If your body lacks sufficient B12 due to dietary reasons (e.g., youre vegan and not supplementing) or, more commonly, due to an inability to absorb B12 from your gut (e.g., pernicious anaemia, certain stomach conditions, or medications), then replenishing those levels with an injection will directly address the cause of your fatigue
