Advice & Tips: Early on in my PD this supplement was more effective. However no one currently formulates this compound so you have to buy the bulk compound and fill capsules which can be a problem if you have coordination difficulties.

Advice & Tips: I switched from taking L-Tyrosine to taking Acetyl L-Tyrosine because of better absorption and delivery of the Tyrosine across the blood brain barrier. Also it is less affected by the ingestion of other amino acids (proteins).
