Other Ingredients (13)

Artificial ColorsColorant

May trigger hyperactivity in sensitive children; potential link to allergic reactions

FD&C Yellow No. 6Colorant

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

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.

FD&C Red No. 40Color

Artificial azo dye; ADI-limited; associations with hyperactivity in sensitive children in some studies.

SucroseSweetener

Added sugars and high glycemic load; dental caries risk

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.

Carnauba WaxCoating

Hard plant wax from the carnauba palm used to glaze gummies and tablets

How to Take It

Take it anytime

No evidence a formula this broad works better at any particular hour. Take it with a meal containing fat — the vitamins A, D and E in it absorb poorly without one.

With a meal containing fat
Space it a couple of hours from Iron and Calcium

On the label

Adults: Fully chew two gummies daily.

General guidance based on the ingredients, not a substitute for the label or your doctor.
