Only around 1% of patients develop a vitamin B12 deficiency after weight loss surgery (Roux en Y bypass), but it is advisable to take a B complex vitamin after this surgery since some other B vitamins might be at risk. Most patients will respond to B vitamins by mouth, however in a case that a severe deficiency develops, primary care doctor is allowed to give its patient a B12 shots which increases patient’s body’s stores for a few months.

Natural Foods VS B12 Shots for Weight Loss


We always seek for quick results when trying to lose weight, and that is why our bad habits eliminate the natural laws of life including natural cycles of the human body, digestion, and diet.

The fast food industry is one of the results of being convenient and saving time, yet it is pretty unhealthy for us. Microwaves are also the result of this reasoning, and they too are unhealthy. Boxed and canned dinners are also in this category, designed to make extremely big profits for large companies. They aren’t concerned with our well-being. When we interfere with the body’s and life’s natural cycles, the real problems occur. Eventually, the human body will respond with disease and ailments.

People reach for B12 shots because they are a shortcut just like steroids. All of this will affect your body in a negative way. A whole body needs whole solutions, not just parts of the solution which these supplements like B12 injections are. Have you ever wondered how you cannot overdose on vitamin B from food, but you can from these supplements? Most people don’t know that these B12 shots contain and include preservatives which do damage to the human body over time which leads to many problems later. We should ask ourselves if this is really worth the risk.

The best way to get your required daily dose of B12 is with natural food sources. Professionals say that supplements such as lipotropic injections promising quick weight loss usually fall short. Taking fewer calories than usually, exercising more often, and focusing on healthy foods is the ideal approach for anyone trying to lose weight.

Lipotropic injections (B12 shots) for Weight Loss: does it work?

You have probably heard that lipotropic injections might help you lose weight. It is true that some weight loss programs include B12 shots in their regimen, however there is no clear evidence that these injections will help you lose weight.

These weight loss programs claim that the B12 injections give us more energy as well as increase our metabolism, and in this way help us lose weight by being able to exercise more.

However, if you don’t have a B12 deficiency, taking extra vitamin B12 in any form – injection, pill, patch, nasal spray, or sublingual lozenge – won’t help in increasing your energy level.

Therefore, lipotropic injections won’t cause weight loss. Vitamin B12 shots will help contribute to your weight loss though because they help metabolize fat and protein. When fat and protein are metabolized, it produces extra energy, and more energy means it will be easier for us to lose weight.

It is true that B12 injections help metabolize protein and fat but not in big enough quantities where they actually cause weight loss. Nutritionist, doctors and scientists say that the loss in weight incurred by people receiving vitamin B12 supplements and B12 injections is because of the fact that these people are more active and eating healthier since they are trying to lose some weight, and not because of their increased intake of vitamin B12.

Here are a couple of reasons why B12 injections don’t work for weight loss:

First of all, vitamin B12 is water – soluble. Your body needs about 3 micrograms of this vitamin daily. B12 shots often have hundreds of percentages more than what the human body needs. Since vitamin B12 is water – soluble, anything the human body doesn’t use, it will get rid of.

Another major reason why B12 injections won’t work for weight loss is the fact that they are an inefficient source of vitamin B12. Since these supplements are fermented, by the time the human body finishes breaking down those multi-vitamins it takes, it will actually get a significantly smaller dosage of vitamin B12 than what’s stated on the label.

B12 Shots Side Effects

As long as B12 shots are administered properly, they are in general recognized as safe. Still, there are numerous side effects which patients might experience from these B12 injections.


The most common side effects involve nausea, mild diarrhea, upset stomach, headache, joint pain, a warm sensation and a feeling of pain at the site of the B12 injection, and a sense (or a feeling) that your entire body is swollen. If any of these B12 shots side effects become troublesome or severe, you need to let your doctor know immediately. There are also some serious and less common B12 injection side effects that need to be mentioned as well.

Possible cardiovascular effects include: a rapid heartbeat, chest pain, heart palpitations, difficulty breathing, and a feeling or sensation of tightness in the chest.

Musculoskeletal side effects imply: muscle pain, muscle weakness, leg pain, muscle cramps, and a swelling of the extremities (arms, hands, lower legs, ankles or feet).

Furthermore, vitamin B12 shots might cause these neurological side effects: numbness, a sense of confusion, a tingling sensation, dizziness, and a feeling of extreme fatigue or tiredness. You may also notice the following dermatological side effects with B12 injections: hives, itching, a red skin color on your face or anywhere on your body, and skin rash. Finally, some metabolic side effects can also occur including these: frequent urination, a sensation of extreme thirst, and rapid weight loss. Anyone receiving B12 shots needs to be aware of some serious side effects and dangerous drug interactions that may occur because this will make taking B12 shots that much safer.

B12 Shots Benefits

There are also many benefits when taking vitamin B12 injections such as the oral supplement’s immediate availability to the human body. According to the NIH (National Institutes of Health), injections or shots which go directly in the blood stream by-pass body’s absorption barriers, and can help those with malabsorption issues such as people who have undergone some intestinal surgeries or have intestinal disorders.

Moreover, B12 injections might help someone with megaloblastic and pernicious anemia which is, according to Mayo Clinic and NIH, a lifelong condition which occurs in 1-2% of older adults. This condition is treated with some high doses of B12 injections. Also, UMMC (the University of Maryland Medical Center) claims fatigue caused by a deficiency of the vitamin B12 is often alleviated with vitamin B12 shots that boosts energy.
