Function #1: L-Cystine helps downregulate excitatory neurotransmitters.
L-Cystine is a key ingredient to an enzyme known as PNMT (phenylethanolamine-N-methyltransferase). This enzyme system takes the long lasting stress neurotransmitter norepinephrine and converts it to the short lasting stress neurotransmitter epinephrine. This supports your nervous system in ‘coming down’ from an exciting event and then switching to a relaxed state gently and naturally.
