N-Acetyl L-Tyrosine Supplement - for Brain Nutrition
N-acetyl l-tyrosine is the fastest-absorbed and most bioavailable form of the amino acid l-tyrosine, converted into two essential neuro-mediators:
Dopamine, which helps create a sense of well-being;
Noradrenalin (or norepinephrine), the natural brain stimulant.

Je le réécris : excellent pour contrer certaines déprimes, voire dépressions.

Je tenais à laisser un message positif pour ce produit. Je confirme, avec d'autres témoignages sur le Net, qu'il est d'une aide certaine dans certains cas de déprime, voire de dépression. Sans effet secondaire, même à long terme, il mériterait d'être plus connu.
