Looking at the ingredients, there’s nothing in these that seems unsuitable for humans. But the directions say to dissolve half the package in 55 gallons of water, so have fun trying to figure out how much to put in your liter water bottle.

Simple, dissolve the whole package in one gallon of water, and then the solution is 110 times as potent as it should be.

Round up to 128 because watering it down a little more won’t hurt you, and that simplifies the math. You put one ounce of that gallon of solution into a second gallon of water, and you’re ready to drink. Repeat with a new gallon of tap water mixed with an ounce of your solution as needed.
