Other Ingredients (12)
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.
LicoriceFlavor
Glycyrrhizin in whole licorice can cause pseudoaldosteronism at chronic/high intake — raised blood pressure, sodium retention, and hypokalemia (EFSA flags exposure limits). Deglycyrrhizinated (DGL) licorice avoids this, but a bare 'licorice' listing does not disclose which form.
DextroseSweetener
A simple glucose sugar used as a bulking agent, sweetener, and tablet diluent
Magnesium StearateLubricant
A salt of stearic acid used as a lubricant in tablet and capsule production
Natural Color (unspecified)Colorant
Umbrella declaration for a colorant from a natural source (fruit, vegetable, or plant extract) that the label does not name specifically
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.
Rose Hips (base)Botanical Base
Dried fruit of Rosa canina used as a whole-food base in vitamin C formulas; contributes trace natural vitamin C
Rutin (base)Botanical Base
Citrus/buckwheat bioflavonoid included in vitamin-C-complex tablet bases at non-therapeutic amounts
