Vitamin B12, crucial for nerve function and red blood cell formation, is mainly found in animal products. Rich sources include meats like beef, pork, and lamb, along with poultry such as chicken and turkey. Fatty fish like salmon, tuna, and mackerel, as well as shellfish like clams and oysters, are excellent sources. Dairy products, including milk, cheese, and yogurt, also provide B12. For those following a vegetarian or vegan diet, fortified foods like plant-based milk, breakfast cereals, and nutritional yeast can offer B12. Supplementation may be necessary for those at risk of deficiency. Consult with a healthcare professional for personalized advice.
