Vitamin b 12 red blood cells production

 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.
