Overview
Calcium fructoborate is a biologically active complex where boron is chelated with fructose and calcium. This unique molecular structure enhances bioavailability compared to inorganic boron compounds. The substance has gained attention in the nutraceutical industry for its potential health benefits, particularly in supporting bone and joint health. Originally developed as a more bioavailable form of boron, calcium fructoborate represents an advanced form of mineral nutrition. Its development addressed the challenge of poor absorption associated with traditional boron supplements while providing synergistic calcium delivery.
Physical and Chemical Properties
Calcium fructoborate appears as a fine white to slightly off-white powder with good solubility in water. The compound maintains stability under normal storage conditions but may degrade under extreme pH or high temperatures. Its molecular structure features boron atoms coordinated with fructose molecules and calcium ions in a stable complex. The compound's bioavailability stems from its organic nature, allowing for better absorption in the gastrointestinal tract compared to inorganic boron salts. Analytical characterization typically includes HPLC for purity assessment and atomic absorption spectroscopy for elemental composition verification.
Main Applications
The primary application of calcium fructoborate is in dietary supplements targeting bone health, joint support, and mineral nutrition. Formulators value it for its dual delivery of bioavailable boron and calcium, often incorporating it into capsule, tablet, or powder formulations. Beyond mainstream supplements, calcium fructoborate finds use in specialized medical foods and functional beverage applications. Some research suggests potential benefits in inflammatory response modulation, though these applications require further clinical validation for regulatory approval in various markets.
Safety and Storage
Calcium fructoborate is generally considered safe when used according to recommended guidelines. Typical dosage in supplements ranges from 100-300 mg daily. As with all boron-containing compounds, excessive intake should be avoided, with the upper limit for adult boron consumption generally set at 20 mg/day. Proper storage involves protection from moisture and extreme temperatures. The material should be kept in tightly sealed containers in a cool, dry environment away from direct sunlight. Shelf life typically ranges from 24-36 months when stored correctly.
B2B Procurement Guide
When sourcing calcium fructoborate, buyers should prioritize suppliers who can provide comprehensive documentation including certificates of analysis, stability data, and safety profiles. Pharmaceutical-grade material with purity ≥98% is recommended for supplement applications. Key procurement considerations include batch-to-batch consistency, residual solvent levels (where applicable), and microbial quality. Established suppliers in China and Europe typically offer competitive pricing, with minimum order quantities commonly starting at 25 kg for standard commercial purchases. Third-party testing verification is advisable for new supplier qualification.
