Distilled water has virtually no calcium. This is because the distillation process removes minerals, including calcium, from the water.
Understanding Water and Calcium Content
Water hardness, often associated with high calcium and magnesium content, varies significantly depending on the source. Tap water typically contains various minerals, including calcium, while distilled water, often described as “pure water”, is nearly devoid of these minerals. [See references below for details on water hardness and mineral content.]
- Tap water: Contains varying levels of calcium, often contributing to water hardness. The calcium concentration can range significantly depending on the geographic location.
- Distilled water: Undergoes a distillation process that removes most minerals, including calcium. Therefore, it's characterized by a very low or undetectable calcium level.
- Spring water: May have low to moderate levels of calcium.
- Mineral water: Often contains a significant amount of minerals, including calcium, which are what give mineral water its unique taste.
The presence or absence of calcium in water doesn't automatically indicate whether the water is safe to drink. While calcium is a beneficial mineral, drinking water with very low calcium content is usually not harmful. However, long-term consumption of water lacking essential minerals might lead to deficiencies, but this is rare and is largely mitigated by a balanced diet.
Note: The level of calcium in water varies depending on the source and other factors. The information provided here is a general guideline.

- Another source indicates that distilled water doesn't contain minerals like calcium and magnesium found in tap water. (Source 2)
- A third source states that if calcium and other ions are removed from water, it could be considered distilled, reverse osmosis (RO), or deionized. (Source 3)
