A combination of water, salt and citrus makes a good homemade electrolyte solution. Water helps with rehydration and serves as an electrolyte carrier. For best results, use distilled or spring water rather than tap water; distilled water is the purest option.
Ordinary table salt is a good source of electrolytes. Salt with potassium iodide provides added benefits. If the salt does not dissolve well in the solution, try grinding it first with a mortal and pestle.
Any citrus fruit is a good addition to the solution, but oranges are especially effective. Another homemade electrolyte solution recipe consists of a mixture of 1 liter of water with ? cup each of lemon and lime juice, 1 teaspoon of salt and one whole squeezed orange.
For another option, squeeze the juice of one lemon and one orange into a large glass. Add a little honey and a few shakes of salt. Fill the glass with water, and mix the ingredients well.
Another simple homemade electrolyte solution consists of a bottle or can of vegetable juice mixed with 1 cup of water and 1 cup of orange juice.
If you want to make a more complex electrolyte drink in a blender, try blending two bananas, 3 cups of coconut milk, 1 cup of water and ice, 1 teaspoon of salt and the juice of one-half of a lemon or an orange.
