Other Ingredients (6)

FD&C Yellow No. 6Colorant

May trigger sensitivity in some individuals; behavioral concerns in susceptible children

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.

Citric AcidAcidulant

Natural acid derived from citrus fruits

Psyllium (seed/husk)Fiber

Natural soluble fiber from Plantago ovata seed husks, widely used as a fiber supplement base
