Other ingredients

SucroseSweetener

Added sugars and high glycemic load; dental caries risk

Glucose SyrupSweetener

High glycemic load; source typically corn (generally gluten-free)

MaltodextrinBinder

Spikes blood sugar faster than table sugar (glycemic index 85–105). Research links it to gut bacteria changes that may promote intestinal inflammation (Nickerson et al. 2015). Used as a cheap filler — adds nothing beneficial.

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.
