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.
Polysorbate 80Emulsifier
Chassaing et al. 2015 (Nature, PMID 25731162) tested polysorbate 80 directly and showed it thinned the gut mucus barrier, altered microbiota composition, and induced low-grade inflammation and metabolic syndrome in mice. The strongest human evidence is for a related emulsifier rather than polysorbate 80 itself: Chassaing 2022 (Gastroenterology, PMID 34774538) was a controlled human feeding RCT of carboxymethylcellulose (CMC) that found microbial encroachment into the mucus layer — polysorbate 80 has not been tested in an equivalent human trial. In vitro work (e.g. Roberts 2010) shows polysorbate 80 enhances bacterial translocation across intestinal epithelium, and observational data link overall dietary-emulsifier exposure to IBD risk. EFSA is mid re-evaluation of polysorbates (E432–E436). For a supplement excipient with purely cosmetic function (improving the look/texture of soft gels and liquids), the gut-barrier risk profile is unfavorable when safer alternatives (sunflower lecithin, MCT carriers, gum acacia) 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.
MonoglyceridesEmulsifier
Glycerol monoesters of fatty acids used as emulsifiers and processing lubricants
How to Take It
Take it anytime
No evidence a formula this broad works better at any particular hour. Take it with a meal containing fat — the vitamins A, D, E and K in it absorb poorly without one.
With a meal containing fat
Keep it away from high-oxalate foods like spinach
Space it a couple of hours from Iron
On the label
As a dietary supplement, adults take one (1) tablet daily with any meal or as directed by a healthcare provider.
General guidance based on the ingredients, not a substitute for the label or your doctor.
