Product Overview
Polaprezinc is a unique, chelated compound consisting of Zinc and L-Carnosine in a 1:1 molar ratio. Unlike simple mixtures of zinc and carnosine, the chelated structure of SRBio Polaprezinc is designed to remain stable in the gastric environment, allowing for a gradual dissociation and targeted support where it is needed most.
Our Polaprezinc is manufactured to the highest purity standards, providing a crystalline powder that is ideal for premium dietary supplements focused on digestive wellness and long-term mucosal integrity.

Key Advantages
1. Superior Chelation Stability
SRBio Polaprezinc is a chemically bonded chelate, not a dry blend. This molecular stability ensures that the zinc and carnosine reach the target areas without premature dissociation, providing a more consistent performance in finished formulations compared to standard zinc salts.
2. Targeted Mucosal Support
The slow-release nature of the zinc-carnosine complex allows it to adhere to the gastric lining effectively. This targeted delivery supports the natural structural integrity of the digestive tract and promotes healthy cellular function without interfering with normal digestive acidity.
3. Optimized Bioavailability
By combining zinc with the dipeptide L-Carnosine, our Polaprezinc offers a gentle, highly bioavailable form of zinc. This reduces the risk of the “metallic aftertaste” or digestive nausea often associated with zinc gluconate or zinc sulfate.
Manufacturing Excellence
Advanced Crystallization Technology
We utilize a controlled crystallization process to ensure a uniform particle size and high bulk density. This makes the powder exceptionally easy to handle during high-speed encapsulation and tableting, reducing dust and improving flowability.
