I'm so sorry to learn about your daughter's health deteriorating so far before the true problem was discovered. Thankfully, she is slowly recovering with proper treatment! My youngest daughter and I just finished watching the video. It was also of particular interest to us because her doctor diagnosed her with low B12 several months ago and prescribed 5000mcg/daily -- FAR more than is in a typical multivitamin! (According to webmed, the typical general supplemental dose of vitamin B12 is 1-25 mcg per day).
