Ferrous Gluconate Granules Manufacturing: Process and Benefits

Ferrous gluconate granules are a highly effective iron supplement used to treat and prevent iron deficiency anemia. The manufacturing process ensures high bioavailability and stability, making it a preferred choice for pharmaceutical and nutraceutical applications.

Manufacturing Process of Ferrous Gluconate Granules

1. Raw Material Selection
High-purity ferrous gluconate powder is the primary ingredient. Additional excipients like binders, disintegrants, and stabilizers are used to enhance granule formation.

2. Granulation
– Wet Granulation: Ferrous gluconate is mixed with a liquid binder (e.g., PVP or HPMC) and passed through a granulator to form uniform granules.
– Dry Granulation: Used for moisture-sensitive formulations, where compaction and milling create granules without liquid binders.

3. Drying & Sizing
Wet granules are dried in a fluidized bed dryer to remove excess moisture. The dried granules are sieved to ensure consistent particle size.

4. Coating (Optional)
A protective coating may be applied to prevent oxidation and improve taste masking.

5. Quality Control & Packaging
Granules undergo rigorous testing for iron content, dissolution rate, and microbial limits before being packed in moisture-resistant containers.

Benefits of Ferrous Gluconate Granules
– High Bioavailability: Better absorption compared to other iron salts.
– Gentle on Stomach: Reduces gastrointestinal side effects.
– Versatile Applications: Used in tablets, capsules, and liquid formulations.
