Other Ingredients (8)

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.

CarmineColorant

Insect-derived (not vegan/vegetarian) and a recognized cause of IgE-mediated allergic reactions, including documented anaphylaxis. The FDA mandated explicit 'carmine'/'cochineal extract' labeling in 2011 specifically because of these reactions. Not toxic to the general population, but a genuine allergen with no health benefit; plant pigments achieve the same color.

Choline BitartrateNutrient Source

The bitartrate salt of choline, an essential nutrient.

MicaColorant

A naturally occurring silicate mineral used as a pearlescent colorant

Silicon DioxideAnti-caking

Fine silica powder used to prevent clumping

GelatinCapsule

Protein derived from collagen, used in traditional capsule shells

Vegetable OilCarrier

Edible oils used as carriers in softgels and as processing aids

GlycerinHumectant

Sweet-tasting liquid used in soft capsules and liquids
