Drinking water stored in a copper water bottle has been a practice rooted in traditional Ayurvedic medicine for centuries. While scientific evidence on some claims is limited or still emerging, here are the commonly cited benefits—with notes on what is supported by science and what is more anecdotal or traditional:
✅ Scientifically Supported or Plausible Benefits:
Antimicrobial Properties:
Copper has natural antimicrobial effects. Studies (including those by the WHO) show that copper surfaces can kill harmful bacteria like E. coli and Salmonella.
Storing water in a copper vessel for 6–8 hours may reduce microbial contamination, especially in areas with questionable water quality.
Supports Immune Function:
Copper is essential in small amounts for proper immune system function, helping the body produce white blood cells and enzymes that fight infections.
Antioxidant Role:
Copper helps reduce free radical damage through its role in enzymes like superoxide dismutase (SOD), which has antioxidant properties.
