How does Vyvanse work in the body?
Vyvanse is a prodrug that, once ingested, is metabolized in the gastrointestinal tract and blood into dextroamphetamine.

These neurotransmitters are believed to play a key role in attention, impulse control, and executive function, helping to manage ADHD symptoms [2].
