Added sugars and high glycemic load; dental caries risk
Tapioca SyrupSweetener
High glycemic index similar to glucose syrup. Adds significant sugars and calories — often the primary ingredient by weight in gummy supplements. 'Organic' labeling does not change the glycemic impact.

Fruit Juice (unspecified)Colorant
Juice or juice concentrate used primarily for natural color and flavor in gummies
Natural FlavorsFlavor
Broad regulatory category of flavor constituents derived from natural sources. 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.
Turmeric ColorColorant
Natural yellow colorant from the rhizome of Curcuma longa; the pigment is curcumin
Citric AcidAcidulant
Natural acid derived from citrus fruits
GelatinCapsule
