I had started using Multigenics from Metagenics quite a few years ago- around six or seven- which was around the time when my daughter had been working for a Gastric Bypass doctor. Therefore, it was easy to get the vitamins there. That being said, when she left, we had no place of getting them. I started to feel much worse, including my nails. I found them online, thankfully, so I'm all set now. I've also, however, started using Cal Apatite Forte as well.
