Is Vitamin B12 Vegetarian?

Vitamin B12, also known as cobalamin, is a water-soluble vitamin that plays a vital role in producing red blood cells, maintaining nerve health, and synthesizing DNA. It is naturally found in significant amounts in animal products such as meat, dairy, and eggs. For vegetarians and vegans, fortified foods or supplements are often necessary sources, as plant-based foods do not naturally contain B12 unless they are fortified or fermented with B12-producing bacteria.
