- Product Description
High-Purity Ferrous Bisglycinate Powder | Clinically Proven Bioavailability for Pharmaceutical Applications
Ferrous Bisglycinate Powder represents the most advanced chelated iron technology available to pharmaceutical companies. This is because it is used to develop effective and well-tolerated drugs for treating anemia. Shaanxi Hongda utilizes its core "all-aqueous phase chelation + constant temperature spray drying" technology, ensuring our product has a chelation rate greater than 95.0%, 3-4 times the utilization rate of ordinary iron, and guaranteeing no precipitation or oxidation in liquid formulations. We offer not only mineral raw materials, but also the ultimate solution for iron supplementation in "sensitive populations."
Shaanxi Hongda's pharmaceutical-grade ferrous glycinate formula contains 18-20% iron, and through specific technology, the body's absorption and utilization rate of iron is 2-4 times higher than that of ordinary iron salts. This gentle chelated iron is healthier than ordinary ferrous sulfate or ferrous fumarate because it causes minimal gastrointestinal problems. Your formulation has been practically tested and complies with all global regulatory standards, giving it a competitive edge. Its clinical efficacy has been verified and it complies with relevant regulations worldwide.

Why Choose Our Ferrous Bisglycinate Powder?
If you're developing an iron supplement, you're well aware of the challenge: balancing efficacy and tolerability. Our ferrous glycinate powder effectively addresses this challenge. Our chelated iron is suitable for both medications and dietary supplements, easily digested and absorbed, with absorption rates 2-3 times higher than traditional salts. Whether you're preparing a prescription anemia medication or an over-the-counter multivitamin, this powder can be mixed into tablets, capsules, or liquids. Our ferrous glycinate is clinically tested and approved for use in all global markets—that's what makes it so effective.
Key Benefits You Can’t Ignore
- Extremely high bioavailability and gut affinity: Ferrous glycinate does not prematurely dissociate in the stomach, thus avoiding nausea and constipation caused by oxidative stress, and improving gut comfort feedback from users by 70%.
- Exclusive flavor shielding and stability technology: HTC utilizes microencapsulation technology to ensure the raw material maintains a neutral flavor upon entering the mouth, making it particularly suitable for developing iron drops, gummies, and solid beverages.
- Anti-interference capability for complex formulations: Our fully chelated ferrous glycinate exhibits extreme stability in multi-dimensional formulations, without causing browning or degradation of active ingredients.
- Absorption You Can Trust: Clinically shown to outperform ferrous sulfate and fumarate.
- Zero Gut Drama: Minimizes nausea and constipation—common complaints with other iron types.
- Play Well with Others: Stable in formulations with vitamins, minerals, or botanicals.
- Globally Compliant: Meets USP, EP, and JP standards right out of the drum.

Superior Product Benefits That Revolutionize Iron Therapy
Chelated iron technology makes treatments perform better by making iron more accessible in a manner that ordinary iron salts can't. Ferrous Bisglycinate Powder chelation protects iron from substances in the digestive system that may get in the way and makes it simpler for iron to flow through the membranes of the intestines. Lower dosages help your patients' haemoglobin levels return to normal faster, which minimises the risk of adverse effects and makes it simpler for them to persist with their medication.
They are easy to create, so they may be put to tablets, capsules, and liquids without any trouble. The fine white powder stays chemically pure for the whole time it is on the shelf, and it is quite stable when it is handled in different ways. Your production teams benefit from consistent particle size distribution and reliable flow characteristics during manufacturing.
The main issue with iron therapy compliance is that some people may find it difficult to cope with. Clinical investigations reveal that these have far less cases of nausea, diarrhoea, and stomach issues than ordinary iron salts. Your prescribing physicians will have greater confidence in your capacity to adhere to treatment regimens and achieve desired outcomes.
Pharmaceutical Applications Across Therapeutic Categories
Prescription iron supplements for anemia treatment benefit from the superior absorption profile and enhanced patient tolerance. Prenatal and postnatal multivitamins leverage the gentle chelated form for sensitive populations requiring higher iron intake. Pediatric iron therapies utilize the improved palatability and reduced side effect profile for better compliance in young patients.
Over-the-counter drugs that include iron perform better at therapeutic dosages because they are more bioavailable. Folate, vitamin B12, and vitamin C act together in combination foods to totally cure anaemia. Geriatric formulations address absorption challenges common in elderly populations through the chelated delivery system.
Specialty applications include iron replacement therapy for chronic kidney disease patients and sports nutrition supplements for athletes with increased iron requirements. The pharmaceutical-grade quality supports prescription drug development while maintaining cost-effectiveness for OTC applications.
Provides complete "chelation strength" identification reports:
We offer more than just iron content data. For high-end clients, we provide Fourier Transform Infrared (FTIR) spectroscopy identification, proving that iron ions and glycine have formed genuine chemical bonds, rather than simply physical mixing.

Global Compliance Full Slam:
We hold complete system certifications including FSSC22000, KOSHER, HALAL, and ISO22000. We comply with the latest international food additive safety standards.

Customized Physical Index Optimization:
For high-speed tableting needs, we can customize particle size specifications, completely eliminating dust contamination and significantly improving filling accuracy.

Your Questions—Answered
Q: How can you show your product is fully chelated and not just ferrous sulfate and glycine?
A: FTIR spectroscopy detects peak shifts. Fully chelated goods have fingerprint-like chelate bond properties and are stable in aqueous solutions without phytic acid precipitation.
Q: Does 20% iron signify low purity?
A ferrous glycine molecule has a theoretical peak iron concentration of 20%. Inorganic iron salts are likely introduced if the amount is substantially greater. Active chelated iron, not elemental, is our goal.
Q: Does this powder oxidize and discolor during storage?
A: We employ light- and moisture-proof double-layer vacuum packaging. Our stable chelated structure won't oxidize, discolor, or clump in 24 months at constant temperature and dry circumstances.
Q: Ferrous Bisglycinate Powder reduces stomach troubles how?
A: Glycine coating protects gut lining from free iron ions. Science, not magic!
Q: Can I add vitamin C or folate?
A: Yes, we stability-tested combos. Request our compatibility guide.
Q: What's the MOQ?
A: 100kg initially, but we'll work with your R&D on smaller trials.
Q: How fast can you ship?
A: 10-15 days after docs approval. Need it yesterday? Our logistics team has rush options.
