The vitamin is delivered straight into your muscle, allowing it to be absorbed directly into your bloodstream
Providing an energy boost
So yeah, talk to your doctor first
If your deficiency is linked to a chronic condition that affects absorption, you may need injections long-term
This is one of the earliest signs that the injection is helping your body produce more red blood cells and improving oxygen transport
Common indications include: Pernicious anaemia an autoimmune condition where the stomach cannot produce intrinsic factor, a protein necessary for B12 absorption [8] [9] Malabsorption disorders including Crohn's disease, coeliac disease, or following gastric surgery Strict vegan or vegetarian diets with confirmed deficiency though high-dose oral B12 may be sufficient if no malabsorption exists Certain medications such as metformin or proton pump inhibitors that may interfere with B12 absorption [9] [10] Neurological symptoms including peripheral neuropathy, memory problems, or balance difficulties related to deficiency Diagnosis should be confirmed through blood tests measuring serum B12 levels, full blood count, folate, and often anti-intrinsic factor antibodies
