I've been making my own electrolyte drink for years, pretty much ever since I started following a low-carb diet and learnt about the keto-flu — the hard way!
Making your own electrolyte drink is super easy. Not only it's sugar free but it tastes so much better than any products I've tried. If you keep it simple without berries, the net carbs per serving will drop to only 1.7 grams.
Or you can add more flavor by using berries and make a batch of my Keto Blueberry & Lemon Electrolyte Drink, or this delicious Strawberry & Lime Electrolyte Drink.
In this recipe I used my Low-Carb Strawberry Syrup. It's smooth and creamy and apart from this keto electrolyte drink, it's great for mixing with just sparkling water, or drizzled over some Keto Vanilla Ice Cream. Yum!
Recipe Tips and Swaps
If you're worried about the carb count, feel free to reduce the amount of strawberry syrup in this recipe. It's really easy to do that in our KetoDiet App! All of the meals that I share here are automatically posted in the App where you can clone and modify them to your liking.
Here are tips for making sugar-free electrolyte drink at home:
- Drink with meals (not on an empty stomach). Start with a cup per day and increase to no more than 2 cups per day to avoid stomach discomfort. Too much magnesium citrate causes loose stools so keep that in mind. One cup will provide about 50% of your daily magnesium and two cups will cover your daily needs.
- Instead of potassium chloride, you can use lite salt or cream of tartar. To read more about potassium supplements, check out this post: The Importance of Potassium in Low-Carb Diets.
- Instead of Erythritol, you can use other healthy low-carb sweeteners from this list, or skip the sweetener altogether.
- If you don't like sweeteners, they can be omitted.
- Nutrition facts in blueberries are estimated and counted partially (80%) as part of the pulp and the peel are discarded.
Step-by-step
Prepare the Low-Carb Strawberry Syrup. If you have this ready, it will only take 5 minutes to make this electrolyte drink recipe. Otherwise, you'll need about an hour to make the syrup and chill it. You will only need 1 1/2 cups so store the remaining syrup in the fridge.
Juice the limes. Instead of limes you can use lemons.

Pour the water into a large jug or a large mason jar. Add the strawberry syrup.

Add the lime juice, potassium chloride, salt and magnesium powder.

Stir to combine (it will foam). Taste and add stevia or other low-carb sweetener if needed. Let it sit until the fizzing has completely settled (this is essential for best magnesium absorption).
Place ice in a serving glass and pour in the strawberry lime electrolyte drink (about 1 cup/ 240 ml per serving).

Serve chilled over ice. Store the strawberry lime electrolyte drink in the fridge for up to 4 days. Stir before serving.

Can't believe how easy this was to make — definitely making it again! I get the worst keto-flu sometimes and been searching for a good homemade electrolyte fix. I've tried a few but couldn't get past that salty taste. Strawberries seem to do the trick for me. Thanks!
Thank you! I actually prefer the super plain one that's made just with lemon/lime juice but only because it's quicker to make. This one is definitely tastier 😊
