the water’s composition to resemble natural spring water, which has a balanced profile of dissolved solids. This process improves water quality for both hydration and taste.
Why Certain Water Types Require Trace Mineral Supplementation
Trace minerals (e.g., iodine, zinc, selenium, and copper) are required by the body in very small quantities, typically less than 20 milligrams daily. They differ from macro minerals (e.g., calcium, magnesium, potassium, and sodium), which are needed in larger amounts. Macro minerals often receive more focus in water remineralization because they significantly impact flavor and hydration.
Modern purification methods, such as Reverse Osmosis (RO) and distillation, are highly effective at removing contaminants but are indiscriminate. RO systems force water through a membrane, filtering out up to 99.5% of dissolved solids, including both macro and trace minerals. Distillation strips the water of nearly all dissolved inorganic compounds by boiling and condensing the steam.
This purification results in demineralized water, which has a flat taste due to the absence of mineral content. Purified water lacks the natural mineral balance found in spring water. Adding minerals back enhances the water’s palatability and restores a complete electrolyte profile for optimal hydration.
Accessible Methods for Adding Trace Minerals
The most accessible method for remineralizing water uses high-quality, mineral-rich salts. These salts are minimally processed and contain a broader spectrum of elements than standard table salt, which is often just sodium chloride. Salts like Celtic sea salt or Himalayan pink salt are frequently used because they naturally contain over 70 different trace elements.
A small amount of these salts can be added to purified water to reintroduce minerals and improve flavor. A common recommendation is to dissolve approximately one-eighth of a teaspoon into a liter of purified water. Celtic sea salt is often preferred for mineral addition due to its lower sodium content and higher concentration of magnesium and calcium compared to Himalayan pink salt.
Another highly concentrated method uses liquid trace mineral concentrates. These are typically derived from ancient sea beds or salt lakes, such as the Great Salt Lake in Utah. Commercial drops are processed to remove most sodium while concentrating ionic trace minerals, including magnesium, chloride, potassium, and boron. They offer a simple, measured application, usually requiring only a few drops per glass or up to 40 drops per gallon. The minerals in these liquid supplements are in an ionic form, which enhances their bioavailability and effectiveness for supporting the body’s electrical systems.
Ensuring Proper Mineral Balance and Intake
While remineralization is beneficial, avoiding over-supplementing is important, as excessive mineral intake can lead to health issues. Consumers can monitor the concentration of dissolved inorganic solids using a Total Dissolved Solids (TDS) meter. A TDS meter measures the water’s electrical conductivity, providing a reading in parts per million (ppm) that relates directly to the amount of ionized salts and minerals present.
The optimal TDS range for drinking water, balancing taste and general health benefits, is typically 50–150 ppm, though water is considered acceptable up to 500 ppm. Testing the water before and after adding minerals helps users determine the appropriate dosage to reach this target range. A high TDS reading confirms a high mineral level, which can affect taste.
Signs of excessive mineral intake, or mineral toxicity, manifest differently depending on the specific mineral. For example, too much sodium can lead to high blood pressure, while excessive magnesium may cause a laxative effect. Symptoms often include digestive upset, such as nausea or bloating, or issues like muscle cramping or electrolyte imbalance. If you experience persistent negative symptoms while using remineralization products, or if you are concerned about a pre-existing mineral deficiency, consult a healthcare professional for personalized guidance.
Water remineralization is a growing practice among health-conscious consumers who use advanced purification systems to ensure their drinking water is free of contaminants. This process involves deliberately adding back mineral elements that are typically removed during rigorous filtration. The goal is to restore the composition of purified water to a state that is more akin to natural spring water, which offers a more balanced profile of dissolved solids. This practice aims to replace these elements, which are often stripped out alongside impurities, thereby improving water quality for both hydration and taste.
Why Certain Water Types Require Trace Mineral Supplementation
Trace minerals are elements required by the human body in very small quantities, generally less than 20 milligrams per day, and include nutrients like iodine, zinc, selenium, and copper. These are distinct from macro minerals, such as calcium, magnesium, potassium, and sodium, which are needed in much larger amounts for various bodily functions. While both types are important, macro minerals often receive more attention in water remineralization due to their impact on flavor and hydration.
Certain modern water purification methods are highly effective at removing undesirable contaminants, but they are indiscriminate, removing beneficial minerals alongside harmful substances. Reverse Osmosis (RO) systems, for instance, force water through a semi-permeable membrane that filters out up to 99.5% of dissolved solids, including macro and trace minerals. Distillation, which involves boiling water and condensing the steam, also effectively strips the water of nearly all dissolved inorganic compounds.
This process results in demineralized water, which is described as having a flat or neutral taste due to the absence of mineral content. While purified water is exceptionally clean, it lacks the natural mineral balance found in spring water, which typically contains a mix of calcium, magnesium, and potassium that contributes to its crisp taste. Adding minerals back is therefore often necessary to enhance the palatability of the water and restore a more complete electrolyte profile for optimal hydration.
