Other Ingredients (16)

BHTPreservative

Potential carcinogen in animal studies; may affect thyroid function; restricted in some countries

Blue 2 LakeColorant

A synthetic coal-tar/petroleum-derived dye used purely for color, linked to behavioral concerns in sensitive children. The lake form adds aluminum. No health benefit — we flag all artificial colors.

TalcAnti-caking

IARC classifies cosmetic-grade talc not containing asbestos as Group 2B (possibly carcinogenic to humans); perineal talc use as Group 2A (probably carcinogenic). Johnson & Johnson voluntarily withdrew talc-based baby powder from US/Canada in 2020 and globally in 2022 after extensive litigation tied to ovarian-cancer and mesothelioma cases. The 2018 FDA contamination survey found asbestos in 9 of 52 cosmetic talc products tested. As a supplement excipient talc is a pure manufacturing convenience — no nutritional or functional benefit to the user — so the asbestos-exposure risk has no offsetting upside. Safer alternatives (silicon dioxide, microcrystalline cellulose, rice hulls) are widely available.

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.

FD&C Yellow No. 6Colorant

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

Magnesium StearateLubricant

A salt of stearic acid used as a lubricant in tablet and capsule production

Polyethylene Glycol (Coating)Coating

A polyether polymer used as a tablet coating and plasticizer

Polyvinyl AlcoholCoating

Synthetic, water-soluble polymer used as a film former and binder in immediate-release tablet coatings
