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. 'Natural' is a regulatory definition (21 CFR §101.22), not a safety guarantee.

Fine silica powder used to prevent clumping
Fruit Juice (unspecified)Colorant
Juice or juice concentrate used primarily for natural color and flavor in gummies

Take it anytime
