For thousands of years, Ayurvedic physicians prescribed drinking water stored overnight in copper vessels as a daily tonic. They called this practice Tamra Jal — copper water — and attributed to it remarkable healing powers. Today, peer-reviewed science is catching up with these ancient claims, and the results are compelling.
At PGD, we handcraft and export 99.9% pure copper bottles to health-conscious consumers across North America, Europe, and the UAE. Here, we break down the science behind seven key benefits of making copper your daily drinking vessel.
1. Natural Antimicrobial Properties
Perhaps the most well-documented benefit of copper is its ability to destroy harmful microorganisms. A landmark 2012 study published in the Journal of Health, Population and Nutrition found that water stored in copper pots for just 16 hours showed a significant reduction in Vibrio cholerae, E. coli, and other dangerous pathogens — without any chemical treatment.
This is known as the oligodynamic effect — copper ions leach slowly and safely into water, disrupting the cell membranes of bacteria and viruses at a molecular level. The effect is particularly pronounced at room temperature.
"Copper is nature's antibiotic. It actively fights contamination, making it ideal even for communities without access to treated water."
Dr. Priya Mehta, Ayurvedic Research Institute, Pune
2. Supports Healthy Digestion
Copper stimulates peristalsis — the rhythmic contraction of stomach muscles — reduces inflammation in the stomach lining, and destroys bacteria responsible for stomach ulcers and infections. Drinking a glass of copper-charged water on an empty stomach each morning is one of the oldest Ayurvedic digestive prescriptions, and clinical nutritionists are now recommending the same practice.
3. Supports Brain Function
The brain transmits impulses via myelin sheath synthesis, a process that requires copper. Copper helps the body synthesise phospholipids essential for forming the myelin sheaths that coat nerve fibres. Research links copper deficiency to cognitive decline, slowed neural transmission, and neurological disorders. Regular copper water intake contributes to meeting this often-overlooked mineral requirement.
4. Cardiovascular Health
Research published in the American Heart Journal notes that copper plays a critical role in regulating heart rate and blood pressure, lowering LDL (bad) cholesterol, and maintaining the elasticity of blood vessels. A 2015 meta-analysis found that copper deficiency was statistically associated with elevated cardiovascular disease risk — particularly in populations with diet-related mineral deficiencies.
5. Anti-Inflammatory Effects
Copper has well-established anti-inflammatory properties and has been used for centuries to relieve the pain of arthritis and joint inflammation. Modern studies confirm that copper peptides in drinking water can reduce systemic inflammatory markers. For those managing chronic inflammation, copper water is a simple, zero-cost adjunct therapy.
Pro Tip: For best results, fill your copper bottle with clean filtered water each evening and drink two glasses on an empty stomach in the morning. This allows maximum copper ion infusion without risk of over-saturation.
6. Boosts the Immune System
Copper is essential for the synthesis of white blood cells — the foundation of immune defence. It supports the body's ability to fight infections and accelerates recovery from illness. One or two glasses of copper water daily can contribute meaningfully to meeting the recommended daily copper intake of 0.9 mg for adults, particularly for those who don't eat shellfish or nuts regularly.
7. Ayurvedic Balance — Tridoshic Harmony
Ayurveda classifies all physiological forces through three energies, or doshas: Vata (air/space), Pitta (fire/water), and Kapha (earth/water). Copper water is considered tridoshic — uniquely capable of balancing all three doshas simultaneously. This is exceptionally rare among natural remedies and explains why Tamra Jal has been central to Ayurvedic medicine for over 5,000 years.
How to Use Your Copper Bottle
- Fill with clean, filtered water — not flavoured drinks, juice, or milk
- Allow to sit for at least 6–8 hours, ideally overnight at room temperature
- Drink 2–3 glasses daily; first thing on an empty stomach is most effective
- Do not refrigerate — room temperature is optimal for copper ionisation
- Do not store acidic liquids (lemon juice, vinegar) for extended periods
Care & Maintenance
Genuine copper will naturally develop a patina — a thin, darkened, or faintly greenish layer called verdigris — over time. This is completely normal and non-toxic. To restore the original copper shine, scrub the interior with a paste of salt and tamarind, or salt and lemon juice. Rinse thoroughly with water. Store your bottle dry when not in use.
