Description
HIGH-PURITY SPECIALTY INGREDIENT
Zinc L-Carnosine Powder 98%
Zinc L-carnosine is supplied as the zinc complex of L-carnosine at 98.0%, released against a batch-specific certificate of analysis. This is a complex rather than a mixture: the zinc content and the carnosine content are both fixed by the complex, and both figures belong on the specification. It is an industrial raw material for further processing and is not a finished consumer product.

Buyer Decision Guide
Agree the complex assay, the zinc content and the analytical methods for both figures before approval. Confirm whether the buyer’s process requires the pre-formed complex or separate zinc and carnosine additions, since the two approaches give different results and are not interchangeable.
- Complex assay: 98.0%, released against the batch COA.
- Zinc and carnosine contents both declared per batch.
- Confirmed as the pre-formed complex, not a blend.
- Particle size and packing agreed at quotation.
- COA, specification sheet and safety data sheet accompany each shipment.
- Regulatory status, permitted uses and labelling are the buyer’s responsibility for the destination market.
How This Grade Differs
Zinc L-carnosine is a defined complex, not a blend of zinc salt and carnosine. It also differs from plain L-carnosine, which contains no zinc. Because the zinc and carnosine contents are fixed by the complex, these are separate products and cannot be substituted on a weight-for-weight basis.
For a substitution review, compare botanical identity, plant part, assay target, analytical method, physical form and the current offered-batch COA.
