Can not tell any difference when using this. Nothing at all. I have ridges on my thumbnail and when I take B-12 my nail will start to smooth out and the ridges get smaller - not with this B-12. They got larger and started to get some on my other thumbnail. No energy, no nothing, could not tell I was even taking this.
