Question:
What affect, if any does B-12 injections have on our metabolism?

Do B-12 injections have any affect on our metabolism? I know it has something to do with being a help for those who may be deficient and fatigued, but I was wondering if it was true that it "speeds up" the metabolism. Thanks in advance for your reply.    — yourdivaness (posted on April 14, 2003)

Hi, I don't really know if it helps our metabolism or not but I know I couldn't make it without mine. My bloodwork is great but if I don't get one every couple of months, my energy just totally goes away. I could sleep all the time. Its amzing to me that a simple shot could make that big of a difference..

Vitamin B12, or Cobalamin is involved in the metabolism of folate (folic acid), maintaining the myelin sheath on nerve cells, and forming healthy red blood cells. (This came straight from my RN nutrition book). As for speeding up metabolism in the sense you are speaking of, I would say that it does not have a DIRECT effect. You do have to consider this though...without all of the above functions of B12, you would have no energy at all to exercise. Exercise itself increases metabolism. I will tell you this, a B12 shot makes you feel GOOD! I hope this helps.
