B12, also known as cobalamin, is a part of the B-complex family of vitamins that assist the body in vital functions. While B12 is present in some foods, it may be beneficial to get this important nutrient in the form of B12 injections. Learn why this is advantageous over other forms of intake.
What Is Vitamin B12?
B12 is a water-soluble vitamin mainly found in meat and dairy products. This vitamin plays a critical role in our bodily processes, such as:
- Releasing energy from the food we eat into our muscles
- Maintaining nervous system function
- Red blood cell production
Furthermore, B12 deficiency has been linked to a number of maladies. One study linked B12 deficiency to canker sores and mouth ulcers. Research also found a correlation between depression and low B12 levels.
The Problem with B12 Administered Orally
Why are injections necessary when B12 is readily available in some foods and in supplement form? There are two main reasons: bioavailability and quality of B12 products.
Various factors may affect the oral bioavailability (absorption rate) of B12. Excess caffeine and alcohol intake, for example, may adversely impact bioavailability. The same goes for medication use. Genetic factors may also affect absorption.
2. Supplements May Not Provide High-quality B12
Most B12 supplements contain a synthetic version of the vitamin known as cyanocobalamin. Some studies found that the body expelled cyanocobalamin through urination at three times the rate than methylcobalamin, the natural B12 variant found in foods. This suggests that the body may have difficulty retaining B12 in its synthetic form, though it will vary from person to person.
How Long Does It Take for B12 Injections to Take Effect?
Most people feel the effects of B12 injections within 24 hours. Unlike oral administration, injections enter directly into your bloodstream without going through a lengthy journey in your digestive tract.
4 Advantages of B12 Injections
B12 Injections may be beneficial for anyone diagnosed with B12 deficiency. Consider some of these advantages.
1. More Energy Levels
B12 regulates energy regulation in your cells. Studies have also linked B12 deficiency to lethargy and fatigue. Those who receive a B12 booster in the form of injections have noted more alertness and vigor.
2. Increase Metabolism Naturally
A huge variable that affects your ability to lose weight is your metabolism. The faster your metabolism, the more calories you burn. Various factors can slow or speed up your metabolic rate. Studies have linked B12 deficiency with low metabolism. With this in mind, B12 injections may be a helpful supplement as part of a consistent diet and exercise plan.
3. Help You Sleep at Night
Studies have also linked B12 to melatonin production. Melatonin is the natural sleep hormone that helps regulate your biological sleep clock. If you’re having trouble falling and staying asleep, B12 injections may provide a natural remedy.
4. Protect Your Heart
B12 minimizes homocysteine levels in your body. This amino acid produces platelets in the blood vessels that harden in the arteries. Excess homocysteine leads to an arterial blockage that can be detrimental to heart health.
