Premium Zinc Bisglycinate by SRBio – High‑Absorption Chelated Zinc
SRBio Zinc Bisglycinate is a high‑purity, fully chelated mineral complex formed by bonding elemental zinc with glycine molecules. This chelated structure mimics natural organic mineral complexes in food, significantly improving absorption while reducing digestive discomfort.
Unlike inorganic zinc sources (zinc oxide, zinc sulfate), our bisglycinate form requires minimal stomach acid for uptake, making it suitable for daily long‑term use. It delivers consistent, well‑tolerated zinc nutrition for people of all ages and digestive conditions.
Uncompromising Quality & Manufacturing Excellence
Strict Purity & Safety Control
- Dual‑system testing ensures accurate chelation ratio, stable potency and batch‑to‑batch consistency.
- Heavy metal limits (ICP‑MS tested): As <0.5 ppm, Pb <0.1 ppm, Cd <0.05 ppm, Hg ND.
- Microbiological standards: Total plate count <1000 CFU/g; yeast & mold <100 CFU/g; E. coli, Salmonella, Staphylococcus aureus negative.
- Free from impurities, residues, and undeclared additives.
Advanced Water‑Based Chelation Process
- Controlled aqueous reaction without harmful organic solvents, eco‑friendly and safe.
- Multi‑stage crystallization and purification remove unreacted materials.
- Low‑temperature vacuum drying preserves molecular stability and solubility.
- Precision milling and sieving ensure uniform particle size and excellent flowability.
Outstanding Stability
- Stable for 24 months at 25°C/60% RH with no discoloration or potency loss.
- Low hygroscopicity to prevent caking during storage and processing.
- Protective nitrogen‑flushed packaging with desiccant for long‑term stability.
