Any water you drink is already very much hypotonic relative to your bodily fluids. Your minerals mostly come from your food, not your water.

I’m no expert on biology (I’m a chemist), but I drank quite a bit of DI water in grad school because the tap water was so gross.

Also, heavy water (D2O) tastes sweet. And it also won’t kill you when consumed, contrary to urban legend (at least not in quantities you can reasonably afford).

True. The saline solution used for blood injections has 9000 ppm of dissolved solids. Whereas tap water above even ~200 ppm tastes disgusting to me.

Nice... but I wonder if it's considered food-grade, and if there are any non-ionic / non-polar impurities in it.

I find that plain distilled water tastes sweet too. I can't afford heavy water, but this YouTuber did: https://www.youtube.com/watch?v=MXHVqId0MQc .

Deuterium oxide will kill you only after deuterium replaces a significant portion of all your body's hydrogen atoms, like maybe 50+%. https://www.youtube.com/watch?v=fyK6kPi8k78
