Vitamin B12 is one of the eight B vitamins and is essential for good health. It helps the body to produce energy, maintain the nervous system, and produce red blood cells. In addition, Vitamin B12 is important for maintaining the health of the myelin sheath, a protective covering that surrounds nerve fibers in the body.
Vitamin B12 is not produced by the human body, so it must be obtained from the diet or from supplements. Some good food sources of Vitamin B12 include meat, fish, poultry, eggs, dairy products, and fortified foods such as certain breakfast cereals and plant-based milk alternatives. People who follow a vegetarian or vegan diet may need to take a Vitamin B12 supplement, as B12 is not naturally present in plant-based foods.
What is a Vitamin B12 Deficiency?
A Vitamin B12 deficiency can result in a range of symptoms and health problems, including anemia, fatigue, memory loss, and numbness or tingling in the extremities. Vitamin B12 deficiencies can also cause nerve damage and, if left untreated, can lead to more serious health problems. People who are at risk of Vitamin B12 deficiency include the elderly, vegetarians and vegans, people who have had weight loss surgery, and those who have gastrointestinal problems that affect the absorption of B12.
It’s important to talk to your doctor if you think you may be at risk of a Vitamin B12 deficiency, or if you are considering taking a Vitamin B12 supplement. In most cases, a Vitamin B12 deficiency can be treated with supplements, diet changes, or injections. With proper treatment, the symptoms of Vitamin B12 deficiency can be reversed, and long-term health problems can be prevented.
