Other Ingredients (11)
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.
SorbitolSweetener
A FODMAP sugar alcohol that may trigger GI discomfort (bloating, gas) in individuals with IBS or sorbitol malabsorption, even at small amounts found in supplements. Avoided in low-FODMAP diets.
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 Cherry FlavorFlavor
