FAQ

A. Yes, all products are manufactured in factories located in Japan. We also conduct purity testing for NMN at accredited laboratories within Japan. For quality assurance, unopened samples of raw NMN are randomly and irregularly selected and sent to third-party testing institutions in Japan for purity analysis.
(Process: Unopened raw material → Sent to analysis institution → After testing, shipped directly to the factory → Factory sends samples for microbial testing → After passing, final delivery.)

A. As this is an OEM (contract manufacturing) service, the delivered products become your company’s own brand. You are free to determine the sales method and pricing. Label design is also up to you, except for legally required information such as ingredient listings and mandatory statements. Please provide your completed label design data as needed.

A. NMN (Nicotinamide Mononucleotide) is a compound derived from vitamin B₃, naturally present in all living organisms. Recent research has shown that activation of sirtuin genes (longevity genes) is linked to anti-aging. Sirtuin activation requires the coenzyme NAD⁺, but as we age, the body’s ability to produce NMN—the precursor of NAD⁺—declines. This decrease is believed to contribute to age-related changes in health and energy. Supplementing with NMN helps restore NAD⁺ levels, supporting cellular repair, metabolism, and youthful vitality.

A. The OEM service covers the following processes: • Capsule and container filling • Label application • Expiration date printing • Desiccant (silica gel) insertion • Shrink wrapping • External microbial testing (total viable bacteria, E. coli, coliforms)

A. We introduced small-lot production to lower the entry barriers for supplement brands and rapidly expand the NMN market. By offering flexible, low minimum order quantities, we make it easier for more companies to launch their own NMN products and participate in the growing market.
