Independently verified

Every batch tested. Certificate published before sale.

Deuterium cannot be filtered out. It is chemically identical to hydrogen and differs only in mass, so removing it takes repeated industrial separation.

ppm, Yavelle

Which means the only thing that really matters is whether the number on the bottle is real. So we publish the laboratory certificate for every batch, before the water goes on sale.

What a real certificate contains

Worth knowing, and it applies to every brand in this category including ours.

  • A named laboratory. Not the phrase independently tested.
  • The method used. Ours is isotope ratio mass spectrometry.
  • A batch identifier matching the bottle in your hand.
  • A result with a stated uncertainty. A number without one is a number somebody typed.
  • An authorising signature.

A good number of brands in this category cannot produce one. We would encourage you to ask.
