I like to think of Cysteine as a turnstile for neurotransmitters that prevent huge swings in them.
đ§ âď¸ NAC supports balanced brain chemistry by modulating glutamate and dopamine pathways.
Through the cystine-glutamate antiporter, it helps regulate extracellular glutamate levels, preventing excessive excitatory signaling while promoting stable dopamine function and transporter activity. This contributes to improved mood regularity and reduced impulsivityâkey benefits observed in contexts such as ADHD and mood dysregulation. A valuable adjunct for neurotransmitter homeostasis. đż
