Other Ingredients (9)

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.

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.

Citric AcidAcidulant

Natural acid derived from citrus fruits

GelatinCapsule

Protein derived from collagen, used in traditional capsule shells

Lactic AcidAcidulant

Naturally occurring organic acid used as a pH adjuster and preservative in supplements
