Where is the site you quoted this from? Link? Don't tell me they are selling distillers to.
Anyways, I think adding the lemon juice in the ML drink has the same effect that they are claiming the distilled water offers. Calcium Hydroxide that we use in the ML drink is also inorganic, so according to this article you quoted the ML drink is bad for us? A tablespoon of pickling lime water added to a glass of water is quite a bit of inorganic mineral compared to filtered tap water.
