Now, don’t stress over this. Most people don’t need distilled water in their lives. If you’re healthy and eat a balanced diet, the minerals in RO water are negligible anyway. You get your calcium from milk and your magnesium from nuts, not from your faucet.
The real takeaway? If you want water that’s literally nothing but H2O, go distilled. If you want clean, pleasant-tasting water that’s still got a little life in it, go reverse osmosis. Both are great. Neither will make you grow a third arm.
