Sucralose Vs Aspartame

When it comes to comparing sucralose and aspartame, people often wonder if both sugar substitutes cause similar side effects. Overall, both are non-nutritive sweeteners. A sweet taste is imparted to food by both sweeteners, but they don’t contain any calories. This is the reason that they are often used in food as substitutes to sugar. It has been suggested by studies that there are certain distinct side effects that are caused by them. However, some of these side effects are actually caused by both artificial sweeteners.

Allergy or Sensitivity

There are many users who seem to be far more allergic or sensitive to aspartame or sucralose, than others and thus, they often experience far greater severe reactions by using these sweeteners. Abdominal pain, anxiety, bladder problems, dizziness, flushing, numbness and rashes are some of the symptoms that users might suffer from when using any of them. They might be able to get rid of these basic side effects by shifting to aspartame if they are using sucralose and vice versa.

Gastrointestinal Upset

Using them has often caused users to suffer from gastrointestinal problems. A variety of symptoms of gastrointestinal symptoms like bloating, diarrhea, gas and nausea are caused by both artificial sweeteners.


As per research studies, headaches in certain individuals seem to be triggered by both of them. Separate studies have noted that migraines headaches in users are triggered by both of these artificial sweeteners. Thus, certain people, whether they are using aspartame or sucralose, can experience migraine headaches. Removing either of these sweeteners from the diet for a couple of days is the only way of getting rid of these unexplained headaches. If the headaches stop once these sweeteners are no longer being used, then these symptoms were certainly being caused by them.

Increased Cravings for Sweets

According to studies, the desire for sweet food increases depending on the amount of sweet food that is consumed. Most people presume that this only applies to honey or table sugar, and they believe that using non-caloric sweeteners will not increase their cravings for sweets; however, the opposite happens. Using aspartame or sucralose causes users to crave for sweet flavors and sweet food to a great extent. In comparison to users who are consuming table sugar or honey, those who consume one of these non-nutritive sweeteners have complained increased sugar cravings. It has been suggested by researchers that artificial sweeteners such as aspartame and sucralose are far sweeter than table sugar, thus, this is the reason that the desire for sweet flavors is significantly increased when using them.

Overall, both of them are quite distinct artificial sweeteners, and they have their own individual qualities and traits. The chemical composition and the taste of these sweeteners vary; however, there are also certain similarities such as the fact that they contain no calories. Most importantly, when comparing sucralose to aspartame, a considerable similarity between the side effects these sweeteners cause, has been noticed.
