Aspartame is without a doubt the most common artificial sweetener on the market today, and as such, finding a tasty diet soda without aspartame can be a real struggle. So we decided to do the work so that you don’t have to.


Here’s a list of the best and most popular diet drinks without aspartame on the market in 2021:




Bai Bubbles the best diet soda without aspartame

The sleek design

Bai is a company that focuses on creating great tasting beverages with minimal additives. Founded in 2009 by Ben Weiss, their product line contains a wide selection of different flavoured low calorie diet drinks. All drinks are aspartame free and instead contain a sugar alcohol called Erythritol, as well as Stevia to provide the sweetness. While not completely free of calories, the drinks do boast a rather negligible 5 kcal per serving.

In addition, Bai uses ingredients such as coffeefruit which helps ensure that many remote and relatively poor regions are given greater economic opportunities, creating a better future for the hardworking farmers. Using coffeefruit in their drinks also helps to reduce botanical waste and helps to strengthen the land. Our top choice for an aspartame free soda!

Virgil is also proud to claim that their soda’s are officially Keto approved. So if that’s your concern, worry no more!

Green Cola - aspartame free diet drink

Green Cola

Green Cola was developed in 2012 by a Greek company called Green Cola Hellas. It’s been branded as the cola drink that tastes like other colas but without all the bad stuff.

The beverage contains no artificial additives or sugar, and is sweetened only with Stevia. The product has limited global availability, however Amazon does offer shipping to some parts of the world. It comes in various packages, from cans to plastic or glass bottles.

In addition to the flagship product, the company also offers extra juice flavours which contain a percentage of natural juice. Due to the natural sugars present, these drinks do however have a small caloric content.





RC Diet Cola

The Centennial

RC Cola was created in 1905 in Columbus, Georgia by Claud A. Hatcher, who would lead to create and lead the company. The same company that eventually developed Diet Rite, and is currently also owned by Dr Pepper Snapple Group Inc.

The name RC Cola stands for Royal Crown Cola, and was coined in 1934 when the formula was first improved. As the brand gained popularity, the consumers abbreviated it to RC Cola.

Their long standing diet version of the drink uses Sucralose for sweetness.






RC Cola products can be found all over the world in many different retail outlets. If you know of a good place where to get the diet version, let us know in the comments section!


#9 – *Removed

Previously held by Diet Pepsi, we have removed them from the list because as of 2019, Diet Pepsi once again contains Aspartame.

Pepsi has had a rather confusing love/hate relationship with the additive, so do let us know if the circumstances happen to change yet again. We know a lot of you were big fans of their aspartame free diet soda, so maybe they’ll switch things around yet again.

#10 – *Removed

Previously held by Diet Coke with Splenda, we’ve removed them from the list as they seem to have discontinued the product as of 2020. You may still find leftover supplies in some areas if you look, but seems like no more will be made.



Hopefully this list has helped you find your next favourite diet soda without aspartame in the mix!
