I have no research to back this up, but after keeping track of how I feel after I consume phenylalanine for the past two months, I am almost certain I’m allergic in some way. Within twenty minutes of ingesting it I feel dizzy and my head starts to buzz (for lack of a better description) and itch in the scalp area.

I anyone has had previous experience with Aspertane or Phenylalanine, I would really love to know. The research online is far too contradictory for me to get anywhere with.
