Vitamin B12 is an essential vitamin that is crucial to many components of our health. It is involved in helping form our DNA and red blood cells. It is also key for things like our overall brain and heart health. B12 is essential for energy production, which is why many people take it in supplements to help with fatigue and overall energy levels. In natural forms, B12 is found in most animal products and is sometimes used to fortify foods to add extra vitamin content. When it comes to weight loss and belly fat, B12, particularly B12 shots or injections, have gained popularity in recent years for their purported impacts on metabolism and fat loss. It’s important to keep in mind that there is no “magic pill” when it comes to weight loss and belly fat in general, and that research on humans and B12 for fat loss is still relatively limited. However, there is some promising evidence that B12 helps the body metabolize fat, and research has found that a B12 deficiency could actually be linked to excess weight and obesity. One large study found that those with higher blood levels of B12 had an overall lower risk of obesity. Furthermore, since B12 can help improve your energy levels, you may have more energy to conduct the exercise, therefore burning more calories and helping lose excess weight, including in the belly area.
