Chromium picolinate and cinnamon bark tablets

This is a finished, film-coated tablet, not a bulk powder. The mineral carrier is chromium(III) picolinate, C18H12CrN3O6, MW 418.30, CAS 14639-25-9 (PubChem CID 151932) — a pinkish-red, poorly water-soluble tris-chelate of picolinic acid whose theoretical chromium content is 12.4% (Cr 51.996 divided by MW 418.30). Chromium is an essential trace element; the US Daily Value for adults and children four years and older is 35 µg, and tablet strengths are set against that figure rather than against the weight of the salt. Chromium(III) chloride (CrCl3, MW 158.35, CID 24808) and nicotinate-bound grades are quoted where a customer's dossier already specifies them. The botanical half is dried inner bark of Cinnamomum cassia (L.) J.Presl, Lauraceae — Chinese cassia, an evergreen Lauraceae tree of southern China now grown across South and South-East Asia. Coumarin is the commercial control point on any cassia article: published bark figures run 1.74–7.67 mg/g for cassia against only 0.005–0.090 mg/g for Cinnamomum verum, Ceylon cinnamon, and the German BfR tolerable daily intake is 0.1 mg coumarin per kg body weight. Every lot is assayed for coumarin (C9H6O2, MW 146.14) and the figure is declared, so your regulatory team can do the arithmetic on a full daily dose before the tablet is registered. Where a destination market restricts coumarin, we build the same tablet on Ceylon bark or on a coumarin-limited cassia fraction. Compliance points that decide whether a buyer can ship: only trivalent chromium is used and the oxidation state of the source salt appears on the certificate; the tablet is vegan, vegetarian and non-GMO with no milk, egg, soy, fish, crustacean, gluten, sesame, peanut or tree-nut input; and cassia is a tree bark, so it must never be declared as a tree nut. Thovek makes no therapeutic or disease claim for this article. Regulation (EU) No 432/2012 does carry two authorised nutrient-function claims for trivalent chromium, both conditional on the product qualifying as at least a "source of" chromium under Regulation (EC) No 1924/2006 — using them, and meeting that threshold, is the brand owner's responsibility in each market.
