introduction
Ferrous Gluconate Powder is a highly bioavailable organic iron salt formed by combining ferrous ions (Fe²⁺) with gluconic acid, specifically developed to deliver superior absorption and gastrointestinal tolerance compared to conventional iron sources such as ferrous sulfate or ferrous fumarate.
Designed for B2B partners, this ingredient is ideal for dietary supplements, functional foods, and pharmaceutical formulations requiring reliable iron fortification for energy support, cognitive function, and healthy red blood cell production. Its organic chelate structure facilitates efficient intestinal absorption while being gentle on the digestive tract, significantly reducing the risk of common side effects like gastric irritation and constipation. With an assay of 97.0%–102.0% and an iron content of approximately 12.0%, it exhibits excellent flow properties, good water solubility, and a mild, non‑metallic taste – making it suitable for tablets, capsules, powders, gummies, syrups, and oral solutions. Recommended usage typically ranges from 15–30mg elemental iron per serving, depending on target demographics and regional regulatory limits.
All backed by LANDNUTRA – with ISO, GMP, Halal, and Kosher certifications, full traceability, COA, stability data, and regulatory support to accelerate your product development and global market entry.
