Product Overview
Ferrous Gluconate Powder is an organic iron salt commonly used as an iron source in dietary supplements, fortified foods, and nutritional premix systems.
It is usually supplied as yellow gray to greenish yellow powder, and buyers often review assay, elemental iron content, ferrous iron basis, heavy metals, microbial limits, solubility, color impact, and documentation scope before technical or commercial evaluation.
It is commonly considered for tablets, capsules, food fortification, and mineral premix applications, with sample supply and batch documentation available for sourcing reference.

Applications
Dietary Supplements
Used in tablets, capsules, and mineral supplement formulas where a defined iron source is required.
Food Fortification
Considered where iron enrichment is required and the formula can tolerate its color and taste impact.
Nutritional Premixes
Suitable for vitamin-mineral premixes and multi-mineral blend systems where blending uniformity is important.
Pharmaceutical / OTC Projects
Where local regulation and grade requirements allow, it may be reviewed for pharmaceutical or OTC iron projects.
How to Choose the Right Grade / Form
Supplement Grade
For supplements, choose ferrous gluconate with defined assay, elemental iron content, heavy metal limits, microbial limits, and document support.
Food Fortification Grade
For fortified foods, review color impact, taste profile, solubility, heavy metals, microbiological quality, and food-grade documentation.
Premix Grade
For dry premixes, particle size, flowability, bulk density, and blending uniformity should be checked together with assay and iron content.
Confirm Specification
Compare suppliers based on actual elemental iron contribution, iron form, assay basis, and destination-market requirements.
Technical & Formulation Notes
Technical Notes
Ferrous gluconate is selected when an organic iron source is required for supplement, food fortification, or premix applications.
For procurement review, buyers should confirm CAS number, assay basis, elemental iron level, ferrous iron identity, appearance, solubility, heavy metals, microbial limits, and destination-market compliance before order confirmation.
Manufacturing & Process
Commercial ferrous gluconate powder is typically produced through controlled reaction of a gluconate source with iron compounds, followed by purification, drying, milling or sieving, and packaging.
Batch consistency should be evaluated through appearance, identification, assay, elemental iron content, loss on drying, and microbiological testing according to the agreed specification.
Compatibility / Formulation Notes
For capsules and tablets, ferrous gluconate should be blended uniformly and tested for excipient compatibility, color impact, and finished-product stability.
For food fortification, evaluate taste, color, oxidation behavior, and interaction with vitamins, minerals, proteins, and organic acids.
For premix systems, particle size, flowability, bulk density, and segregation risk should be reviewed before large-scale production.
For iron formulas, compatibility with vitamin C, folate, B vitamins, calcium, zinc, and magnesium should be reviewed according to the final design.
Extended QC & Test Items
Extended quality review may include appearance, identification, assay, elemental iron content, ferric iron control where required, loss on drying, residue on ignition, heavy metals, arsenic, lead, cadmium, mercury, total plate count, yeast and mold, E. coli, and Salmonella.
