Yo DR L.A.L.. I also thought this would be a nice option instead of shots ( I have some strange pains with the shots some times )..but I won't recommend it.. I found a users reply for you on a health forum..and no effectiveness study of this yet.
"" Hello there!
Please DO NOT buy b12 patch from b12patch.com. It is useless!! I have been b12 deficient for 4 years now, and have been getting shots, and felt much better. However, when I discovered that there is more “convenient” way of getting b12 through the patch, I decided to give it a try. I bought couple of boxes back in December 2006 and told my doctor that I will try them. She agreed. However, she said I must be back in a month and she will check my b12 level. I waited two months, probably having a “placebo” effect from the patch. I started feeling really sluggish and numb, and went to take a blood test. My b12 plunged to really low levels, showing that there is no effect from the patch. I just want everybody to know that it does not work and prevent other people from spending money on it. Please DO NOT BUY IT!! There were no comprehensive studies done to prove the effectiveness of the patch.""
I think until there is a study done on this.. we should leave it where it is
