Vitamin B12 plays an essential role in your body

Vitamin B12 is a water-soluble vitamin that is part of the B vitamin family. It is also known as cobalamin. It is found naturally in animal products, such as meat, fish, eggs, and dairy products. It is also available in supplement form.

Vitamin B12  plays an essential role in your body and optimal health, including the creation of red blood cells, DNA synthesis, and nervous system function. Vitamin B12 is also involved in the metabolism of fat and protein. It also helps the body convert food into energy.

Key Benefits of Vitamin B12 for Weight Loss

Vitamin B12 has been linked to being obese and overweight

Low levels of vitamin B 12 have been linked to obesity and weight gain. Although B12 vitamin  deficiency is considered to be rare, one study found that people who had low levels of vitamin B12 were more likely to be obese or overweight. Furthermore, children with a high body mass index (BMI) were also found to have low levels of B12,

Conversely, adequate levels of vitamin B12 are linked with lower levels of weight gain or obesity. Research has also shown that vitamin B12 can boost metabolism and promote the burning of fat cells. 

Likely because if these studies, some weight loss clinics offer vitamin B-12 injections to support their weight-loss programs. Those who advocate for vitamin B12 injections say the shots increase metabolism and energy levels, both of which can aid in shedding excess weight and body fat. Let’s take a closer look.

Metabolism

Vitamin B12 is essential for metabolism. It helps the body convert food into energy, and it also helps the body use fatty acids for energy. Without enough vitamin B12, you cannot properly metabolize food, and this can lead to weight gain. A slow metabolism will also make it difficult to lose weight.

Provides Energy

In addition to increasing your metabolism, low levels of vitamin B12 can cause fatigue. Unfortunately, many of us consume extra calories in order to get the fuel and energy we need for everyday activities. Fatigue also causes a lot of us to be more sedentary. Both of which are not conducive to weight management. 

However, proper levels of vitamin B12 can improve your energy levels and allows you to increase your physical activity and weight loss efforts.

You may benefit from vitamin B12 supplements

If you are deficient or have low levels, you can also take a B12 supplement. The recommended daily allowance of vitamin B12 is 2.4 micrograms (mcg) for adults over the age of 18. However, for people who are trying to lose weight, the recommended dose of vitamin B12 is 500-1000 mcg per day. 

Vitamin B12 supplements are available in many forms, including tablets, capsules, liquids, and injections. The most common and effective form is cyanocobalamin, a manufactured version of vitamin B12, which is readily absorbed by the body.

Injections are the most easily absorbable form of vitamin B12, as they bypass the need for absorption by the gut. However, they are not necessary for most people and usually must be administered by a health care professional. Supplements and fortified foods are sufficient for most people trying to lose weight.

The good news is that you don’t have to worry have taking too much vitamin B12. The side effects from taking too much vitamin B12 are rare but can include diarrhea, headaches, and dizziness. However, since vitamin B12 is a water-soluble vitamin, it is excreted in the urine and does not build up in the body. This means that it is very difficult to take too much of this nutrient.

If you’re interested in taking vitamin B12 for weight loss, speak with your doctor first. They can help you determine if supplementation is right for you and recommend a dosage based on your individual needs. 

Pregnant women and breastfeeding mothers should also consult a healthcare provider before taking any supplements. The same goes for people with medical conditions or taking medications that could interact with vitamin B12.
