What Is Deuterium Depleted Water?

Deuterium depleted water, often shortened to DDW, is simply water that contains less deuterium than ordinary water. Deuterium is a naturally occurring heavy form of hydrogen found in all the water we drink, and deuterium depleted water has had some of it removed, leaving a purer, lighter water. Yavelle is a 25 ppm deuterium depleted water, meaning its deuterium level is well below what you find in normal drinking water.

That is the short answer. If you have come across the term and want to understand what it actually means, this guide explains deuterium, what the ppm number refers to, how the water is made, what it tastes like, and how people choose to include it in their day.

What is deuterium?

Deuterium is an isotope of hydrogen, sometimes called heavy hydrogen because it carries an extra neutron, which makes it heavier than the more common form. It occurs naturally everywhere, including in the air, in food and in every glass of water. It is a normal part of the water on Earth, just present in very small amounts.

What does the ppm number mean?

The ppm number stands for parts per million, and it describes how much deuterium the water contains. Ordinary drinking water sits at roughly 150 ppm of deuterium. Deuterium depleted water has been reduced below that natural level, which is what makes it different from the water that comes out of the tap or a standard bottle. Yavelle is produced at 25 ppm, so its deuterium content is a fraction of what is found in normal water.

How is deuterium depleted water made?

Reducing the deuterium in water is a careful, technical process. Because deuterium is slightly heavier than ordinary hydrogen, specialised separation methods such as fractional distillation can gradually lower its concentration, step by step, until the water reaches the target level. It is a slow and precise process, which is one of the reasons deuterium depleted water is a more specialised product than everyday bottled water.

What does deuterium depleted water taste like?

It tastes like clean, pure water. Removing deuterium does not add any flavour, so most people notice no difference in taste compared with a high quality still water. It is simply water, intended to be enjoyed the same way you would drink any other.

Why do people drink deuterium depleted water?

Deuterium depleted water has become an area of growing scientific interest, and research into it is ongoing. Some people choose to include it as part of a considered daily wellness routine, in the same way they might be mindful about the quality of the water and food they consume. It is best thought of as a premium water choice rather than a treatment, and the science is still developing, so we would encourage anyone interested to read widely and form their own view. Nothing here is a health claim, and deuterium depleted water is not intended to diagnose, treat, cure or prevent any disease.

How do people use it?

People generally drink deuterium depleted water as they would any other water, as part of their normal daily fluid intake. There is no special method to it. Some prefer to make it a steady part of their routine rather than an occasional drink, simply as a quality of life choice. As with any change to your diet or routine, if you have a health condition, are pregnant or are unsure, speak with a healthcare professional first.

Is deuterium depleted water safe to drink?

Deuterium depleted water is water, and is intended to be enjoyed as a normal drink. As always, if you have a specific medical condition, are pregnant, or have any concerns about your diet, it is sensible to check with your doctor or a qualified healthcare professional, who can give advice based on your individual circumstances.

Frequently asked questions

What is deuterium depleted water?
Deuterium depleted water is water that contains less deuterium, a naturally occurring heavy form of hydrogen, than ordinary water. Yavelle is produced at 25 ppm, well below the level found in normal drinking water.

What is deuterium?
Deuterium is an isotope of hydrogen, sometimes called heavy hydrogen because it has an extra neutron. It occurs naturally in all water, food and air, in small amounts.

What does 25 ppm mean?
Ppm means parts per million and describes how much deuterium the water contains. Ordinary water sits at roughly 150 ppm, while Yavelle is produced at 25 ppm, a fraction of the natural level.
