Making your own electrolyte drink is straightforward: combine one liter of clean water with half a teaspoon of table salt and six level teaspoons of sugar for a World Health Organization-approved oral rehydration solution.
Commercial sports drinks are convenient, but they often come with artificial colors, sweeteners, and a price tag that adds up fast. The good news is that you can mix a more effective electrolyte drink at home using ingredients already in your kitchen. The recipe you need depends on whether you’re fighting dehydration from illness or fueling a long run. Either way, the ratio of salt to sugar to water is what makes it work — and it only takes about two minutes to prepare.
What Makes an Electrolyte Drink Work?
The human body loses water plus key minerals — primarily sodium, potassium, and magnesium — through sweat and illness. Replacing those in the right proportions matters more than any flavor additive. Sodium pulls water into the bloodstream, and sugar at the right concentration helps the gut absorb both water and sodium faster. The World Health Organization’s standard oral rehydration formula nails this balance exactly, and it costs pennies per liter.
The WHO Basic Recipe: The Gold Standard
This recipe is the most researched and trusted formula for preventing or treating dehydration, especially from diarrhea, vomiting, or intense exercise.
Ingredients
- 1 liter (4¼ cups) clean drinking water — use bottled or distilled if tap quality is uncertain
- ½ level teaspoon table salt (not coarse, not reduced-sodium)
- 2 tablespoons (6 level teaspoons) white sugar or honey
Combine all three in a pitcher and stir until fully dissolved. Taste it if you like, but taste alone cannot tell you whether the sodium level is correct. The measurement must be exact — too much salt worsens dehydration, and too much sugar has the same effect. Store the drink in the refrigerator for no longer than 24 hours; discard it after 12 hours at room temperature.
For a version closer to modern oral rehydration solutions, GoodRx recommends a reduced-osmolarity formula: 1 liter water, ⅜ teaspoon table salt, ¼ teaspoon sodium-free salt substitute (for extra potassium), ½ teaspoon baking soda, and 2 tablespoons sugar. This version has less sodium than the basic formula and matches what many commercial brands use.
DIY Athletic Electrolyte Drink: Coconut Water Base
Runners and athletes often prefer a recipe that provides natural potassium and tastes more like a sports drink than salty water. Nourished by Nic’s coconut water base is a popular starting point that works well for workouts under two hours.
- 1 large pitcher of coconut water (unsweetened, with no added flavors)
- Juice of 1 lemon or lime
- 1–2 tablespoons raw honey or maple syrup
- ¼ teaspoon sea salt
- Splash of fruit juice for flavor variety (optional)
Stir everything together and chill before your workout. Coconut water provides natural potassium and a bit of sugar already, so you need less salt and sweetener than the WHO recipe. Be aware coconut water brands vary significantly in sugar content — check the nutrition label and adjust the honey down if needed. This beverage works best for moderate activity, not for severe dehydration.

Common Mistakes That Ruin a Homemade Electrolyte Drink
The most frequent error is using rough estimates instead of actual measuring spoons. A half cup of salt instead of half a teaspoon produces a dangerously salty drink that can worsen dehydration. Taste is not a reliable guide — the solution should be mixed by volume, not by tongue. High sugar intake is another trap: adding syrup to already sugary juice creates a hyperglycemic drink that pulls water into the intestines rather than into the bloodstream. Always pair extra sweetener with extra water when using fruit juice as a base.
Storage matters too. Leftovers kept at room temperature beyond 12 hours should be discarded, and even refrigerated batches are best used within 24 hours. Measure each batch fresh rather than trying to stretch an old one.
When to Reach for Electrolytes vs. Plain Water
Plain water works fine for everyday thirst and short, low-intensity exercise. You need an electrolyte drink when you have been sweating heavily for over an hour, have had vomiting or diarrhea, or are exercising in hot conditions. The Cleveland Clinic recommends limiting homemade electrolyte drinks to 16 fluid ounces per day on a normal active day to avoid overloading on sodium and potassium. For extended endurance events, match your intake to your sweat rate rather than drinking a fixed amount.
If you prefer a grab-and-go option, you can find tested products that match the same ratios without the mixing. Our roundup of the best beverages with electrolytes covers store-bought options that work for athletes and everyday hydration alike.
Serving-Size Guide: Pick Your Single Serving
| Purpose | Liquid Volume | Salt | Sweetener | Extra Potassium |
|---|---|---|---|---|
| Quick rehydration | 16 oz water | ¼ tsp | 1 tbsp sugar | None needed |
| Post-run recovery | 20 oz coconut water | ⅛ tsp | 1 tsp honey | Already in coconut water |
| Keto workout | 16 oz water | ½ tsp sodium chloride | 0 | 1/15 tsp potassium chloride |
| Illness rehydration | 8 oz WHO formula | Use WHO ratios scaled down | Use WHO ratios scaled down | Per WHO formula |
Two Rules for Safe DIY Electrolytes
Always start with clean water — bottled or distilled if your tap is questionable. And always measure salt precisely using a proper measuring spoon. The difference between a helpful drink and a harmful one is a fraction of a teaspoon. For the lowest margin of error, use the WHO formula as your template; it has saved more lives than any sports drink and costs next to nothing to prepare.
FAQs
Can I use sea salt instead of table salt in electrolyte drinks?
Yes, fine sea salt works because it contains the same sodium chloride by weight. Just use a measuring spoon to keep the amount exact. Coarse salts like kosher take up more volume per teaspoon, so you would need slightly more to match the sodium content — stick with finely ground salt for reliability.
Gatorade vs. homemade electrolyte drinks — which is better?
A properly measured homemade drink matches Gatorade’s electrolyte profile for a fraction of the cost and without artificial dyes. Gatorade’s advantage is convenience and consistent flavor. For serious dehydration or illness, the WHO formula is actually more effective than most commercial sports drinks.
How long does homemade electrolyte drink last in the fridge?
Refrigerated homemade electrolyte drinks stay safe for up to 24 hours according to Alberta Health Services and should be discarded after 12 hours if left at room temperature. Make only what you plan to use within a day, and shake or stir before drinking because settled minerals can concentrate at the bottom.
Can I drink homemade electrolytes every day?
Not unless you are losing significant fluids daily through illness or intense exercise. The Cleveland Clinic suggests limiting intake to 16 ounces per day on a normal active day. Your kidneys regulate electrolyte balance effectively, and excess sodium from daily use puts unnecessary strain on your system.
Is it safe to give homemade electrolyte drinks to children?
Yes, the WHO basic formula is designed specifically for children and infants with diarrhea. Scale the serving size to the child’s body weight and never add more sugar or salt than the recipe calls for. For children under two, consult a pediatrician before using any electrolyte drink, including store-bought ones.
