I purposely waited months to write this review. This time last year I had been suffering from crippling headaches in conjunction w/ nausea and vomiting that never really seemed to go away and chronic fatigue. I had no idea how I was going to continue to keep my job and my quality of life was terrible. I spent thousands on specialist and even had a minor surgery, only be told there was no definitive answer to it was best to take my gallbladder out. I was sick, depressed and running out of options. After researching online, I found Doctors Nutrition. This may sound dramatic, but they have changed my life. I did blood work, they sat w/ me (for an hour) and explained the findings. I had thyroid, hormone imbalances and some vitamin deficiencies. Got my supplements, gave it a little time and I am a new women! This is not guesswork. The follow up blood work and they way you feel is proof that it's working. The blood work and supplements cost money, but considering that I was looking at paying for another surgery and missing weeks of work if I had listened to the specialist, I think I came out on the winning end. THANKS DOCTOR'S NUTRITION! They are kind, caring professionals & I would recommend to everyone.
