Deuterium depleted water is not a new discovery, but even though it’s been around for quite a while now, it still raises some questions that we’re going to address in this article.

To help you better understand why deuterium depleted water matters, we’re going to discuss the most frequently asked questions about it, show how you can control the deuterium level in your body and water, and how to drink deuterium depleted water (DDW).

But first, let’s see what exactly is DDW?

What is Deuterium Depleted Water?

DDW or lightwater is water that has been — partially or completely — cleared of heavy water.

Deuterium, also known as heavy hydrogen, is basically a non-radioactive, naturally occurring variation of hydrogen. 

While the atomic nucleus of hydrogen consists of one single proton, in the case of the deuterium nucleus the components are different, since this variation contains one proton and one neutron.

This twofold difference in the combination leads to other significant differences in the physical and chemical properties of hydrogen and deuterium.

The first innovative deuterium depleted drinking water, Preventa, was developed by HYD LLC and licensed by the Budapest Veterinary Health and Food Control Station in 1999. 


How is Deuterium Content Determined?

Deuterium content in water can be easily measured by mass spectrometry and innovative laser-based techniques.

The deuterium content is given in parts per million units (ppm), which clearly determines the abundance of deuterium in water, namely of one million hydrogen atoms how many are deuterium or how many of one million water (H2O) molecules are heavy water (D2O).

Each deuterium depleted water is rated with different numbers, which indicate the deuterium content in ppm units.

Preventa drinking waters contain significantly lower deuterium content than natural values and the degree of depletion is much higher than the natural deuterium level.

The numbers are easy to understand, Preventa 125 contains 125 ppm, Preventa 105 contains 105, Preventa 65 contains 65 ppm deuterium, and so on.


How about the Deuterium Content of the Human Body?

The deuterium content of living organisms or, in this case, of the human body, can be determined by knowing the deuterium content of oceans and of precipitation reaching the ground.

In our climatic zone, the deuterium content of surface waters is approximately 140-150 ppm. Using this data, we can determine the deuterium content of water in the human body.

We all know that 60% of the human body is water and this amount of water slowly decreases during our lifetime.

Since some organic compounds also have a certain amount of deuterium, the human body contains a much higher deuterium concentration than the normal level of elements such as calcium, magnesium and potassium. Therefore, a reduction of deuterium levels is needed.

How to Lower the Deuterium Content of the Human Body?

Lowering the deuterium content of the human body is an achievable goal. The most relevant and obvious method is to consume deuterium depleted drinking water.

By doing so, the deuterium content in our body will be significantly decreased. How? The normal water in our organism will mix with the deuterium depleted water, leading to a lower deuterium concentration in our body.

Another way to lower the deuterium content of our body is to consume deuterium depleted foods. These plants and foods are grown under special deuterium depleted condition, so even their organic molecules are low in deuterium.


Why Should we Drink “Lightwater”?

According to recent studies and research, lowering the deuterium content in the tissues and organs is a natural biological process all living organisms do.

Our body is naturally able to do this, however, factors such as ageing, sickness and the lack of exercise or sunlight can have a bad impact on completing this procedure.

By drinking deuterium depleted water, we can help this natural process by simply consuming less heavy water (D2O).

Keeping the deuterium content low can be easily done by consuming proper water and food. This way our body won’t have to deal with so much maintenance when it comes to targeting high deuterium concentration.


What is the Recommended Daily Amount of Deuterium Depleted Water?

First of all, when determining the amount of deuterium depleted water you should drink per day, it is essential to minimize the intake of fluids that contain water including soft drinks, milk, fruit juices, tap water, mineral waters).

It is recommended to avoid mixing normal water with low-deuterium water.

For an adult with an average body weight, the ideal water intake is 1.5-2 litres per day. By consuming this amount of deuterium depleted water, your daily need will be covered. You can even use deuterium depleted water for cooking or making coffee or tea.


Is Carbonated DDW Better or Should You Drink Non-Carbonated DDW?

This question is frequently asked by both normal deuterium water and deuterium depleted water consumers.

It is essential to understand that mineral waters and drinking waters are available in both carbonated and non-carbonated forms.

Basically, there is no significant difference between the two types of waters, they are equal in quality and have the same components when it comes to mineral content.


How to Reduce the Deuterium Level in Water?

Now that we know what deuterium depleted water is, let’s see how it’s produced and how to reduce deuterium level in water.

Water that is stripped of deuterium is produced by using an energy-demanding technology based on the significant differences in the physicochemical properties of normal water and heavy water.

Thanks to the boiling point difference of 1.5°C, the concentration of heavy water (D2O) is decreased in the vapour phase and this point makes the producing of deuterium depleted water possible. By following the same procedure and repeating the vapour phase, the deuterium content can be lowered to any level.


Can you Decrease the Deuterium Level of Your Water at Home?

Home distillers can decrease deuterium, although not substantially. Single distillation achieves a 1 ppm reduction, while double distillation offers a 2-3 ppm reduction.

This is an insignificant change in the deuterium level of water. While Preventa products contain 15-84 % less deuterium concentration than natural water, a home distiller can reduce the deuterium level by a maximum number of 1-1.5%.

These numbers clearly show that DIY methods aren’t efficient in getting rid of deuterium from water.


Final Thoughts

As you can see, a substantial decrease of deuterium concentration in water is only possible by fractional distillation, which home distillers aren’t able to achieve. This means that you can’t produce deuterium depleted water at home.

Preventa offers various types of DDW and the lower the deuterium content, the better. To further enhance the efficiency of this water and for best results, it’s recommended that you also consume deuterium-depleted foods.
