I'm 60 yrs young and after my Mom was diagnosed with Dementia I began in earnest researching alternative treatments rather than the traditional treatments. I ran across Vitamin B12 and was astounded. Against my Mom's Dr. BUT with my Mom in agreement I took her for some B12 injections- the diff was nite and day albeit only a temporary solution.
After further research I discovered many facts:
here in N. America the standard ppo (acceptable level of B12) for B12 in the body is 220. In Asia the standard is 550 ppo- The minute anyone in Asia falls below 550 they are immediately given B12- either injection or sublingual. I found it astonishing that Asia has the lowest rate of Dementia associated disease in the industrialized world....coincidence?
As we age many of us, but not all, suffer a degradation of an enzyme in the digestive tract that breaks down B12 from foods we eat thus leading to B12 deficiency.
B12 is very important in the production of red blood cells- red cells contain coagulants- notice many of the elderly have bruises and bleed very easily.
B12 is also important in the manufacture of the sheathing that covers and insulates the nerves in the brain- Drs believe this degradation of the sheathing leads to further issues in regards to dementia .
As far as anemia before I began taking B12 I had itchy sores on my legs and bled very easily. I later found out anemia runs in my family. Since taking the B12 no mores sores and I don't bleed easily.
2 yrs ago I went to the hospital for a sinus op. Operated on Fri noon and by Sat nite no more bleeding- When I went for the followup the Surgeon was surprised at the rate of healing. I mentioned that my wife and I were taking sublingual B12. He told me the medical circle are now looking at B12 as the "miracle vitamin". I now have more energy and feel great. As always consult your Dr. All I can say is I researched B12 for months because of the circumstances.
