A Certificate of Analysis (COA) is a laboratory-issued document confirming that a product was tested against defined specifications. For NMN, it should report ingredient identity, purity or assay, heavy metals, microbiology, and other relevant contaminants. Without a COA, label claims cannot be objectively verified.

A generic COA may have no connection to the batch you are buying, while an outdated COA may not represent the current product. A raw-material COA is also distinct from a finished-product COA. The strongest evidence is current, batch-specific, issued by an independent laboratory, and complete across identity, purity, heavy metals, and microbiology.

Traceability connects the product in your hand to the documentation behind it. Novera links each product to its batch number, COA, ingredient technical data sheet, Japanese Certificate of Free Sale, and applicable GMP, Vegan, Kosher, and Halal certifications. This is verifiable quality documentation, not a medical claim.

Japan is widely recognized for precision manufacturing, disciplined quality control, and robust documentation standards for exported products. This does not make every Japanese product inherently superior. It means the country’s manufacturing and regulatory framework can support a high degree of documentation, traceability, and consistency.

A Certificate of Free Sale is a document issued by the competent authority in the country of origin confirming that a product is legally marketed and may be exported under the applicable regulatory framework. It is not proof of medical effectiveness. It is a regulatory and commercial document supporting the product’s legitimacy in its country of origin.

GMP, or Good Manufacturing Practices, is a system of standards governing production processes to support consistency, hygiene, process control, documentation, and quality systems. GMP does not prove that a supplement is effective. It demonstrates that the product was manufactured under controlled and documented conditions.

Supplements may contain trace amounts of contaminants such as lead, arsenic, cadmium, and mercury originating from raw materials or manufacturing processes. A product that claims high NMN purity but does not test for heavy metals cannot document its control over these contaminants. Heavy-metal testing is an additional layer of safety and quality control, not a medical claim.

Kosher certification indicates that the product has been reviewed and approved under Jewish dietary-law standards. Beyond its religious significance, certification involves an additional review of ingredients, production processes, and handling. For many consumers, it also represents greater transparency and control throughout the production chain.

Halal certification indicates that the product complies with applicable standards for ingredients, production processes, and handling. It involves a review of the supply chain and is relevant to consumers who require Halal-compliant products. It may also provide additional information about ingredient sourcing and handling.

HPMC, or Hydroxypropyl Methylcellulose, capsules are plant-based capsules made without animal gelatin. They are a vegan alternative to traditional gelatin capsules and are relevant for vegan and vegetarian consumers or anyone seeking to avoid animal-derived ingredients.
