It is well known that in the past, society valued "copper," and drinking from a copper jug or glass has health benefits. However, we seem to have overlooked cobalt blue glass, even though it is considered number one in terms of healing.
The intake of vitamin B12 is recommended to combat various forms of anemia, promote the formation of erythrocytes, support the normal development of the nervous system and good eyesight, as well as to aid brain function and mood, and to provide energy and detoxify the body. Vitamin B12 is the only vitamin that contains the mineral cobalt.
So why not start drinking from a cobalt blue glass again, as was customary in the past?
