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.
Blackstrap MolassesSweetener
High sugar content. High glycemic index. Can spike blood sugar. Used as a cheap filler — adds calories without meaningful supplemental benefit in typical amounts. May contain acrylamide from processing.
Wildflower HoneySweetener
A natural sweetener and humectant produced by bees, used in syrups and lozenges
Fruit Juice (unspecified)Colorant
Juice or juice concentrate used primarily for natural color and flavor in gummies
Silicon DioxideAnti-caking
