Product Overview

Ferrous Gluconate (E579) is a high-purity organic ferrous salt in yellowish-grey to pale greenish-yellow crystalline powder form. It is available in anhydrous and dihydrate forms, offered in food grade and pharmaceutical grade. Dihydrate grade is the most widely used commercial form with stable crystal structure and good oxidation resistance; anhydrous grade has higher iron content and no crystal water, intended for special low-moisture formulations. It is an organic chelated iron source with milder gastrointestinal irritation compared with inorganic iron salts such as ferrous sulfate. Widely used as organic iron fortifier, it is mainly applied in cereals, bakery, dairy products, plant-based milk and dietary supplement formulations, while also serving as mild pH regulator for food systems.

Character

1.Yellowish-grey to pale greenish-yellow crystalline powder, with a slight caramel-like odor and faint metallic taste that is milder than inorganic iron salts.

2.Readily soluble in warm water, forming a pale yellow-green solution; insoluble in ethanol.

3.Organic ferrous (Fe²⁺) form with good bioavailability, directly absorbable by the human body.

4.Milder gastrointestinal irritation compared to ferrous sulfate, reducing nausea, stomach discomfort and off-flavor in the mouth.

5.Dihydrate form is the conventional commercial grade with stable crystallization, easier handling and wider acceptance by food and supplement manufacturers.

6.Anhydrous form contains no crystal water, with higher iron content, but requires stricter moisture and oxygen control during storage.

7.Iron is prone to oxidation and color change under high pH, heat and long air exposure; formulation pH control and packaging protection are required.

8.Food grade and pharmaceutical grade comply with international standards for mineral fortification.

Main Functions

1.Iron Fortification Function: Provides bioavailable organic ferrous iron for mineral enrichment in cereals, bakery, dairy, plant-based milk and dietary supplement tablets, capsules and oral liquids.

2.Acidity Regulating Function: Acts as mild pH regulator to assist in stabilizing food systems during processing and shelf life.

3.Color Stability Auxiliary Function: Requires pH control and packaging protection to prevent undesired oxidation browning and discoloration of finished products.

Applications

Food & Dietary Supplement Industry: Ferrous Gluconate is mainly applied as an organic iron fortifier in breakfast cereals, bakery products, meal replacement powders, dairy drinks, plant-based milk, infant formula and other iron-enriched foods. It is also widely used as an iron source in dietary supplement tablets, capsules, oral liquids and powder sachets. Dihydrate grade is the mainstream choice for general food and supplement production, while anhydrous grade is selected for moisture-sensitive and high-end formulations. Its mild taste and better tolerance make it suitable for sensitive groups and long-term iron supplementation.

Pharmaceutical Industry : Pharmaceutical grade Ferrous Gluconate is used as iron source in oral iron supplements and therapeutic preparations with relatively low consumption.

Packaging & Storage

Packaging: 25kg food-grade paper bag / paper drum with inner PE waterproof liner

Storage Condition: Store in cool, dry, ventilated warehouse; keep tightly sealed. Protect from light, high humidity, direct sunlight and high temperature to prevent oxidation and agglomeration.

Iron is an essential heavy metal that is included in many over-the-counter multivitamin and mineral supplements and is used therapeutically in higher doses to treat or prevent iron deficiency anemia. When taken at the usual recommended daily allowance or in replacement doses, iron has little or no adverse effect on the liver. In high doses and in intentional or accidental overdoses, iron causes serious toxicities, one component of which is acute liver damage.

Soluble in water; practically insoluble in alcohol. Aqueous solutions are stabilized by addition of glucose. /Dihydrate/|Ferrous gluconate is affected by light and the ferrous iron slowly oxidizes to ferric on exposure to air.|Approximately neutral solutions undergo rapid oxidation; oxidation is retarded and stability improved by buffering to a pH of 3.5 to 4.5 with citrate buffer. Glycerin also retards oxidation.|Sugar, glycerin, & many organic hydroxy acids hinder precipitation. In neutral solution, soluble carbonates, phosphates, & oxalates produce precipitation. /Ferrous salts/

-------------------------------------Our Quality------------------------------------

Our Quality

As a professional ingredient supplier, we do not operate manufacturing facilities. Instead, we build robust quality‑assurance workflows across our whole supply chain to safeguard consistent product performance for every shipment

Strict Supplier Due‑Diligence

Before entering any partnership, we carry out on-site factory visits and assess industry reputation, followed by multi-stage qualification reviews. We validate production qualifications, export track records, quality management systems and complete certification packages. New suppliers must pass sample evaluation, and only fully vetted top-tier factories are admitted to our approved supplier pool

Batch‑by‑batch Document Verification

For every order, we cross‑check factory‑issued test documents against agreed specifications including FCC, USP, EP, AJI, CP or your customized requirements. We will not forward documents to customers until key indicators are fully aligned with specifications. This step avoids inconsistent or mismatched documentation common in raw‑material trade.

Independent Third‑party Testing Coordination

Upon client request, we can arrange independent laboratory inspections from recognized third‑party institutions. We manage sample delivery, test protocol communication and report follow‑up to support your market compliance needs.

Quality Closure & Continuous Improvement

We keep traceable records for all delivered batches. If any quality concern arises, we act as your single point‑of‑contact to trace root causes with source factories, drive corrective actions and deliver practical resolution plans. Client feedback is systematically collected to optimize our supplier management and document‑review procedures.

We provide a comprehensive set of compliance documents to support your import and registration work. Our available documentation includes but is not limited to:

★ ISO Certification ★ Halal Certificate
