Added sugars and high glycemic load; dental caries risk
Glucose SyrupSweetener
High glycemic load; source typically corn (generally gluten-free)

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.
