I've often heard that drinking distilled water is bad due to it leaching minerals/electrolytes. Has anyone done the math on this to either validate or debunk this?

A 16oz bottle of San Pellegrino has 20mg of sodium. How can such a small difference in sodium intake (and other minerals) have a meaningful influence on electrolyte levels?

It is a common misconception that drinking distilled water is dangerous. Water isn't a major source of minerals. [source](https://biology.stackexchange.com/a/7194)

Put salt in your water?

Wouldn't you taste that?

Yes, and it would improve the taste. If you like San Pellegrino, you can get a similar taste at much lower cost by adding "Burton Salts" (a blend of salts meant to imitate the water of Burton on Trent, which is famously well suited for making pale ales, widely available from brewing suppliers) to soft water.

And people have made spreadsheets to help with cloning specific mineral waters with the exact blend of salts, e.g.:

Very interesting, thank you!
