Vitamin B12 (Cyanocobalamin) Is A Water-Soluble Vitamin Necessary For Energy Production; For Nervous System Function As It Is Needed To Produce Myelin, The Fatty Substance That Forms A Protective Sheath Around Nerves; For The Production Of Acetylcholine, A Neurotransmitter That Helps With Memory And Learning; For The Synthesis Of Red Blood Cells; For Producing The Genetic Materials, Dna And Rna. Vitamin B12 Works With Folic Acid To Control Homocysteine Levels. Research Shows That High Levels Of Homocysteine May Dramatically Increase The Risk Of Heart Disease And Osteoporosis. Vitamin B12 Is The Most Complex Of The Vitamins And Is The Only Naturally Occurring Organic Compound That Contains Cobalt. Vitamin B12 Deficiency Is More Often Caused By Improper Absorption (Often Because Of A Lack Of 'Intrinsic Factor,' An Enzyme Required For Vitamin B12 Absorption) Than By Inadequate Intake. However, It Is Easily Depleted In Those Individuals On A Vegetarian Diet, Making Supplementation Essential. B12 Has Provided Relief In Fatigue, Increased Nervous Irritability, Mild Impairment In Memory, Inability To Concentrate, Mental Depression, Insomnia And Lack Of Balance.

Vitamin B12 Dei¬ciency Can Occur Over Time In Strict Vegetarians. Under The Right Circumstances, Supplementing Folic Acid Can Mask Vitamin B12 Depletion. Normally Folic Acid Is Recycled As A Methyl Donor By Being Reactivated By Vitamin B12, Acting Itself As A Methyl Donor To Folic Acid. When Tissue Folic Acid Levels Are Low, A Co-Existing Vitamin B12 Dei¬ciency Will Be Manifested Through Even Greater Failure Of Folic Acid Metabolism, Ultimately Leading To Pernicious Anemia. However, Persistent Vitamin B12 Depletion Also Leads To Neurological Damage. The Concern Is That New Daily Supplemented Folic Acid Can Overcome The Metabolic Problems That Lead To Pernicious Anemia Without Averting Neurological Damage. Because The Neurological Damage Evolves Slowly, Supplementing Folic Acid Without Also Supplementing B12 Can Mask A True B12 Depletion Allowing Neurological Damage To Proceed Unsuspected. It Is Always Recommended That Folic Acid And Vitamin B12 Be Supplemented Together. Impaired Neurological Function In The Elder Population Due To Vitamin B12 Depletion Can Be An Important But Unsuspected Factor When There Is Not Also Evidence Of Anemia. Many Physicians Fail To Investigate Vitamin B12 Depletion If There Is Not Also Evidence Of Anemia, Yet Two Of The Most Depleted Nutrients In The Elder Population Are Vitamin B12 And Folic Acid. In All Cases Of Impaired Mental Function Or Depression Vitamin B12 Status Should Be Determined And Treated Accordingly
