B12 Injection

---

Methylcobalamin the most bio-available form of Vitamin B12, i.e. it is the most readily absorbed.  Further to this research has shown that it remains in the body for a  longer period of time and at higher levels than cyanocobalamin, which  means that your body is supplied with vitamin B12 for longer if you use  methylcobalamin than if you use cyanocobalamin.   Methylcobalamin  is used primarily in your liver, brain and nervous system, in fact  methylcobalamin is the specific form of B12 needed for nervous system  health.  Because of methylcobalamin's importance in nervous  system health, it is also an important nutrient for vision. Research has  shown that methylcobalamin significantly improves visual accommodation,  while cyanocobalamin appears to be ineffective. Visual accommodation is  the ability to quickly shift your focus from something nearby to  something further away - this is often impaired by activities such as  staring at a computer screen for long periods of time.   The most  well studied use of methylcobalamin has to do with sleep - although the  exact mechanism of action is not yet clear, it is possible that  methylcobalamin is needed for the synthesis of melatonin. Research  indicates that methylcobalamin can modulate melatonin secretion, enhance  light-sensitivity, and normalise circadian rhythm (your body's 24-hour  clock). Because of this, individuals supplementing this form of B12  often report improved quality of sleep, often will require slightly less  sleep, and will not uncommonly report that they feel a bit more  refreshed when waking in the morning
