Other Ingredients (6)
Artificial ColorsColorant
May trigger hyperactivity in sensitive children; potential link to allergic reactions
AspartameSweetener
Classified by IARC as Group 2B (possibly carcinogenic to humans) in July 2023 based on limited evidence of hepatocellular carcinoma. JECFA simultaneously reaffirmed the 40 mg/kg/day ADI as safe. MANDATORY FDA WARNING: contains phenylalanine — contraindicated in phenylketonuria (PKU). Anecdotal headache/migraine reports in sensitive individuals are documented but mechanism is unclear. The additive is purely cosmetic — risk:benefit unfavorable for any supplement.
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.
Artificial FlavorsFlavor
Composition is proprietary and not disclosed on the label, so allergens or solvents cannot be verified. Naturally flavored alternatives are more transparent.
Silicon DioxideAnti-caking
Fine silica powder used to prevent clumping
Citric AcidAcidulant
Natural acid derived from citrus fruits
