Other Ingredients (9)
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.
Silicon DioxideAnti-caking
Fine silica powder used to prevent clumping
PectinGelling Agent
Plant polysaccharide from citrus peels or apple pomace used to gel pectin-based gummies
Calcium CarbonateBuffer
Common calcium salt used as a buffering agent, filler, or mineral fortification in supplements
Citric AcidAcidulant
Natural acid derived from citrus fruits
StarchBinder
Carbohydrate polymer used as a binder, filler, and disintegrant in tablets and capsules
