For pernicious anaemia or malabsorption disorders , the standard treatment in the UK involves intramuscular (IM) injections of hydroxocobalamin, the preferred form of B12
NICE notes that pernicious anaemia is the most common cause of Vitamin B12 deficiency in those aged 40-70, with an average onset age of 60 in white people and 50 in black people, although it can affect black women at a younger age
Recommended Use: Vitamin B12 is recommended for those with fatigue, poor concentration, or low red blood cell levels
B12 injections effectively treat deficiency symptoms including chronic fatigue, mental fog, memory problems, numbness or tingling in extremities, pale skin, general weakness, and irritability in affected patients.
