Yes. It has to do with absorbtion. Many of us lack the ability to absorb the B12 present within food. Therefore, swallowing pills will not cause it to enter the blood stream.
I’ve tried the sublingual tablets and letting it disolve under the tongue. I don’t get the same results.
I began my B12 overseas and have been able to acquire what I need there. I inject myself. It really isn’t hard to do.
I’ve never tried the shots. I hate shots . . . had to have shots after getting bitten by a stray dog when I was six, in the stomach, arm and butt.
So I take the sublingual and can usually tell a difference in 72 or so hours taking 2-3 twice a day.
How often do you do the shots?
Do you inject with the insulin needles?
