While copper water vessels have been used for millennia in Ayurvedic tradition, modern scientific research is beginning to shed light on the mechanisms behind their health benefits. Here's what the research actually says.
Copper's Antimicrobial Action
A 2012 study published in the Journal of Health, Population and Nutrition found that water stored in copper vessels for 16 hours at room temperature significantly reduced the presence of harmful bacteria. The study concluded that copper vessels could be a practical solution for water purification in developing countries.
The Oligodynamic Effect
The antimicrobial properties of copper are due to what scientists call the "oligodynamic effect" — the ability of small amounts of metal ions to have a toxic effect on microorganisms. Copper ions disrupt the cell membranes of bacteria, preventing them from reproducing and eventually killing them.
Trace Mineral Absorption
When water is stored in a copper vessel, trace amounts of copper leach into the water. The WHO recommends a daily copper intake of 0.9mg for adults, and copper-infused water can contribute to meeting this requirement. Copper is essential for iron absorption, collagen production, and immune function.
Important Considerations
While the benefits of copper water are well-supported, it's important to use copper vessels correctly. Only store plain water (not acidic beverages) in copper bottles, and clean them regularly to prevent excessive copper leaching. The copper content in properly used copper vessels is well within safe limits.
Our Commitment to Quality
