SucroseSweetener

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.

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.

Citric AcidAcidulant

Natural acid derived from citrus fruits

PectinGelling Agent

Plant polysaccharide from citrus peels or apple pomace used to gel pectin-based gummies

Purified WaterSolvent

Water meeting USP specifications used as solvent/vehicle in gummies and liquids
