NMN, which stands for β-nicotinamide mononucleotide, can be synthesized naturally in cells and derived from various foods. After entering the human body, NMN can be rapidly converted into NAD+, a substance that can enhance energy generation, damage repair, metabolism, tissue regeneration, etc., thereby achieving anti-aging effects and health enhancement. Due to such magic effect, NMN health supplements are also known as "elixir of youth".
