introduction
Ferrous Gluconate Liquid is a clear, greenish‑to‑brown aqueous solution of iron(II) gluconate, widely used in oral iron supplements, liquid multivitamin preparations, and fortified beverages. It offers superior bioavailability, mild organoleptic properties (minimal metallic aftertaste), and excellent stability in liquid formulations, making it an ideal choice for functional foods, pharmaceuticals, and nutraceuticals. With a controlled iron content of 11.6‑12.5% and full compliance with USP/BP/EP standards, this liquid form provides consistent dosing, easy blending, and reduced gastrointestinal irritation compared to inorganic iron salts – key advantages for manufacturers targeting sensitive consumer groups such as children, pregnant women, and the elderly.
LANDNUTRA, with over 20 years of manufacturing expertise, ISO international certifications, and a service network covering more than 130 countries and regions worldwide, is committed to providing B‑end customers with high‑quality ferrous gluconate liquids and tailored technical support – from customised concentrations and packaging to full documentation (COA, MSDS, stability, and heavy metal/microbiological reports). We also offer flexible MOQs, free lab samples, and dedicated R&D assistance, making us your trusted functional ingredient partner for liquid iron solutions.
