Other Ingredients (13)

Glucose SyrupSweetener

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

MaltodextrinBinder

Added sugars and high glycemic load; dental caries risk

Fruit Juice (unspecified)Colorant

Juice or juice concentrate used primarily for natural color and flavor in gummies

Natural FlavorsFlavor

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.
