Other Ingredients (35)

Artificial ColorsColorant

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

Titanium DioxideColorant

Banned in the EU (2022) over concerns that its ultra-fine particles may damage DNA in gut cells. Still allowed in the US. Used only for white coloring — provides no health 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.

Beta-Carotene (color)Color

Beta-carotene used in small amounts as a colorant/antioxidant.

BiotinFood

Vitamin B7, a water-soluble B-vitamin.

Folic AcidVitamin

Synthetic form of vitamin B9 used for fortification — supports red blood cell formation and neural tube development. Pharmacologically distinct from the natural/active form (5-methyltetrahydrofolate, methylfolate).
