What does Maltitol do?

Sugar alcohol used as a low-glycemic sweetener. Modest dental and blood sugar benefits; notable digestive side effects.

Can cause significant digestive upset (bloating, gas, diarrhea) especially at doses above 20-30g — a common issue with polyols that is rarely disclosed on product labels

Maltitol - Science-Based Research

What the Science Says

Maltitol is a sugar alcohol (polyol) used as a lower-calorie substitute for sugar in foods like candies, baked goods, and chewing gum. It produces a smaller blood sugar spike than regular sugar, making it a common ingredient in products marketed to people with diabetes or those watching their carbohydrate intake. Some research suggests that chewing gum containing maltitol may help reduce gum inflammation and plaque buildup compared to not chewing gum at all, though it appears less effective than xylitol for dental benefits.

What It Doesn't Do

Not a proven weight loss ingredient. Does not remineralize tooth enamel on its own — that claim is not supported by lab studies. Not as effective as xylitol for reducing cavity-causing bacteria. Not a free pass for people with diabetes — it still raises blood sugar, just less than regular sugar. Does not provide any meaningful nutritional benefit.

Absorption & Bioavailability

Moderate — partially absorbed in the small intestine; unabsorbed portion is fermented by gut bacteria, which is why it commonly causes digestive side effects like bloating and diarrhea at higher doses.

Red Flags to Watch For

Can cause significant digestive upset (bloating, gas, diarrhea) especially at doses above 20-30g — a common issue with polyols that is rarely disclosed on product labels
Still raises blood glucose and insulin — not truly 'sugar-free' in metabolic effect; people with diabetes should not assume it is safe in unlimited quantities
Products labeled 'sugar-free' or 'diabetic-friendly' often contain large amounts of maltitol, which can still impact blood sugar control
Dental benefits seen in studies were largely due to the mechanical act of chewing gum, not maltitol specifically — xylitol consistently outperforms maltitol in dental research
Safety data on mutagenicity and genotoxicity only recently evaluated (2023 EFSA request), suggesting long-term safety data gaps
