Vitamin B12 boosts energy levels and/or stamina and can even help to speed up metabolism. This can actually affect an individual's weight and has been used along with other therapies in weight loss programs. Having improved energy benefits mood, helps the body overcome chronic fatigue, and can also improve an individual's level of physical activity. Many benefits reported by persons who routinely receive Vitamin B12 injections include: improved sleep, reduced allergies, reduced stress and depression, improved mood, and less frequent and/or severe headaches. A Vitamin B12 injection contributes to a healthier immune system, and is essential for proper cellular function, including the making of DNA during cell division and the proper formation of RBC's (Red Blood Cells).
Vitamin B12 is the only vitamin not readily absorbed by the stomach or intestinal tract, so an injectable form is extremely beneficial. People with anemia or other health concerns related to low energy or fatigue, may require weekly injections (for several weeks) of Vitamin B12, this is mainly because the oral form is less dependable. Vitamin B12 injections are most effective when taken at regular intervals, usually weekly for 4 weeks, then monthly thereafter. The great news is, the benefits are typically experienced within 4-6 days of receiving a B12 injection. Most people experience an increase in their energy level or stamina, and in general feel better!
