Other Ingredients (8)
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.
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
Magnesium StearateLubricant
A salt of stearic acid used as a lubricant in tablet and capsule production
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
Stearic AcidLubricant
Saturated fatty acid used as tablet lubricant
