The primary function of B12 vitamins is to assist other chemicals in the body with the production of red blood cells. Red blood cells carry oxygen throughout your system, so a lower number of these cells mean that your organs are receiving less oxygen – and you may feel run down, irritable, and lightheaded.

B-12 shots work differently than oral supplements because they bypass the stomach and are absorbed directly into the bloodstream. This brings B-12 into action faster and more effectively for increased energy and vitality!
