B-12 and You: What You Need to Know

Do you find yourself feeling drowsy, fatigued, or lethargic? These symptoms could stem from a variety of conditions. However, if you’ve crossed all the other possibilities off your list, you might be deficient in vitamin B-12.

Vitamin B12

Vitamin B-12 is a vitamin that is water-soluble (meaning it does not get stored in your organs or tissues) and plays an essential role in many functions in the human body. Not only does vitamin B-12 assist in the formation of red blood cells and energy production, but it also has an important role in neurological function. Vitamin B-12 enters the body through food consumption. The vitamin is present in animal-based food sources, where it is bound to the protein molecules in that food. During digestion, B-12 separates from the protein molecules and is absorbed into the bloodstream.

As previously mentioned, B-12 plays a very integral role in a lot of key functions relating to overall health. Some individuals might be at risk for a deficiency, and there are others who cannot properly absorb the vitamin. Certain risk factors for a B-12 deficiency include but are not limited to alcohol abuse, smoking, and certain prescription medications. On top of this, aging adults, vegans and vegetarians, and individuals with gastrointestinal issues are more likely to lack the necessary amount of the vitamin.


If you fall into one of the above categories or fear you might not properly be absorbing enough vitamin B-12, there are some signs for you to be aware of. Common signs of B-12 deficiency include poor memory, fatigue, constipation, lethargy, feeling faint, depression or irritability, difficulty maintaining balance, and headache. Many of these signs can be attributed to other reasons, but if you experience more than one of these symptoms, lack of vitamin B-12 in your body could be a possibility.
Luckily, there is still a way to get sufficient vitamin B-12 into your body. Vitamin B-12 shots are injections containing high levels of cyanocobalamin. These shots, which are usually administered by a doctor or nurse, quickly boost B-12 levels in someone who is deficient. There are oral supplements but these methods aren’t nearly as effective as injections.

Besides the obvious reason for B-12 injections for people with a deficiency, there are other health benefits also. B-12 shots can help reduce the risk of heart disease, dementia, peripheral neuropathy, and vision loss. B-12 injections will also help individuals feel more energetic and improve overall health.
