B12 injections, also known as cyanocobalamin, or hydroxocobalamin, tend to be a more reliable delivery vehicle for those who require a precise dose or just want to be certain that their supplementation efforts are working
It is a component of hemoglobin and myoglobin, proteins in the red blood cells and muscles that store oxygen and deliver it to your brain, other organs, and working muscles, which helps you feel physically and mentally energized
For individuals requiring supplementation due to confirmed deficiency or malabsorption, therapeutic doses vary considerably depending on the underlying cause: Dietary deficiency : 50150 micrograms daily orally, or cyanocobalamin tablets as prescribed Pernicious anaemia : Initially hydroxocobalamin 1 mg intramuscularly three times weekly for two weeks, then maintenance injections every two to three months [3] Neurological involvement : More intensive regimens may be required, with hydroxocobalamin injections on alternate days until symptom improvement [3] NICE guidance emphasises that supplementation should be evidence-based rather than speculative

The lack of B12 affects the production of red blood cells, leading to reduced oxygen transport and poor muscle function
