CAS: 68-19-9 INCI: Cyanocobalamin Vitamin B12, also known as cyanocobalamin, plays a vital role in many of the body’s important functions. It is essential for the proper formation of red blood cells, the proper functioning of the nervous system, and the production of DNA. It can be found in a variety of foods, including meat, fish, and dairy products. Vegetarians and vegans may have a higher risk of deficiency, as vitamin B12 is found primarily in animal-based foods. Those who are at risk of deficiency, such as the elderly, people with absorption issues or those who follow a vegan diet may benefit from taking supplements. Vitamin B12 is also important for maintaining the health of the skin, hair, and eyes.
