B12 Fortification refers to the process of adding vitamin B12 to food products to help prevent deficiencies in populations that may not get enough from their diet. This is particularly important for individuals following a vegan or vegetarian diet, as B12 is primarily found in animal products. Fortified foods can include cereals, plant-based milk, and nutritional yeast. The goal of B12 fortification is to improve public health by ensuring adequate intake of this essential nutrient, which is crucial for nerve function, red blood cell production, and DNA synthesis. Regular consumption of fortified foods can help maintain optimal levels of vitamin B12 in the body.
