Introduction: AFFORDABLE and EASY Electrolyte Water

About: General all around DIYer!!!

We all know how important it is to stay hydrated or replenish the water that you sweat out while exercising or doing any sort physically demanding activity. BUT do you know that you sweat out more than just water? Part of what you lose through sweating are electrolytes, which one could argue are equally, if not more important, to replenish.

What are electrolytes?

In a nut shell, electrolytes are charged minerals responsible for fluid (water) travel in and out of cells, triggering action potential, enzyme production, etc. The most common being Sodium, Potassium, Magnesium, and Calcium.

Why do we need them?

Without electrolytes, you would find it very difficult to get water into your cells (to hydrate your body) as some of them, namely sodium and potassium, act as the gatekeepers of your cells. We've all heard a performance athlete referred to as a "well-oiled machine." In this analogy the athlete is likened to a machine, let's say a car. Food and water is the fuel that the car runs on for energy, electrolytes are the oil that makes sure that all the moving parts run smoothly and efficiently. When a car is low on oil, a check engine light comes on to notify the driver of the deficiency. The same is true of the human body. Muscle cramping, muscle weakness, fatigue, are all the body's little "check engine lights" telling us that something is wrong. Also, like a car, it is best to address these deficiencies before those lights come on, before it might already be too late. In a car, you can usually see signs that you are losing oil in form of a puddle under the car. In the human body, it manifest as sweating when performing some sort of physical activity. This is the context for my recipe.

NOTE: Electrolyte replenishing is not an exact science in that different people have different requirements based on age, weight, level of physical conditioning, genetics, etc. This is just a starting point, don't be afraid to tweak it as needed. :)

With that, proceed and experiment at your own risk. If you have any concerns, consult your doctor or medical professional first. Thank you!

Step 1: Ingredients

In the game of sport rehydration, sodium is king! Sodium is the biggest facilitator of water into the cells. Followed by potassium and magnesium, with calcium bringing up the rear. All that considered, and compared to many different (expensive) health food store electrolyte supplements, I have come up with a desired breakdown as follows:

Sodium: 300-400mg

Potassium: 100-300mg

Magnesium: 25-75mg

Calcium: ~25mg

As I stated before, this is just a starting point and may require you to increase or decrease different doses as needed. YMMV.


1/16 teaspoon baking soda = 153.5mg sodium

5/16 teaspoon Morton's Lite Salt = 175mg potassium and 145mg sodium

1/8 teaspoon epsom salt = 60mg magnesium

1 Calcium tab = 600mg* (we only need 25mg per dose)

At least 16 ounces of water.

*A couple things about the Calcium tabs. Buy whatever is cheapest. They will all be in a much higher dose than need for a single dose of the electrolyte powder we are making, which will dictate how we scale up each of the other ingredients in the batch. Calcium tabs come in many different strengths so you'll have to do a little math to figure out what you'll need. One last thing about the calcium, most calcium supplements are in a Calcium Carbonate form which is not water soluble. What that means is that it won't dissolve completely in the water. SO before you take a swig, just make sure to give it a good shake and you're good to go! :)

Step 2: The MATH!


1/16 teaspoon baking soda = 153.5mg sodium

5/16 teaspoon Morton's Lite Salt = 218.75mg potassium and 181.25mg sodium

1/8 teaspoon epsom salt = 60mg magnesium

1 Calcium tab = 600mg* (we only need 25mg per dose), 1 tab is roughly 1/2 teaspoon (1/48 teaspoon per dose! A really small amount!)

NOTE: To make it easy, each dose will be 1/2 teaspoon. The volume of the calcium is negligible so we basically won't account for it. The final strengths of everything else will be very slightly less than calculated but like I said, it's not an exact science.

As I previously stated, 1 calcium tab (that I am using) is 600mg but we only want 25mg per dose so:

600mg/25mg=24 doses.

This means we have to multiply the rest of the ingredients, that are already in single dose quantities, by 24.


24 x 1/16 teaspoon = 1&1/2 teaspoons of the baking soda.

24 x 5/16 teaspoon = 7.5 teaspoons = 2&1/2 tablespoons of the Morton's Lite Salt.

24 x 1/8 teaspoon = 3 teaspoons = 1 tablespoon of epsom salt.

~1/2 teaspoon/1 tab calcium.


Sodium = ~334.75mg

Potassium = ~218.75mg

Magnesium = ~60mg

Calcium = ~25mg

Step 3: The Final Product

I used a mortar and pestle to grind the tablet of calcium into a powder. The insides turns to powder pretty easilybut there is a thin skin that encapsulates the tablet, just give it a good grinding and it will all but disappear into the powder. Now just mix the rest of the powders as calculated and that's it! Like I said EASY!

To store it, is up to you! I prefer to keep it in a zip-lock baggy with a 1/2 teaspoon measuring spoon for easy dosing. As for how to mix it, add a 1/2 teaspoon to at least 16 ounces of water.

OPTIONAL: You can add lemon/lime juice or herbal tea or whatever you want for flavor.
