Here’s where things get a little personal. Distilled water is so pure that it can actually leach minerals from your body if you drink it exclusively. Don’t panic! You’d have to chug it like a fish for months to see any issues. Still, it’s not ideal for everyday sipping. RO water retains trace minerals, so it’s kinder to your teeth and bones. Plus, it removes most of the bad stuff (like arsenic and nitrates) without making your body feel robbed.
Both are way better than tap water in places with high lead or chlorine—but for daily hydration, RO is the winner. Just don’t forget to eat your veggies too, okay? Water isn’t a meal.
