In short, yes! Feel free to keep reading if you’re interested to learn more.
Sucralose is everywhere, from diet sodas and protein shakes to flavored waters (including some of ours at Aquablu). But scroll through the headlines and you’ll see a split picture: some claim it’s perfectly safe, others suggest possible risks.
So what’s the truth? Let’s take a closer look at the latest research, how regulators view sucralose, and how it stacks up against other sweeteners.
What Sucralose Actually Is
Sucralose starts its life as ordinary sugar. In a multi-step process, three parts of the sugar molecule (hydroxyl groups) are replaced with chlorine atoms. This small chemical swap makes a big difference:
Calorie-free – the body doesn’t metabolize it for energy.
Heat stable – it keeps its sweetness in hot drinks and cooking.
Sugar-like taste – preferred by many consumers over other sweeteners that can taste bitter or metallic.
It’s 600 times sweeter than sugar, which means only a tiny amount is needed to sweeten drinks.
Is Sucralose Safe?
Sucralose is one of the most extensively studied sweeteners in the world, and it’s approved by leading food safety bodies, including:
The U.S. Food and Drug Administration (FDA)
The European Food Safety Authority (EFSA)
The World Health Organization (WHO)
Key scientific findings:
No evidence of cancer or genetic risks: Large-scale reviews have found no link between sucralose and cancer or genotoxicity (Magnuson et al., 2017).
No effect on blood sugar or insulin: Clinical studies show sucralose does not raise blood glucose or insulin levels, making it suitable for people with diabetes (Grotz et al., 2017).
Safe daily intake: The Acceptable Daily Intake (ADI) is 5 mg/kg body weight/day, a level rarely reached in normal consumption.
Why Do Concerns Keep Coming Up?
So why the confusion if regulators are so clear?
High-dose studies: Many headlines come from animal studies using extreme doses far above what humans consume.
The “chlorine” factor: Chlorine sounds alarming, but in sucralose it’s tightly bound in the molecule (similar to how sodium and chlorine combine harmlessly to form table salt).
Distrust of “artificial”: The word itself can raise skepticism, even when the science shows safety.
Sucralose vs. Other Sweeteners
Sucralose isn’t the only sugar substitute. Here’s how it compares:
Stevia: Plant-based, safe, and calorie-free. However, it can have a bitter or herbal aftertaste that not everyone enjoys.
Aspartame: Widely used, but not heat-stable and not suitable for people with PKU. It’s been more controversial in public perception despite ongoing regulatory approval.
Acesulfame-K (Ace-K): Often blended with other sweeteners, but can taste metallic on its own.
Sugar alcohols (xylitol, erythritol): Lower-calorie, but often linked to digestive discomfort in large amounts.
Compared with these, sucralose stands out for its clean, sugar-like taste, heat stability, and robust safety record. That’s why it’s become a go-to in many flavored waters and zero-sugar sodas.

The Bottom Line
The latest science and decades of safety reviews agree: sucralose is safe when consumed within recommended limits. It doesn’t raise blood sugar, hasn’t been linked to cancer, and is approved by every major food safety authority worldwide.
At Aquablu, our approach is simple: transparency first. We use sucralose in certain flavors because it delivers the taste our customers enjoy, without sugar, and with a safety profile we trust. If you’d rather avoid it, that’s always your choice. But the science is clear: sucralose is a safe alternative to sugar, and one we’re proud to stand behind.
