Other Ingredients (10)
FructoseSweetener
Added free fructose is metabolized in the liver and at habitual intake is linked to elevated triglycerides, hepatic fat accumulation, and insulin resistance; an avoidable sugar load with no supplement benefit.
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.
Natural Cherry FlavorFlavor
A flavoring derived from natural cherry sources
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.
Silicon DioxideAnti-caking
Fine silica powder used to prevent clumping
Beetroot Juice PowderColorant
Natural red colorant and mild flavoring derived from beetroot; often spray-dried onto maltodextrin carrier
Citric AcidAcidulant
Natural acid derived from citrus fruits
