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.

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.

Medium Chain Triglyceride OilCarrier

Fractionated oils rich in C8/C10 triglycerides used as neutral carrier or anti-sticking agent

Polyvinyl AlcoholCoating

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

Silicon DioxideAnti-caking

Fine silica powder used to prevent clumping

Fruit Juice (unspecified)Colorant

Juice or juice concentrate used primarily for natural color and flavor in gummies

Ascorbic AcidAntioxidant

Vitamin C used as an antioxidant preservative in supplements to prevent oxidation
