Ayurveda suggests copper since it is a potent antioxidant that supports healthy skin, aids digestion, delays the aging process, gets rid of pollutants, and stimulates the brain.
In Ayurvedic medicine, drinking water kept in a copper bottle or other copper vessel (referred to as a tamra jal) balances the three doshas in your body: vata, kapha, and pitta.
Additionally, water kept in a copper water jug turns naturally alkaline, assisting in the pH balancing of your body.
