Let’s look at what alkaline water means. When talking about the electrocuted version created in a water ionizer, it is likely a good idea not to drink it. If one drinks it anyway, then a short duration is recommended. This type of water is man made, out of balance and unsustainable. You can read more about this in the Beyond Alkaline Water Ebook.
In contrast, if your water is naturally enhanced with alkaline minerals such that the pH rises, you can drink as much of as you desire. Aspects of life move us toward acidity. Balancing this acidity naturally is beneficial.
Alkaline water from an ionizer is not natural.
Alkaline water such as from the Jivara Mountain Spring is natural.
