Fact check: Does distilled water leach minerals from your body when consumed regularly?

Checked on June 11, 2025

1. Summary of the results

The scientific evidence strongly indicates that distilled water can indeed leach minerals from the body. This occurs because distilled water completely lacks essential minerals like calcium, magnesium, fluoride, iron, and sodium [1]. When consumed, the demineralized water actively draws minerals from body tissues and bones to achieve mineral balance [2].

2. Missing context/alternative viewpoints

Several important contextual points are missing from the original question:

  • The effect primarily becomes concerning with exclusive or heavy consumption of distilled water [3]
  • There are practical solutions available, such as taking mineral supplements or multivitamins when consuming distilled water regularly [2]
  • The water's effect on the body is related to a fundamental chemical principle: the water attempts to achieve mineral balance, which is why it draws minerals from tissues [2]
  • The issue isn't just about mineral leaching, but also about the water's inability to replenish necessary electrolytes the body needs [1]

3. Potential misinformation/bias in the original statement

The original question oversimplifies a complex issue by:

  • Not specifying what constitutes "regular" consumption
  • Failing to mention that the primary concern is with exclusive consumption rather than supplementary use
  • Not acknowledging that the effects can be mitigated through proper dietary supplementation

Who benefits from different narratives:

  • Water filtration and distillation companies benefit from downplaying these concerns
  • Mineral supplement manufacturers benefit from emphasizing these risks
  • Traditional water supply companies benefit from highlighting the advantages of naturally mineralized water over distilled water

The scientific consensus across all provided sources consistently supports the mineral-leaching effect of distilled water, making this a rare case where the evidence points strongly in one direction.
