Activating the source of youth is more than just fighting aging.
NAD+ is not only essential for maintaining life, but is also considered key to maintaining youth. Scientists have successfully reversed the physiological age of 2-year-old mice by supplementing them with NMN to increase NAD+, equivalent to a 60-year-old returning to their 20s.

NMN's effectiveness in protecting against toxins, radiation, and repairing DNA damage has also been recognized by NASA. NASA plans to use it to help astronauts protect against cosmic radiation and reduce cell mutations caused by DNA damage.
Located in the R&D center of Hong Kong Science Park, GeneHarbor (Hong Kong) Biotechnology Co., Ltd. has successfully developed a patented technology for the all-natural, green production of NMN, leveraging its world-leading biotechnology platform built over the past two decades. This technology transforms cutting-edge global scientific research results into products that everyone can enjoy, making "healthy longevity" readily accessible.
Improve bodily functions and alleviate symptoms of aging

NMN can combat functional decline at the cellular level, thus improving physical condition, promoting metabolism, building muscle and reducing fat, and improving sleep. Studies have also shown that it can delay various signs of aging and improve appearance, hearing, and vision loss. More and more related research is constantly discovering and verifying its increasingly beneficial effects.
