Benefits of Vitamin B12
Vitamin B12, an essential vitamin, is not produced by the body and must be obtained through diet or supplementation. Vitamin B12 is crucial for producing red blood cells and proper nerve, muscle, and brain function. Consuming a vegan or vegetarian diet, having stomach or gastrointestinal disorders, or being older than age 60 increases the risk of vitamin B12 deficiency. Restoring Vitamin B12 with Vitamin B12 injections can have the following benefits:
- Better Nerve and Muscle Function
- Clearer Cognitive Functioning
- Lower Risk of Anemia
- Improved Mood
- More Energy
- More Restful Sleep

Vitamin B12 FAQs
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:
- Improved memory
- Improved mood
- More energy
- Decrease in weakness and fatigue
- Improve the health of skin, hair, and nails
- Improved sleep
- May improve ringing in the ears
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:
- Fatigue
- Muscle weakness
- Nausea
- Trouble with balance
- Irritability
- Weight loss
- Numbness or tingling in the hands and feet
- Diarrhea
- Smooth and tender tongue
- Fast heart rate
Risk factors for Vitamin B12 deficiency include:
- Using antacids long-term
- Having pernicious anemia
- Having inflammatory bowel disease
- Having autoimmune disorders such as type 1 diabetes
- Taking high doses of folic acid
- Having lower stomach acid levels due to aging
- Taking metformin for more than four months
- Being vegan or vegetarian
- Using alcohol excessively
- Having a family history of Vitamin B12 deficiency
- Having part of your stomach or intestines removed
- Being older
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:
- Some medications slow Vitamin B12 absorption or increase Vitamin B12 use.
- Certain medication conditions make it harder for the body to absorb Vitamin B12
- Of limited dietary intake, especially in people who are vegan or vegetarian.
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.

What is Vitamin B12?
Vitamin B12 Deficiency is Common
Vitamin B12 is a water-soluble vitamin that is naturally found in some foods and added to others. Vitamin B12 supplements are available in both oral and injectable forms. Vitamin B12 deficiency is fairly common, affecting 6% to 23% of people under age 60 and nearly 20% of those over age 60. Malnutrition, vegetarian or vegan diet, gastritis, and alcohol misuse are contributing factors.
Vitamin B12 is Important in Carbohydrate and Lipid Metabolism and Red Blood Cell Function
Vitamin B12 is essential for growth, cellular reproduction, blood formation, neurological function, DNA, and protein synthesis, among other things. Vitamin B12 also aids in red blood cell production and metabolizing carbohydrates. Efficiently metabolizing carbohydrates and producing red blood cells that optimally carry oxygen to hardworking muscle and brain tissue boosts your overall energy and mental clarity.
Multiple Medical Conditions Are Associated with B12 Deficiency
Obesity, insulin resistance, dyslipidemia, and cardiovascular disease have all been linked to low Vitamin B12 levels. Vitamin B12 is involved in the regulation of DNA coding for proteins (epigenetics) as well as many metabolic processes in the cell. There is mounting evidence that Vitamin B12-DNA interactions regulate lipid metabolism and play a role in fat deposition.
How Does Vitamin B12 Work?
Absorbing Vitamin B12 is a Multi-Step Process
Vitamin B12 is an essential vitamin because it is obtained entirely through diet. Vitamin B12 is found in animal products and fortified foods in the diet, but it can also be taken as a supplement.
When bound to the food we eat, Vitamin B12 is released from protein by hydrochloric acid and an enzyme called gastric protease. When Vitamin B12 is added to food or taken as a supplement, it is already in a free form and does not need to be released. Once Vitamin B12 is free, it combines with intrinsic factor in the stomach.
Intrinsic factor is a glycoprotein secreted by specialized cells lining the stomach called parietal cells. The combined intrinsic factor Vitamin B12 is absorbed into the body in the ileum, which is the most distal part of the small intestine. Vitamin B12 then binds to transcobalamin, and the complex moves through the bloodstream. The complex is absorbed into cells. Approximately two years’ worth of Vitamin B12 is stored in the liver.
