Vitamin B12, also known as cobalamin, is an essential nutrient that your body needs but cannot produce. It's found naturally in animal products but also added to certain foods and available as an oral supplement or injection. Vitamin B12 has many roles in your body. It supports the normal function of nerve cells and is needed for red blood cell formation and DNA synthesis.
B12 may benefit your body in impressive ways, such as by boosting your energy, improving your memory, and helping prevent heart disease. B12 is also associated with improving mood and symptoms of depression.
For those looking for natural sources of B12, foods such as beef liver, clams, fish, meat, poultry, eggs, milk, and other dairy products can be excellent sources. For vegetarians and vegans, fortified cereals, plant-based milk, and nutritional yeast can be incorporated into meals to attain the necessary B12 intake.
Despite its importance, there's plenty of misunderstanding about this vital nutrient and its impacts on our health. Let's dive deeper into understanding B12, its benefits, uses, and food sources.
