Table of Contents
🥘Ingredients
You only need 5 ingredients to make a delicious lemonade without sugar.
- Lemon juice: Best to use lemon juice from fresh organic lemons.
- Lemon zest: Adds a nice hint of lemon to the lemonade.
- Allulose: A rare sugar that doesn’t raise blood sugars or insulin levels.
- Stevia Powder: An extra addition to the allulose to make it as sweet as sugar.
- Water: Just add water to your lemonade syrup for an easy lemonade!
Lemonade Sweeteners
Since allulose is only 70% as sweet as sugar, I personally like to do a mix of allulose and stevia (or monk fruit) so that it has the same sweetness as table sugar.
Since this low carb lemonade uses a homemade lemonade syrup, I don’t recommend using erythritol or xylitol as it tends to crystalize in the fridge once cooled. Allulose will not crystalize and will definitely give you the perfect consistency and sweetness.
🍋Fresh lemon vs lemon juice
Fresh lemons will definitely taste much better than bottled lemon juice so I definitely recommend using some fresh lemons if you have some. However, if you don’t, don’t worry just used your favorite bottled lemon juice!
If using fresh, make sure to use organic lemons and wash them thoroughly as we will be using the skin for the zest.
How to make lemonade🍋
To make homemade lemonade without sugar, you will first need to make the lemonade syrup which is essentially simple syrup mixed with lemon juice and lemon zest.
How many lemons needed?
For this recipe, you need 1 cup of lemon juice which equals to about 8 lemons.
Lemonade Syrup
This lemonade syrup recipe is incredibly simple. First you’ll want to add ⅓ cup of water into a small pot and add the allulose and stevia powder.
Put it on medium heat, stir a bit and wait until the allulose has fully dissolved. Once dissolved turn off the heat and add in the lemon juice and the zest of one lemon.
- Pro Tip！Freeze your lemonade syrup for later use if you don't want to use it all!
Lemonade Recipe for One
To make this homemade lemonade with my simple syrup, you’ll add a ¼ cup of lemonade syrup to a glass and add 1 cup of water to it and mix! And there you have it. One single serving of homemade lemonade. Super simple, right?
Half a Gallon Lemonade
If you want to make a pitcher of lemonade, add 2 cups of lemonade syrup and 8 cups of water to that. Add lots of ice to make it nice and cold.

How to Store Lemonade
In the fridge
The finished lemonade drink will stay fresh in the fridge for 7-10 days. The lemonade syrup recipe will stay fresh in the fridge for 2-3 weeks.
In the freezer
You can also freeze the lemonade syrup in small portions in the freezer.
Another idea is to freeze your homemade into some popsicle molds and have some delicious lemonade popsicles that you or your kids can enjoy!
👪Serving Suggestions for Toddlers and Kids
For Toddlers:
I personally don't give any sugar, maple syrup, honey or coconut sugar to my daughter so this is one drink that I give her a couple of sips of when I do make it.
I introduced stevia early on and allullose and erythritol around 10 months to her and checked that she didn't have any reactions. If your baby is fine with these sweeteners, then I suggest serving only a couple of tablespoons once in a while between the age of 1-3.
We usually drink water or tea in the house so we don't want her to get used to sweet drinks so this is a once in a while treat.
For Kids:
Serve a cup or more depending on how thirsty they are! Make sure they are okay with the sweeteners beforehand though so that they don't have any allergic reactions.

Roberta
Unfortunately, allulose is not allowed in EU yet... Would just stevia or monkruit pure extract powder, or a DIY blend of the two, be a decent substitute here if you aim to avoid a "crunchy" lemonade due to erytrhitol? Or maybe stevia glicerite drops? In so, what amount would you suggest?
Mira
Hi Roberta, I used to do a stevia only lemonade. 1000ml water, 5 tbsp lemon juice and 1/8 tsp stevia powder.
Barb
I have difficulty finding allulose, but managed to find some bocasweet - would that work as a suitable alternate?
Many thanks in advance!
Mira
Hi Bard, we don't have bocasweet in Japan so I've actually never tried it! If you do try, let me know if it works!
Marie
Oh wow, I always tried making some with erythritol and it just wasn't working out. This was really good.
