How Soon Do B12 Injections Work?

If you have a B12 deficiency, you are always feeling tired, asleep, and with no energy. Some patients even have trouble recalling things. In simple words, you feel sick. 

B12 is a vitamin that keeps the nervous system and blood cells healthy. It’s critical to prevent megaloblastic anemia, responsible for feeling fatigued, weak, and tired. 

Even though many foods have vitamin B12, the best way to prevent a deficiency is by having a shot. B12 injections are the fastest and most successful form of absorption. 

Oral supplements of vitamin B12 must be digested before they can be delivered throughout the body. Contrary, B12 shots avoid the digestive process. A B12 injection goes straight into the bloodstream. That’s why when you’re diagnosed with a B12 deficiency, your doctor prescribed B12 injections to improve the condition faster. 

How Does It work?

A B12 injection has a dose of 1,000 micrograms which is placed into the muscle. Usually, your doctor will recommend a shot every three days for 90 days. If you have a severe B12 deficiency, you might need to continue the injections every month. 

It’s essential to notice that every patient is different, and results can vary. Some individuals see an improvement within a few days, but others have a much slower process. 

On average, you can expect to see results within 48-72 hours after the injection. B12 injections will effectively increase red blood cells while boosting your energy levels. 

Be patient as B12 deficiency is not easy to reverse. But once you inject B12 regularly, you’ll experience a new life.

Side Effects

Vitamin B12 shots are safe for most patients, and they don’t have any adverse side effects. In some exceptional cases, some individuals can suffer side effects caused by an allergic reaction or sensitivity. 

It’s essential to know that you don’t need to worry about having a vitamin B12 overdose since large quantities of this nutrient don’t cause any adverse symptoms. 

Please note that many prescription drugs can interfere with the body’s ability to absorb B12. Talk with your doctor to determine if you need to raise your consumption of vitamin B12.
