Signs and symptoms: Many common symptoms can be caused by vitamin B12 deficiency, including weakness, tiredness, lightheadedness, heart palpitations, shortness of breath, pallor (pale skin), diarrhea, decreased appetite, nerve problems like numbness or tingling, visual changes and psycho-emotional problems like depression, memory loss or behavioral changes
For these patients, oral B12 supplementation (1,000-2,000 mcg daily sublingual methylcobalamin) provides comparable B12 repletion without injection
this prevents metabolic bottlenecks that might occur if one B vitamin is lacking
NICE and British National Formulary (BNF) guidance recommend 1 mg hydroxocobalamin on alternate days until no further improvement in symptoms is observed
Do not take iron supplements with coffee, tea, bran, or milk
