Vitamin B12? Are you taking the best form?'
The best form of Vitamin
B12 has two active co-enzyme forms: methylcobalamin – Used in
folate metabolism and brain development, and adenosylcobalamin – Plays a role in energy metabolism and the formation of myelin
around nerve cells.
According to this review suggests vitamin B12 deficiency should
be treated with a combination of these two forms to achieve the best
clinical results, stating also that oral versus intramuscular routes can
be equally effective.
Regarding the route, it has been proved that the oral route is comparable to the intramuscular route for rectifying vitamin B12 deficiency.

Deficiency Symptoms:
Vitamin B12 deficiency symptoms are both Hematological (pernicious anemia and neurological. Megaloblastic anemia may result because of the effects of the B12.
Clinical signs of folate metabolism deficiency: shortness of breath, fatique, weakness, irritability, ore tongu, decrease in blood cell counts (red, white and platelets).
Neurological symptoms are seen as a progressive neuropathy with loss of position sense and ataxia. If repletion of B12 is not performed then permanent neurological damage, including degeneration of nerves and spinal cord can result.
Recent evidence suggests that mental symtoms of depression and fatique are detectable before anemia develops.
B12 is vital to prevent of homocystine accumulation (toxic metabolic byprodduct linked to cardiovascular disease connective tissue abnormailities.
Dietary Sources:
Cobalamins are strictly from animal food, not in plant food.
RDA:for B12 as of 1989 is 2.0 μg daily (micron, or microgram 1x10−6 )
No toxic effects of oral Vit 12 have been shown, even in doses over 1000 μg a day
