Why does vitamin b12 give you energy?

    B12 deficiency can cause anemia, which then will cause a feeling of weakness, tiredness and possibly depression.  Thus, taking a B12 supplement could help boost your energy.

    Fuels for our body include carbohydrates (obviously) but also fats and proteins. Vitamin B12 is important for metabolism in every cell of the body. A good analogy in my opinion is one from a website the link to which I attached. Quote directly from their article:

    “If carbohydrates, fats, and other nutrients are fuels and your body is the machine, vitamin B12 serves as the spark plug that ignites the engine to run.”

    This is not exactly how it works. Vitamin B12 is just part of a complex process and in fact, often regenerates folate in the body, which means that appropriate amount of B9 (folic acid) can mimic the effects of B12 (not all, but many).

    To answer your question, B12 does NOT GIVE you energy. It is more like an assistant to metabolism of energy sources.
