Injectable Vitamin B12 helps to revitalize the body, refresh the mind, and renew overall energy. B12 plays a key role in the normal functioning of the nervous system, the brain, and in the formation of the building blocks of every cell in the body. Many people have difficulty adequately absorbing vitamin B12 despite consuming foods rich in Vitamin B12 such as, fish, poultry, eggs, milk, and other dairy products. Getting Vitamin B12 injections bypasses the GI tract allowing up to 100% absorption into the body and straight into your cells. Vitamin B12 is a vital nutrient our body uses to keep our red blood cells healthy. Healthy red blood cells transport oxygen to our organs. This supplement intake will boost the production of these cells, which in turn, increase your energy levels, helping those with chronic fatigue or anemia. Maintaining sufficient Vitamin B12 levels also supports bone health, and can even improve mood and depression in those with a deficiency.
