Other Ingredients (8)
MaltitolSweetener
Worst GI tolerance of the common sugar alcohols — laxative effect at doses above ~10–15 g/serving in many adults; threshold is lower in children. Glycemic index (~52) is significantly higher than erythritol (0) or xylitol (~7) — meaningful blood glucose impact at typical serving sizes. The 'sugar-free' marketing claim masks real metabolic effects when consumed in quantity.

Composition is proprietary and not disclosed — 'Natural Flavors' can include several hundred different compounds depending on the target flavor profile, including hexane-extracted constituents and proprietary carrier solvents. 'Natural' is a regulatory definition (21 CFR §101.22), not a safety guarantee.
