Manufacturing process can leave 1,4-dioxane (probable carcinogen) and ethylene oxide as contaminants. Look for 'vacuum-stripped' products.
Chelating agent — generally tolerated but documented MCAS trigger in case reports.
Weakly oestrogenic preservatives. Endocrine concerns particularly relevant for hormonal conditions.
Each ingredient on this product's published label is matched against our 237 source-cited chemical rules, each documenting a concern from peer-reviewed research and regulatory sources. Severity tiers:
Each flag links to its primary chemical-level source, and each condition pill links to a PubMed-indexed paper that discusses the chemical class in the context of that condition. Every citation is a real peer-reviewed paper — we don't link to Wikipedia or PubMed search pages. Some pairs use a topically-broad paper (e.g. a fragrance-allergen patch-test review) rather than a single-pair study where the literature is thin. The full evidence chain (chemical → mechanism → condition → paper) is one click away.
This is automated analysis of a published label, not medical advice — always verify the label yourself before changing products. Methodology and source list at scan.lowtoxgear.com.
