Vitamin B12 is essential for nerve function, red blood cell production, and DNA synthesis.
Foods rich in vitamin B12 include animal-based sources such as meat, poultry, fish (like salmon and tuna),
dairy products (milk, cheese, and yogurt), and eggs. Fortified cereals,
plant-based milks, and nutritional yeast are good alternatives for those following a vegetarian or vegan diet.
Ensuring adequate intake of these foods helps prevent deficiencies and supports overall health.
