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
FD&C Red No. 40Color
Artificial azo dye; ADI-limited; associations with hyperactivity in sensitive children in some studies.
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
