Any tips on DIY salt pills / electrolyte replacement?

I was trying to figure out how to make inexpensive electrolyte pills. From my calculations, one could make the daily recommended equivalent (assuming no other food has said nutrients):

Table Salt - 1 tsp (primarily: NaCl, gives sodium)
Salt Substitute - 2 tsp (primarily: KCl, gives potassium)
Milk of Magnesia - 1 tbsp (primarily: Mg(OH)2, gives magnesium)
Antacid Tablets - 5 pills (primarily: CaCO3, gives calcium)

This could be useful to endurance athletes and people who are practicing prolonged water-only fasting.

Has any of you tried to make something like this before?
What other essential nutrients would you include?
Any recommendations for a phosphorus source?

AFAIK and I am unable to find a decent reference for this The so call electrolyte drinks are little better than water after exercise.

Beetroot juice has some benifits though.

Ok now this may sound weird but it works really good, pickle juice.

I like this frugal philosophy. Every part of the buffalo,

or in this case, every part of the jar of pickles, gets used for something.

The pickles themselves are food. The juice surrounding the pickles is homemade sports-drink precursor. The glass jar and its lid, these too are useful, since they can be repurposed as containment for something else.

What about the paper label, or the glue affixing the label to the glass jar, are these useful for anything? I dunno.

But, using every part of the buffalo, this is a noble goal.

Soak the Label off compost it and use the compost to grow pickles.

Regarding the first question, I have never tried to make my own electrolyte replacement mixture.

Using Instuctables' search function, I have tried to find 'ibles like what you describe containing words like, "electrolyte", "electrolyte drink", "salt pills", and I did not find much.

This one is basically Kool Aid(r) + table salt + sea salt:


I have no idea which ions are important, or in what doses, but it looks like you've got a good assortment there. The ions you mentions, matches the same ones listed here and here,


although, you must be figuring dosage from other sources, since those two Wiki articles do not mention any numbers for dosage.

The ingredients you've listed for your salt mixture, these are all pretty easy to find, which makes me wonder if this is one of the rules of the game. I.e. do the ingredients have to be something that can be bought in a typical supermarket or drug store?

On eBay, you can find a pretty wide selection of bulk, food grade, chemicals. For some of these, the price per kilogram ?might? be better than the supermarket version, assuming a supermarket version exists.

Actually, regarding cost, there might be some manufacturer who actually makes a complete "salt pill", and can sell it to you cheaper than you can make it. But of course, that would be SEDIFY, not DIY.

Back to the subject of eBay chemical mongers, I often see the phrase "food grade" in the titles of item listings, and I am naively assuming there is truth in that claim, if the seller is truthful. I am guessing the "food grade" version of chemical is guaranteed not to have poisonous impurities.

For example, I would assume food grade trisodium phosphate, is more safe to eat or drink, than trisodium phosphate (TSP) sold in hardware stores as a cleaning product.

Also on eBay you can probably find calcium phosphate, or magnesium phosphate, but I mention trisodium phosphate as an example of a chemical for which there might be a choice between food grade versus some other grade, not intended for human consumption.

Also you might be able to find natural sources for some of these chemicals. Maybe. For example, human urine has phosphates in it.

It's probably safer to drink your own urine, rather than someone else's.

Which reminds me, when I searched for 'ibles about "salt pills", I found this:


From the title, it looked like it might be what you were looking for, but no. This is all about purifying the dissolved solids in waste water. I am guessing the end product of this instructable is a substance NOT seriously intended for human consumption. The word "medicinal" in the title of this 'ible refers to the fact that this dried solid contains medicines excreted by the people whose sewage is upstream of this water source.

So yeah. When you drink other people's urine, you end up taking, in some amount, the same medicines they're taking. I guess that's the lesson, the "instructive" part, of that instructable.
