B12 injections have been used to treat anemia since the 1930′s. It wasn’t long after that people started using them to treat anemia that doctors discovered these shots had much wider uses – including reducing stress and fatigue, helping sleep patterns, supporting cognitive function, and boosting cardiovascular health.
These quick and effective nutrient injections are not just for the sick anymore. In fact, they are being widely used by some of the most successful and healthy people in the world to give them that extra edge. Many swear this is the pick-me-up they need to stay on top of their health and supplement their busy schedules and travels.
What is Vitamin B12?Vitamin B12 is a water-soluble vitamin that plays an important role in brain function and red blood cell production. It also plays a vital role in the growth and replication of cells as well as nervous system functioning.
Who is at Risk for Being Deficient?Vegans and Vegetarians: Up to 90% of people who follow a vegetarian or vegan diet are deficient in B12! This is because B12 is only found naturally in animal foods. The good news? You can supplement what you are not getting in your diet through a natural vitamin shot given intramuscularly.
- Meat Eaters: Don’t think just because you eat meat you are safe from being or becoming B12 deficient either! You may be surprised to know that it has been widely reported that almost 40% of Americans could be lacking appropriate levels of B12.
- Gastric Bypass Patients: People who have stomach stapling or another form of weight-loss surgery are very likely to be low in B12 because the operation interferes with the body’s ability to extract it from food. Bariatric patients are at an increased risk of developing B12 deficiency because in most adults without this surgery, B12 is broken down in the acidic environment of the stomach.
- Intrinsic factor: released by the parietal cells in the stomach—binds with B12 in the duodenum. The bound B12 is then absorbed in the ileum! In patients who have had gastric bypass surgery, most of the stomach and duodenum are bypassed, therefore limiting the breakdown of B12 and its subsequent binding with an intrinsic factor!
- Other People at Risk: Certain people with select absorption problems, intestinal issues, small intestinal bacterial overgrowth, ongoing inflammation processes, tapeworms, or history of tapeworms, and those with autoimmune disorders are also at risk of developing inadequate B12 levels. Unlike other vitamins, the absorption of B12 (as we discussed above) depends on a protein produced in your stomach, called the intrinsic factor. There are many other people with underlying health issues who do not produce enough intrinsic factors and can become deficient as well.
What are the Signs of Deficiency?It is important to note that many signs of low B12 levels are also symptoms of other medical conditions and if any or multiple of these symptoms are present, you should be evaluated by a medical professional. On the other hand, given the wide array of symptoms it can cause, the condition can be overlooked or confused with something else, oftentimes going misdiagnosed or underdiagnosed.
- Strange sensations, numbness, or tingling in the hands, legs, or feet
- Difficulty walking (staggering, balance problems)
- Swollen, inflamed tongue
- Difficulty thinking and reasoning or memory loss
Are B12 Injections Safe?B12 doesn’t build up toxicity like some other vitamins can when taken in excess. That means that it is extremely rare to see any negative side effects. This makes it a safe and effective health booster to consider adding to your wellness radar!
B12 shots are the most common way to prevent or treat a deficiency and are more effective than taking orally because of better absorption. The injections are prescribed by a medical professional and given into the muscle. There is no downtime and the entire process is very short!
Injections are usually given as hydroxocobalamin or Methylcobalamin which are effective at raising blood levels of B12 and preventing/reversing a deficiency.
