Vitamin B12 benefits your body in many ways. One of its key functions is to help your body in the creation of red blood cells. These cells help carry oxygen to your vital organs, including your heart and brain. This oxygen is crucial in providing you the necessary energy to get through each day. B12 also helps with white cell production, which is vital to keeping your immune system strong, which in turn keeps you healthy.
Vitamin B12 is vital in properly maintaining your nervous system and helping to keep nerve cells healthy. This in turn keeps your brain functioning the way it should. B vitamins also assist in the production and regulation of DNA, which is present in every cell in your body. And since this nutrient is also a very strong antioxidant, it helps fight off free radicals which can lead to cancer. It helps metabolize the food you eat so you can utilize it for energy. It does this by helping turn the carbohydrates in your food to glucose. Many people who struggle with fatigue and low energy have a vitamin B12 deficiency.
