Vitamin B12, also known as cobalamin, is a water soluble vitamin vital to the human body for its role in functioning of the brain and nervous system, and formation of blood. It also plays a valuable role in fatty acid synthesis and producing energy as a result of improved oxygen absorption.
Vitamin B12 is often used to treat chronic fatigue syndrome and anaemia, both conditions that are the most dangerous of all B12 deficiency symptoms because fatigue and low energy result in lack of proper exercise and activity. Some who have taken vitamin b12 shots to treat these disorders have noticed weight loss which has been attributed to the vitamin. Along with the increased metabolism activity when taking vitamin B12, the weight loss may also be a result of increased energy associated with feeling better.
Vitamin B12 deficiency is rare as it is stored in the body for long periods of time. Where possible it should be obtained from proper diet and food consumption. But B12 injections are much quicker acting and more of the vitamin is absorbed and retained by the body as it is injected directly into the muscle. This is why injections give a much quicker energy boost if that is what you require. However if you are not B12 deficient, this could ultimately be causing more harm than good. Vitamin B12 injection energy boosts are short lived and to maintain the effects, you must continue to receive the injections. And any weight you lose will be gained back when you stop taking the injections. When considering B12 shots for weight loss as your sole goal in taking these b12 shots you should definitely refrain because while vitamin B12 weight loss does exist, it is definitely NOT a very long term plan, especially if taken in the form of shots/injections. However, if you feel your diet is low in vitamin B12 ( especially if you are vegetarian) and you also want to take care of the many vitamin B12 benefits than feel free to try out some supplements which have much lower risks for your health than taking B12 injections for weight loss.
Vitamin B12 should be consumed in a healthy diet plan which includes a nutritional balance from all the food groups. Vitamin B12 is obtained from meat, milk, eggs, fish and shellfish and so, often, strict vegetarians are probably lacking in daily requirements and should take B12 supplements to meet their daily needs.
There is no clinical evidence or proof that Vitamin B12 injections for weight loss or excessive amounts of Vitamin B12 supplements will work by themselves, but making sure you meet daily requirements on this vitamin and all nutrients will make you feel better in the long run and ultimately improve your energy level which will facilitate adding one of the many diets for quick weight loss in your lifestyle and sticking to it. If you want an alternative solution to B12 shots for weight loss as “low effort” diet ( and of course low rewards in weight loss) you might want to instead try a green tea for weight loss diet which is simply adding a few cups of green tea in your daily drinks in order to help your body burn more fat. The main subject of this website is finding the best vitamins and their are of course some other vitamins for weight loss that can assist you! As a final reminder, B12 shots for weight loss do somewhat work but vitamin B12 shots are mainly reserved for those who have trouble absorbing vitamin B12 and these same people are usually suffering from symptoms of vitamin B12 deficiency which usually entails low energy and when their deficiency is solved they are naturally prone to be more active which often means weight loss. If you are not suffering from deficiency symptoms, B12 injections for weight loss only is probably a waste of your time and might be harmful to you.
