The human body cannot produce this amino acid on its own, so it is completely dependent on its intake through diet and supplements. 


In the body, phenylethylamine is formed from it, which has the function of a neurotransmitter and is associated mainly with feelings of happiness and satisfaction. The amino acid tyrosine is also formed from phenylalanine and further participates in the synthesis of hormones. These include the hormones adrenaline and dopamine, which also act as neurotransmitters. They are key to brain functions such as memory or concentration but they are also involved in coping with stressful situations.
