Vitamin B12, also called cobalamin, is found in foods from animals, such as red meat, fish, poultry, milk, yogurt, and eggs. In recent years, fortified cereals, breads, and other grain products have also become important dietary sources of B12 and folate (identified as folic acid on nutritional labels).
Some people will find they still need to supplement with a B complex vitaminâespecially vegetarians or vegans who consume no animal products, as animal products are the only natural source of B12. Good sources of B vitamins include: 1  Eggs. 2  Tuna. 3  Turkey. 4  Dairy products. 5  Dark, leafy greens (chard, kale, spinach, etc.).
