Vitamin B12 injections can replenish Vitamin B12 in people who are deficient. Low Vitamin B12 levels are more common in people over the age of 65, those with gastrointestinal problems, strict vegetarians, and those who have had bariatric surgery. There is some evidence that supplemental Vitamin B12 can improve mood even in people without a true Vitamin B12 deficiency.
Restoring Vitamin B12 levels can provide the following benefits:
The effects of a Vitamin B12 injection can be felt within about 48 to 72 hours. People who are not deficient in Vitamin B12 are not likely to notice any benefits. How fast Vitamin B12 is metabolized in the body will also vary by person but is expected to be less than one week.
Vitamin B12 affects numerous bodily functions, including the production of red blood cells and brain functions. Symptoms of low Vitamin B12 include:
Risk factors for Vitamin B12 deficiency include:
If you are Vitamin B12-deficient, a Vitamin B12 injection is expected to have effects within 48 to 72 hours. Depending on your metabolism and the severity of your Vitamin B12 deficiency, you may notice improvements in your energy levels in as little as two to three days, but it may take weeks of treatment to feel the full effects.
Vitamin B12 deficiency and insufficiency are relatively common because:
Unlike other vitamins, Vitamin B12 requires intrinsic factor, a substance produced in the stomach to aid in Vitamin B12 absorption. In those with low stomach acidity (a condition associated with aging), a lack of intrinsic factor can lead to a lack of Vitamin B12.
Inflammatory bowel disease and other bowel conditions, having surgery on the stomach or intestines, or even the bacterial flora composition in your intestines can affect Vitamin B12 absorption.
Vitamin B12 is a water-soluble vitamin. Since excess Vitamin B12 can be excreted in the urine, even high doses are generally considered to be safe. There is no set “tolerable upper limit” for Vitamin B12 because it has such a low potential for toxicity and the body does not store excess amounts. The recommended daily intake (RDI) of Vitamin B12 is 2.4 mcg for both men and women.
