A vitamin B12 shot plays a key role in the normal functioning of the brain and nervous system, and in the formation of healthy blood cells. Although most people get enough B12 from a healthy diet, some individuals have difficulty absorbing this essential nutrient. Longterm B12 deficiency can damage the nervous system, and even less severe cases still result in a range of unpleasant symptoms including tiredness, weakness, constipation, loss of appetite, weight loss, problems with balance, depression, poor memory, and soreness of the mouth or tongue. Indeed, sufficient levels are important to keep your body running in top condition. Therefore, supplements are available to assist people with B12 deficiency. What are the benefits of a B12 shot? Vitamin B12 shots are most commonly prescribed to prevent a deficiency or treat a deficiency in people who have an impaired ability to absorb this crucial nutrient. The injection contains about 500 times more vitamin B12 than the recommended daily dose. Injecting B12 allows the vitamin to be delivered directly to the bloodstream so that it is easily absorbed by the body. B12 plays an essential role in cell metabolism, and many injection recipients report increased energy levels and better memory and concentration. Should I get the B12 shot with my flu shot? Yes! Vitamin B12 injections give you added energy to keep you feeling your best during flu season, when your body may be particularly run down. Higher levels of vitamins, including B12, in the body’s tissues have been shown to increase antibody production by the immune system following flu shots. Are you a candidate for B12 injection?
