CautionSometimes. Vitamin B12 can come from either animal products or bacteria cultures. If the label does not provide a source, we recommend calling the manufacturer.
Vitamin B12 and the Vegetarian Diet
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.
