NMN is a naturally occurring biologically active nucleotide. There are two irregular forms of NMN, α and β; β isomer is the active form of NMN with a molecular weight of 334.221 g/mol. Because nicotinamide belongs to vitamin B3, NMN belongs to the category of vitamin B derivatives. It is widely involved in many biochemical reactions of the human body and is closely related to immunity and metabolism.

NMN is a nutrient substance that is converted into NAD+ in the cells. It is classified as a brand-new vitamin B3, and surpasses the efficacy of ordinary vitamins. It is considered as a supplement for preventing aging and restoring youth. NMN itself is a substance contained in the human body, present in breast milk and food, such as edamame, broccoli, cucumber, cabbage, avocado, tomato, etc., but the content is very small (0.25-1.88 mg per 100 grams). Raw beef and shrimp also contain very small amounts of NMN (0.06-0.42 mg per 100 grams). Therefore, if you want to improve NMN, you must directly supplement it from the outside world.

NMN is a substance naturally produced in humans and organisms. From the point of view that breast milk contains NMN, it can be said that it is one of the nutrients that humans first ingest after birth. Yellow-green vegetables also contain NMN, so unlike medicines, NMN is a natural source of food and is safe. However, the possibility of individual effects like food allergies cannot be ruled out.
