They gave me "special formulas" for mood which had neurotransmitter precursors, so yes amino acids, also fatty acids, vitamins. They said i had "pyroluria" so gave me B6 and zinc. You're right when you say it's too good to be true. After 4 months i was no better and they told me to do yoga and counselling, which i knew was heading down bullshit alley. It was nothing short of a joke. The cherry on the cake is that they say they have mercury and candida tests, but never carried any out on me.
