Spring water! Plastic-Bottled its fine. Look for the one with the highest nutrients and lowest nitrates .

The best water to drink is naturally clean, pure and full of naturally occurring minerals like Well water, Natural spring water, Artesian or spring waters, Mineral water

I drink distilled from our own distiller. It's simply pure water using the oldest water purification process around. There's a lot of misguided hype dismissing distilled. Simply put, you get plain H2O and it's using simple chemistry/physics to ensure there are no contaminants. Given that we don't even test for the hundreds of contaminants in our water not to mention have specific filters for them, this is the most reliable. For minerals, I get them from my food - greens and nuts. Best way for your body to take them in as well.

Have never regretted my Waterwise distiller. Especially the more I examine the simple Science and see all the misguided water hype out there!
