Can you drink deionized water?

There are different types of water that are safe for human consumption, beginning with the tap water that is provided by the water district that serves your town or city. While tap water is considered safe, it does contain tiny parts or ions of various minerals.

“Tap water is usually full of ions from the soil (Na+, Ca2+), from the pipes, (Fe2+, Cu2+) and other sources.1” In order, the chemical names above refer to sodium, calcium, iron and copper. Magnesium is another common mineral that can be present in tap water. 

Deionized water is just what it sounds like; it’s H2O that has undergone a process of removing ions that came from the soil, pipes and other sources. Deionized water has many uses, such as in science and engineering laboratories, the production of medications and in bottled beverages, to control the taste. Given that it’s so pure, can you drink deionized water?

The science behind it

While you can drink it in small amounts, making it your main source of water is certainly not recommended. In a study published by the Journal of General Internal Medicine regarding the mineral content of different waters available in the United States, it was discovered that minerals in the water were actually beneficial to humans. 

“The study found that drinking water sources available to North Americans may contain high levels of calcium, magnesium, and sodium and may provide clinically important portions of the recommended dietary intake of these minerals.2” Because it removes a source of essential minerals from your diet, the potential side effects of drinking deionized water exclusively are quite severe. 

“Recent studies also suggest that the intake of soft water, i.e., water low in calcium may be associated with a higher risk of fracture in children, certain neurodegenerative diseases, pre-term birth and low weight at birth and some types of cancer.3

The benefits without the side effects

Why do we use deionized water in our supplements? Deionized water is a “blank slate,” so to speak, and will absorb the chemistry of whatever is added to it, preventing any interference with the beneficial element(s) in the supplement. We use it in our daily vitamins as well as other products, such as Silica Plus, so you get the full dose of the essential vitamin or mineral in the supplement. 

With so many manufacturers of nutritional supplements, how do you know which one will be the most effective? The ingredients and preparation of all of the products made by Vibrant Nutraceuticals adhere to the highest scientific standards. It’s our mission to produce the most organic, easily absorbed, bioavailable supplements available on the market today. You know you’re getting the highest quality when you purchase from Vibrant Nutraceuticals.
