Anyone who is age 40 and up needs to have their vitamin B12 tested. Just do it. If you have any numbness, tingling, etc. of the peripheral nerves (feet, face, hands), be tested right away.

I had a severe B12 deficiency in 1997-99. I had to ask my doctor 2 times to have the test (2nd time in writing). My homocysteine level was also elevated.

Vitamin B12 is necessary for every cell in your body. Without B12, a person dies. Just ask Thomas Addison (he's dead, but read his writings). B12 also helps to heal peripheral nerves; after surgery, for Bell's Palsy and Shingles, and other nerve damage.

B12 was also shown by the Mayo Clinic to go to cancer in an attempt to heal that.

People who have had the bioweapon posing as a vaccine have had peripheral nerve damage. They may want to take high doses of METHYLcobalamin (works right away in the body) instead of cyanocobalamin (needs to be converted by the liver first).

Always check with your doctor first. Then do what you want.
