Inquiries about usage

Deposits are seen in the bottle. May I drink it?

Such a phenomenon can happen when calcium contained in alkaline ionized water is deposited.
It appears as pH is higher, original water has more minerals and ionization is made better. It doesn’t happen in purified water, bottled water and tap water.
Calcium scales attached in the bottle can be removed cleanly through washing it with diluted vinegar or citric acid.

Inquiries about usage

I worry if our body is alkalized after drinking alkaline water long.

Our gastric juice is strongly acidic.
Three liters of gastric juice is secreted every day and we should drink more than 3,000 liters of alkaline water to alkalize our body, so it actually is impossible.
A problem is that our body is acidified, so you don’t have to worry about our body being alkalized after drinking alkaline water too long.
Alkaline reduced water is healthy water containing various minerals which are good for our body and it is good for people to take it with alkali foods, such as spinach and brown seaweeds together as much as possible.
