a water-soluble vitamin crucial for human nutrition, essential for nerve function, DNA synthesis, and red blood cell formation
Vitamin B12, also known as cobalamin, is a water-soluble vitamin that plays a crucial role in many bodily functions. It is important for the production of red blood cells, which carry oxygen throughout the body, and for maintaining healthy nerve cells. Vitamin B12 is also involved in DNA production and supports normal brain function. Good dietary sources of vitamin B12 include meat, fish, poultry, eggs, dairy products, and fortified cereals. However, vitamin B12 is primarily found in animal products, so vegetarians and vegans may need to supplement their diet to ensure enough intake.
