I recently learned that Ayurveda recommends storing drinking water in copper containers for positive health benefits.
Upon my simple experimentation, I've noticed the following effects:
Water Type : activated carbon filtered drinking water
Duration of storage: 8 hours
The taste of the water changed, it tasted more metallic. I think this is because of the increase of dissolved copper in the water.
If I'm drinking 4-5 liters of water per day, would that be still under the safe limit of 2 mg/day? ref 2 Note: I don't have any apparatus to measure the copper content in the water.
I've researched a bit and found that it does have some positive effects on killing some microbes such as bacteria ref 1. Note: I'm not able to deduce any conclusion about the increase in copper content from this paper even though the author said it is "within the permissible limits."
I would like to know more about the studies related to this claim and I'm really interested to know about the side effects.
