Animal-based foods are the most significant sources of vitamin B12. Here are some key examples:
| Food | Vitamin B12 Content (per 100g) |
|---|---|
| Clams | 98.9 mcg |
| Beef Liver | 70.7 mcg |
| Fish (Trout, Salmon) | 4.5 mcg |
| Fortified Breakfast Cereals | 6.0 mcg |
| Dairy Products (Milk, Yogurt) | 0.5 – 1.0 mcg |
| Poultry (Chicken, Turkey) | 0.3 mcg |
As seen in this table, clams and beef liver are among the best sources of vitamin B12. Just a small serving can provide more than the daily recommended intake.
Meat and Poultry
Red meats, such as beef and lamb, are also excellent sources of vitamin B12. Poultry, particularly turkey and chicken, contain lower amounts but still contribute to your daily intake. These foods are versatile and can be incorporated into a range of dishes.
Dairy and Eggs
Dairy products, including milk, yogurt, and cheese, are rich in vitamin B12. Eggs, while not as rich as other sources, can still help bolster your intake, especially if you consume them regularly.
