Sucralose

Sucralose is a zero-calorie artificial sweetener derived from sucrose, used to provide intense sweetness in sports drink powders and ready‑to‑drink mixes.

Background and science

Sucralose is made by chlorinating sucrose, replacing three hydroxyl groups with chlorine atoms. This modification makes the molecule roughly 600 times sweeter than table sugar and prevents it from being digested for energy As a result, sucralose passes through the digestive system largely unchanged and has no effect on blood glucose levels. Its sweetness intensity allows formulators to use tiny amounts to achieve a similar sweetness profile as sugar, keeping sports drinks low in calories while maintaining flavour. Sucralose is stable at high temperatures and across a wide pH range, which is why it is found in powdered mixes, gels and ready‑to‑drink products that sit in warm environments. Regulatory bodies around the world, including the FDA, have evaluated the safety of sucralose and set acceptable daily intake limits. Some individuals may notice a subtle aftertaste or digestive sensitivity when consumed in large amounts, so moderate use is advisable, but it remains one of the most researched sweeteners on the market.

Key properties and uses

High-intensity: about 600 times sweeter than sucrose; only tiny amounts are needed. Heat stable: does not break down during pasteurisation or storage in warm conditions. Non‑nutritive: provides negligible energy because the body . Because of these properties it is used to sweeten zero‑sugar sports drinks, tablets an gls. It may be blended with other sweeteners such as acesulfame potassium or stevia to round out the flavour and reduce any aftertaste. Athletes who are sensitive to sugar alcohols may prefer sucralose because it does not cause gastrointestinal distress at typical serving levels.

A wrap up: Sucralose allows manufacturers to provide sweet taste without adding carbohydrates, making it useful for low‑calorie hydration during training or for athletes monitoring sugar intake. Like any intense sweetener, it should be consumed in moderate amounts and balanced with whole‑food sources when possible.
