ADVANCED MINERAL CHELATION: ENHANCING BIOAVAILABILITY AND GASTROINTESTINAL TOLERANCE OF FERROUS BISGLYCINATE CHELATE THROUGH WBCIL'S FULLY REACTED MANUFACTURING STANDARDS

Ferrous Bisglycinate (FBG) chelate is a technologically advanced iron supplement designed to overcome the limitations of traditional iron salts like ferrous sulfate. Unlike standard ionic iron, Ferrous Bisglycinate is a fully reacted bidentate chelate—specifically manufactured by West Bengal Chemical Industries Ltd., Kolkata, India (WBCIL)—where ferrous iron is chemically sequestered within two glycine rings. This unique molecular architecture ensures high stability in gastric acid and prevents the release of free reactive ions, thereby eliminating common gastrointestinal side effects such as nausea and constipation. Clinical data demonstrates that this chelated form utilizes both the standard DMT1 pathway and the high- capacity PepT1 dipeptide channel, resulting in bioavailability 2 to 4 times higher than traditional salts. Studies across diverse populations, including pregnant women and pediatric patients, consistently show that lower elemental iron doses of Ferrous Bisglycinate (e.g., 25mg) are as effective as higher doses of ferrous sulfate (e.g., 50 mg) in managing iron deficiency anemia. By leveraging the advanced manufacturing standards of WBCIL, this chelate addresses the chronic issue of patient non- compliance and emerges as a gold-standard delivery system for sensitive populations requiring efficient and tolerable iron repletion.
