Clams are the absolute highest source of vitamin B12, providing over 3,000% of the daily value in just 3 ounces. Other top sources include liver, salmon, beef, and fortified nutritional yeast.
Natural plant foods don't contain vitamin B12, so vegans need fortified foods or supplements. Reliable options include fortified plant milks, breakfast cereals, nutritional yeast, and meat substitutes that list B12 on the label.
Adults need 2.4 micrograms of vitamin B12 per day, with slightly higher amounts for pregnant women (2.6 mcg) and breastfeeding women (2.8 mcg). Most animal-based foods easily meet this requirement in small portions.
