2. It maintains the structure around the myelin sheath, which is the covering around nerve cells
3. It is needed for making use of protein
4. Together with Folic Acid, Vitamin B12 aids in regulating the formation of red blood cells, helps in utilizing iron and preventing anemia
5. It aids in cell formation
6. It assists in the synthesis of proteins needed for cardiovascular function
7. It helps convert Homocysteine, a toxic substance in the body, into methionine which is required to build protein

9. Studies have looked at how Vitamin B12 can potentially be used by people with HIV/aids, asthma, shingles, Parkinson’s Disease, Bell’s Palsy, Multiple Sclerosis, Alzheimer’s, depression, Diabetic neuropathy and other neurological disorders since B12 helps to protect against neurological deterioration.

Notes and/or Cautions:
Because most food sources of B12 come from animal products, strict vegetarians and vegans definitely require supplementation. It may take up to 5 years before signs of deficiency show up.

Certain pharmaceuticals may block the absorption of B12 such as anticoagulants, antigout medications and potassium supplements. B12 may be depleted by alcohol, smoking and lack of stomach acid

Methylcobalamin is a superior choice. Unfortunately, most supplements contain the form cyanocobalamin because it is cheaper to manufacture, but which is harder for the body to absorb.
Vitamin B12, in the methylcobalamin form is best taken sublingually, in other words, under the tongue. It also works best if taken with folic acid and the other B Complex vitamins

Recommended Dosages for Maintaining Good Health (for Adults): 200-400 mcg
