It is possible that it will be several weeks before both your levels of vitamin B12 and your symptoms (which may include excessive weariness or a lack of energy) begin to improve
For example, if you have a deficiency and need regular B12 injections, hydroxocobalamin can be given once every 3 months, whereas cyanocobalamin would need to be given every month
Vitamin B12 is very safe, however if you do have an excessive amount it can lead to side effects Here at The Nurse Clinic we administer B12 Injections for Dietary or Wellbeing purposes unless you have evidence from your GP showing diagnosis of a medical condition which can lead to B12 deficiency The recommended guidelines for the administration of vitamin B12 injections can be found below however generally it is suggested that the following is advised: For Dietary or Wellness Every 6 months For B12 Deficiency Every 2-3 months INTRAMUSCULAR (IM) will be released into the systemic circulation reasonably quickly, bypassing the gastric system therefore you will absorb much more
Some people may have mild symptoms at first, while others may notice more significant changes over time
