Homemade electrolyte mix, 1-10 cents/serving

Mixing them in the right proportions can be difficult, particularly if you are adding magnesium or calcium. What I ended up doing was mixing about 1000 servings at a time - weighing each ingredient with a precision scale. I then put all the salts in a food processor to mix them. This worked well, however the fine powder that results tends to clump (due to moisture I think), and storing the powder in a container with a desiccant helped keep it powdery.
