This is a great way to make healthcare more accessible, especially for individuals who may find it difficult to visit clinics or hospitals Vitamin B12 is an essential nutrient that helps keep your brain, nerves, and blood cells healthy. It plays a big role in making red blood cells, which carry oxygen around your body. Vitamin B12 also helps in the production of DNA, the genetic material in your cells. Your body can't make B12 on its own, so you need to get it from food or supplements. Foods rich in B12 include meat, fish, eggs, and dairy products. Vegetarians or people who don’t eat these foods may need to take a B12 supplement or eat fortified foods (foods that have added B12). A lack of vitamin B12 can cause tiredness, weakness, memory problems, and even nerve damage over time.
