Vitamin B12 is a vital ingredient needed by the body for performing various tasks. Vitamin B12 is responsible for building DNA as well as for producing red blood corpuscles. It is a major source of nutrients, required for healthy functioning of the body. It is rightly called 'energy vitamin' since, it provides a real energy boost for the body. It is an instant remedy for fatigue, as it accelerates the rate of metabolism. Vitamin B12 injections are apparently useful in reducing weight.
Vitamin B12 Injections for Weight Loss
The main sources of vitamin B12 are meat, poultry, milk, eggs and fish. Naturally, those who follow a strict vegetarian diet have to rely on vitamin supplements. There are several people who opt for vitamin B12 injections as a cure for obesity. Vitamin B12 shots are directly injected into the muscles for better absorption. People who choose them, often have a history of chronic fatigue syndrome or a vitamin B12 deficiency. There are many reasons why vitamin B12 works for them.
How Vitamin B12 Injections Help to Reduce Weight
These injections do not reduce weight directly by themselves. There are several factors which contribute to weight loss along with vitamin B12. People who opt for vitamin B12 shots are likely to be on a vegetarian diet with an extra consciousness about their weight. Hence, there is more probability that these people also watch their diet and follow a strict exercise regimen. Vitamin B12 simply speeds up their metabolism and provides them with an unlimited supply of energy. This added vigor helps them to exercise for a long time, on a regular basis, without getting tired. It also motivates them to follow their diet more religiously. All this collectively results in weight loss.
As mentioned before, it is unlikely that vitamin B12 injections induce weight loss by themselves. It only replenishes the supply of vitamin B12 in the body. This vitamin B12 can be easily gained from your diet itself. The basic mechanism for reducing weight remains the same. Vitamin B12 rich diet acts as a metabolism booster, allowing more calories to be burned. The more the calories burnt, the less is the storage of fat. This ultimately results in weight loss.
Vitamin B12 injections do not come cheap, you need to shell around $65 for a single shot, which is a pretty expensive affair. Besides, you may have to pay around $200 towards initial consultation. The fact is, you can get the same benefits by simply making little alterations to your daily diet, and that too at far lesser expense. Moreover, vitamin B12 injections are helpful to only those people who have a deficiency of vitamin B12. Although, excess vitamin B12 does not necessarily cause any harm, there is no need to take it externally, considering its high cost.
Side Effects
Vitamin B12 injections are capable of inducing certain unpleasant effects. Most people show mild to severe side effects after being administered vitamin B12 shots. The common side effects include:
  • Mild diarrhea
  • Upset stomach
  • Nausea
  • A feeling of pain and a warm sensation in the area where the shot was administered
  • A swelling sensation throughout the entire body
  • Headache
  • Joint pain
Apart from these, some serious side effects like rapid heart rate, palpitation, excessive coughing or wheezing, chest pain etc. may also occur in rare cases.
If you decide to go for vitamin B12 injections, it is recommended that you consider all the pros and cons before administering it. Always opt for it as a last resort, when your diet or exercise cease to work. Otherwise, changes in your diet and self motivation for exercising can work far better than vitamin B12 shots in the long run and that too without any side effects.
