It is also a very common vitamin used to help the body use fat and carbohydrates. This is why many weight loss clinics will offer B12 injections. I’ve personally tried the B12 injections out of curiosity. I didn’t feel any sort of adverse effects, and I did notice a slight increase in metabolism. I have not compared the injections to oral consumption to compare effectiveness.
Common sources of Vitamin B12 are multivitamin supplements, chewables, and food. Food sources include eggs, fish, meat, etc.
One thing I have learned though is that there are different compounds of Vitamin B12 which have different absorption rates. Cyanocobalamin is not absorbed as effectively in the body as methylcobalamin. When you look for vitamins next time, check the label for which one you are taking.
