I have a somewhat mixed review - here are the facts and you can decide for yourself if it's worth it or not. Keep in mind that this is a private business and if you decide to do it, be prepared to pay a lot. First visit is about $350 with every subsequent at $250. Usually you will meet with a nutritionist which is another $90 and the vitamins will run you around $200.
I had a few visits with Dr Pelletier over the course of about a year. My symptoms weren't clear and PCP couldn't give a go...
