Vitamin B12 is an important nutrient that helps the body make red blood cells, support the nervous system, and maintain healthy cell function. It is one of the essential B vitamins, meaning the body needs it but cannot make enough of it on its own.
Most people get vitamin B12 from foods such as meat, fish, eggs, milk, and fortified foods. Others may need supplements or prescription B12 products when their body does not get enough or cannot absorb it properly.
Why vitamin B12 matters
One of the most important uses of vitamin B12 is helping the body form healthy red blood cells. When B12 levels are too low, the body may have trouble making normal red blood cells, which can contribute to anemia. This may leave a person feeling tired, weak, lightheaded, or short of breath.
B12 also supports nerve health. Low levels may sometimes be linked with numbness, tingling, balance issues, or memory-related concerns. Because these symptoms can have many causes, it is important to speak with a healthcare professional before trying to self-treat.
Who may need B12 support?
B12 is especially important for older adults, people who follow vegan or strict vegetarian diets, people with certain stomach or intestinal conditions, and patients taking medications that may affect B12 absorption. For example, long-term use of metformin or acid-reducing medications may increase the risk of low B12 in some people.
Vitamin B12 is available in several forms, including oral tablets, sublingual products, nasal products, and injections. Prescription injectable B12, such as cyanocobalamin injection, may be used when a healthcare provider determines that supplementation is needed.
