You could consider Vitamin B12 the “Superman” (or woman!) of vitamins. This water-soluble vitamin is vital for many important bodily functions, including the formation of red blood cells, DNA synthesis, and nerve regeneration. For this reason, it’s been used to help enhance athletic performance, fight fatigue, and provide additional energy to get through hectic schedules.
This vitamin exists in several forms, and because it contains a bit of a mineral called cobalt, the compounds within vitamin B12 are often referred to as cobalamins. All of the B vitamins play an important role in your body’s metabolism and health, but vitamin B12 plays a particularly prominent part.
The B vitamins, and particularly vitamin B12, play a vital role in how your body produces what it needs for energy. If you’re deficient in vitamin B12, an injection will definitely give your energy level a boost. In fact, one of the first signs of vitamin B12 deficiency is fatigue.
