Isomaltulose (also marketed under the trademark Palatinose™) is a naturally sourced disaccharide of glucose and fructose, produced from sucrose through an enzymatic rearrangement of the glycosidic bond. Where sucrose links its two sugars by an α-1,2 bond, isomaltulose is joined by a more stable α-1,6 bond — the small structural change that gives it a uniquely low glycaemic index (GI of 32 vs. sucrose GI of 65) and a completely different metabolic profile. The raw material is sucrose derived from sugar beet, making isomaltulose a naturally sourced, non-GMO carbohydrate.
Because that α-1,6 bond is hydrolysed 4–5 times more slowly than sucrose, isomaltulose is digested gradually along the full length of the small intestine. It is fully digestible and delivers the same 4 kcal/g as sugar, but releases glucose into the bloodstream slowly and steadily — providing sustained energy over roughly four hours without the sharp glycaemic spike of conventional sugars. This makes it a preferred sugar replacer for sports nutrition, diabetic-friendly products, functional foods and hydration beverages.
Slow-release, sustained energy
Isomaltulose is a low-glycaemic, slow-release carbohydrate. Its steady glucose delivery avoids the peak-and-crash cycle of fast sugars and supports a more balanced insulin response — the basis for its use in endurance and sustained-energy formulations. Lower blood glucose and insulin responses have been confirmed in more than 30 human trials, in subjects ranging from healthy adults and children to overweight, obese and glucose-intolerant individuals (including type 1 and type 2 diabetes).
Weight management & fat burning
By keeping insulin lower through slower glucose release, isomaltulose promotes fat oxidation (fat burning) rather than fat storage. In a 12-week randomised, double-blind study in overweight and obese adults, replacing sucrose with isomaltulose in an energy-reduced diet significantly reduced caloric intake, increased fat burning, and led to greater body-weight and body-fat loss. Separate intervention studies in Asian middle-aged and elderly adults reported less visceral (abdominal) fat accumulation.
Healthier blood glucose management
Slow, low glucose release also drives a favourable gut-hormone response, promoting GLP-1 secretion — a hormone associated with improved insulin release, increased satiety and better blood-glucose control. Low-GI diets are supported by international scientific consensus (ICQC) as beneficial for reducing blood glucose levels and the risk of diabetes and heart disease.
Cardiovascular health
In studies where sedentary or older adults replaced high-GI carbohydrates with isomaltulose, researchers observed preserved insulin sensitivity, lower daylong glucose and insulin levels, and reduced markers of arterial stiffness and endothelial dysfunction — pointing to a supportive role in long-term metabolic and cardiovascular health.
Enhanced hydration
Isomaltulose is stable at low pH and helps a beverage maintain its isotonicity over time, while its gradual, sodium-dependent absorption supports steadier fluid uptake and better fluid retention. In controlled human studies, isomaltulose-based electrolyte drinks improved the Beverage Hydration Index by around 25% versus rapidly absorbed carbohydrates, with lower urine output and maintained plasma volume — valuable for sports, functional and everyday hydration products.
Tooth-friendly
Isomaltulose is non-cariogenic (tooth-friendly), as it is not readily fermented by oral bacteria into acids that damage tooth enamel.
